An active matrix liquid crystal display device has a plurality of unit pixels being arranged in a matrix configuration, each unit pixel being divided into a plurality of subpixels. Each of the subpixels has a subpixel electrode, a pixel transistor connected to the subpixel electrode, and a voltage controlling capacitor connected to the subpixel electrode. A voltage controlling capacitor line for supplying a compensation voltage signal is connected to the voltage controlling capacitor so that after the writing to the subpixel has been completed, the potential of the compensation voltage signal is varied to modulate the potential of the subpixel electrode to be a predetermined voltage, using the voltage controlling capacitor. Such combining of spatial dithering attained by a pixel-dividing technique and a capacitively-coupled driving method eliminates the need for digital-to-analog converter circuits, attains gray scale display based on a digital image signal, and achieves a reduction in power consumption.

However, the above-mentioned second conventional example has the following problems. (1) In the second conventional example, both the scanning-side driving circuit and the signal-side driving circuit are formed of polycrystalline silicon. Therefore, as the number of pixels increases, the horizontal scanning time becomes shorter, and it is impossible to operate at the required speed, and it is driven as a signal side formed of polycrystalline silicon, which has worse characteristics than monocrystalline silicon. [2] In the second conventional example, when a unit pixel is divided and a plurality of sub-pixels are configured, the signal lines are individual wirings, and the scanning lines are common wirings to be used as the wiring structure of the signal lines and scanning lines. In the above structure, in particular, when the unit pixel is divided into R (red), G (green), and B (blue) for color display, the number of connection pins on the driving circuit increases dramatically. As a result, the incidence of poor connection will increase, and the image quality such as display defects will decrease. (3) In the second conventional example, gray-scale display is performed by digital signals to prevent an increase in power consumption. However, when the second conventional example is applied to a display unit of a message terminal or a mobile phone, reduction of power consumption is even more required. (4) In the second conventional example, the pixel electrodes Tr1, Tr2, Tr3, and Tr4 are used to drive the pixel electrodes 155a, 155b, 155c, and 155d for grayscale display, but the grayscale of a unit pixel The balance of the grayscale display of adjacent unit pixels is displayed, and the density on the display screen will be displayed in a band shape, and a fixed pattern (fixed image) will be visible and the level of the LCD panel will be reduced. The object of the present invention is to provide a liquid crystal display device and a driving method thereof, which solve the above-mentioned problems, and without the digital / analog conversion circuit, can perform grayscale display according to the digital scene image number, and can achieve the peripheral driving circuit.

Description of the invention (t8) 31 for display control. Also, the liquid crystal display device in the aspect 1 of the present embodiment adopts an area grayscale display method. Therefore, the unit pixel 15 is composed of a plurality of (four in the aspect 1) sub-pixels P1, P2, P3, and P4. The sub-pixel pi includes a sub-pixel electrode M1, a pixel transistor Tr1 composed of a thin film transistor (TFT: Thin Film Transistor), and a voltage-controlled capacitor section C1 for performing capacity-combined driving described later. The other sub-pixels p2 to P4 are the same as the sub-pixels pi, and are composed of the sub-pixel electrodes M2 to M4, the pixel transistors τΓ2 to Tr4, and the voltage control capacity sections C2 to C4. In aspect 1 of this embodiment, the electrode area ratio of the aforementioned sub-pixels M1 to M4 is formed in a size corresponding to the weighted portion of the digital image data. That is, the area of the sub-pixel electrode M1: the area of the sub-pixel electrode m2; the area of the sub-pixel electrode M3; the area of the sub-pixel electrode M4 = 1: 2: 4: 8. Then, the first bit data of the 4-bit 疋 image data corresponds to the sub-pixel P1, the second bit data corresponds to the sub-pixel P2, and the third bit data corresponds to the sub-pixel? The 3 corresponding '4th bit data corresponds to the sub-pixel p4. The size of the above-mentioned image electrode corresponds to the weighted part of the digital signal, so 16 gray levels can be displayed according to the digital image data. The electrode area of the image electrode is actually the area of the part that contributes to the light modulation. For example, when it is of the transmission type, it means the actual area except the area of the part covered by the electrode area with the light-shielding body. Each early pixel 15 has a wiring structure in which scanning lines GL are individually wired to each pixel, and signal lines SL are commonly wired to all sub-pixels. By the above-mentioned wiring structure used to form sub-pixels, it can solve the conventional example (the paper size of the paper is suitable for households (CNS) A4 specifications (2iQx297 public love) ------------- ---------- Install ...-.......... :: Order ......- Line · (Please read the back first (Notes for re-filling and writing this page) -21- 538398 A7 ____ _B7____ V. Description of the invention b) The problems of the Japanese Patent Publication No. 10-68931). In particular, since the signal-side driving circuit 12 in this embodiment 1 is formed of single-crystal silicon, it cannot be used to connect the signal line SL with a larger pitch. Therefore, without such restrictions, the number of scanning lines GL is large. Accessible. Accordingly, in the first aspect of the present embodiment, the scanning lines GL are individually formed, and the signal lines SL are collectively formed. In addition, the liquid crystal display device in the first aspect of the present embodiment uses the capacity-combined driving method (a certain relative electrode potential) disclosed in Japanese Laid-Open Patent Publications Nos. 2-157815 and 10-39277. When explaining the specific structure, the voltage control capacity wiring 32 is wired to each unit pixel 15 and one of the aforementioned voltage control capacity sections C1 to C4 is formed through a common connection line 33 with the voltage control capacity wiring 32, respectively. A structure connected to the voltage control capacity wiring 32. Therefore, it is possible to prevent a reduction in display level due to a penetration voltage (a decrease in voltage of a pixel electrode due to parasitic capacity). Furthermore, by using the above-mentioned independent voltage control capacity wiring 32, a scanning-side driving circuit can be formed compared to a structure in which a scanning signal and a compensation voltage are superposed on a scanning line (for example, Japanese Laid-Open Patent Publication No. 2-158815) ii low voltage. In addition, as described later, the driving circuit 31 for applying a compensation voltage is configured to change the compensation voltage signal after the writing of all the sub-pixels constituting the unit pixel is completed as shown in FIG. Electrode potential modulation. Therefore, for example, compared to a configuration in which the voltage control capacity wiring 32 is arranged at each pixel and the voltage control capacity wiring portions C1 to C4 are connected to the voltage control capacity wiring 32, respectively, the number of wirings of the voltage control capacity wiring 32 is smaller. This paper Standards are applicable to China National Standard (CNS) A4 specifications (210X297 mm) • 22-538398 A7 B7 V. Description of the invention (20) It can improve the aperture ratio and simplify the drive control. Also, one horizontal scanning frequency (here, the so-called "one horizontal scanning" means that in the capacity-combined driving method like the present invention, the compensation voltage is changed and the electrode potential of the sub-pixel is adjusted after the writing of the sub-pixel is completed) It becomes smaller and can reduce power consumption. Furthermore, in the driving method using the capacity-combining method like this embodiment, each time a pixel is driven in reverse (if a sub-pixel is regarded as a normal pixel, it is equivalent to… inverted driving), it is grayed out due to the combination of capacity. The first order characteristic (γ characteristic) will be non-linear and non-linear with unevenness. This will cause deterioration of the display level. Regarding this point, as in this embodiment, each unit pixel is used for reverse driving (if a sub-pixel is regarded as a normal pixel, it is equivalent to 4Η reverse driving), which can improve the linearity of the Y characteristic, and can Increase the display level. Moreover, instead of the driving circuit 31 for applying a compensation voltage, the scanning-side driving circuit Π has a function of applying a compensation voltage, and at the same time, a voltage control capacity wiring 32 can be connected to the scanning-side driving circuit 11, so that only the application of the compensation voltage can be reduced. The circuit area of the driving circuit 31 portion. Here, the area ratio of the sub-pixel electrode is set to 1: 2: 4: 8, so the voltage control capacity section is also configured to have a corresponding capacity value. That is, the value of the voltage control capacity section ci: the value of the voltage control capacity section C2: the value of the voltage control capacity section C3: the value of the voltage control capacity section c4 = ι: 2: 4: 8. Therefore, the variation of the pixel electrode potential can be reduced, and a good image quality can be obtained. Further, each of the pixel transistors Tr1 to Tr4 is set so that the power of the ON current corresponds to the magnitude of the weighted portion of the digital video signal. Specifically, the channel width of each of the pixel transistors Tr1 to Tr4 in this embodiment is the same as the paper size of the sub-pixel table. The Chinese national standard (q ^ S) Α4 specification (210X297) is available. (Please read the notes on the back first. (Fill in this page again) | •, Ding 丨 line-23- 538398 A7 _ B7 V. The size of the electrode corresponding to the description of the invention (21) is to form a channel width ratio of 1: 2: 4: 8. With the above structure, appropriate writing can be performed. Moreover, instead of making the channel widths of the pixel transistors Tr1 to Tr4 different, the channel length can also be set to a size corresponding to the weighted portion of the digital video signal. Also, the channel width and channel length can be made different, and the power of the ON current can be set to a size corresponding to the weighted portion of the digital video signal. In addition, in the first aspect of the present embodiment, the scanning-side driving circuit 11 is formed of polycrystalline silicon, and is a built-in driving circuit that is simultaneously built in the manufacturing process of the liquid crystal display section 10. On the other hand, the signal-side driving circuit 12 is formed of a monocrystalline stone, and the 1C chip of the monocrystalline silicon is mounted on a dynamic matrix substrate by a COG (CHIP ON GLASS) method. The mounting method of the 1C chip is not limited to COG, and a mounting method such as TAB can also be used. As described above, the signal-side driving circuit is formed by monocrystalline silicon, and the power consumption can be greatly reduced. The reason will be described below. In recent years, the demand for liquid crystal display panels having a narrow frame area, which reduces the area occupied by circuit driving panels of peripheral driving circuits, has increased. Therefore, it is proposed to form a peripheral driving circuit by using polycrystalline silicon and make a built-in driving circuit. However, when all driving circuits are formed of polycrystalline silicon, the moving speed of the transistors formed of polycrystalline silicon is extremely slower than that of the transistors formed of single crystal silicon. Therefore, the power consumption will increase when the driving circuits are formed of polycrystalline silicon. On the other hand, if all the driving circuits are formed of single crystal silicon, the requirement of narrowing the frame is violated. Here, the requirement of narrow frame is slightly violated, but in order to reduce power consumption, one of the scanning-side driving circuit and the signal-side driving circuit is formed of single crystal silicon. Here, the state of the signal-side driving circuit 12 is formed by silicon *, and the signal-side driving circuit 12 is the size of the paper-side driving circuit 12. Applicable to China National Standard (CNS) A4 (210X297 mm) -24- 538398 A7 B7 Description of the invention h In addition to a latching circuit and the like in addition to the shift register, and the circuit structure is more complicated than the scanning-side driving circuit 11, the power consumption is large. Therefore, the power consumption on the signal-side driving circuit 12 accounts for a considerable proportion of the power consumption in the entire liquid crystal display panel. From this, it can be seen from the viewpoint of effectively reducing power consumption that it is preferable to form the signal-side driving circuit 12 with monocrystalline silicon. In the first aspect of the present embodiment, the signal-side driving circuit is formed of monocrystalline silicon and the power consumption is reduced.

In Fig. 5, "(i, j)" shows the signal line SH of the i-th and the scan line GLj of the 』-'. In addition, a liquid crystal panel structure corresponding to a VGA (64 × 480 pixels) is taken as an example. Of course, the area of the sub-pixels is formed in a size corresponding to the weighted portion of the digital signal, and the sub-pixels are drawn with the same size. The arrangement state of FIG. 5 is different from the actual arrangement state. However, the explanation of the display operation is that the signal line SL and the scanning line GL can fully determine any one of all sub-pixels. Therefore, the pattern diagram of FIG. 5 is used. Fig. 6 (a) relates to the timing of the n-th pixel, and Fig. 6 (1)) relates to the timing of the n + 1th pixel. First, the image signal is borrowed from an external data conversion circuit (the paper size in the picture does not apply to the Chinese National Standard (CNS) A4 specification (210X297)) • 25-538398 A7 B7 V. Description of the invention) (Please read the description on the back first) Note: Please fill in this page again), (1) and (T), and the original image data shown in Figure 4 (1) is converted into the image data column shown in Figure 4 (2). That is, the image data shown in Fig. 4 (2) is supplied to the input data line of the first latch circuit 41. In FIG. 4 (2), the bit data d (i, j) shows the sub-pixels related to the i-th signal line Sli and the j-th scan line GL. As can be clearly understood from Fig. 4 (1) and (2), 1 pixel is 4-bit data, and the 4-bit data is divided into 1-line data for every 4 consecutive lines. For example, taking the pixel [1, 1] composed of the sub-pixel (1, 1), the sub-pixel (1, 2), the sub-pixel (1, 3), and the sub-pixel (1, 4) as an example, it is divided into The bit data d (l, l) of the sub-pixel (1,1) is in the first connection data row, the bit data d (1,2) of the sub-pixel (1,2) is in the second connection data row, The bit data d (1,3) of the sub-pixel (1,3) is in the third connection data row, and the bit data d (l, 4) of the sub-pixel (1,4) is in the fourth connection data row. It is regarded as bit data No. 1 in each of the first to fourth connection data rows. As mentioned above, the division of the 4-bit image data of a unit pixel can also be performed on other unit pixels. First, "when the image data shown in Fig. 4 (2) is supplied on the input data line", the synchronous latch pulses are sequentially output by the shift register 40. Therefore, each metadata of the first connection data is sequentially blocked by the first blocking circuit 41. In this way, after the first connection data is blocked by the first blocking circuit 41, a blocking pulse is supplied to all the second blocking circuits 42 in common. Therefore, the connection data is blocked by the j-th blocking circuit 41 and the second blocking circuit 42 and is output to the liquid crystal display section 10 through the signal line SL. In synchronization with this, the first scanning line GL1 is selected. Therefore, the first connection data is written in each sub-pixel electrode connected to the first scanning line GL1. Then, write the second connection data, the third connection data, and the fourth connection data in the same operation. Then, after the fourth connection data is written (that is, -26.538398 A7 B7) V. Invention Explanation “After the writing of the unit pixel in the first column is completed) As shown in FIG. 6 (a), the compensation voltage is shifted to the high potential side through the voltage control capacity wiring 32. Therefore, the pixel electrode potential of the unit pixel belonging to the first column It is adjusted to a predetermined potential. The result is that the unit pixel belonging to the first column is applied with the positive electrode potential Vcom in a positive polarity. At this time, when the pixel [1, 1] is focused on, the writing is performed by the first connection.

With this, the pixels [ι, ι] are displayed with a level 1 brightness in 16 gray scales. Also, for example, bit data d (l, l) = “1”, bit data d (l, 2) = “1”, bit data (1 (1,3) = “0”, bit data < 1 (1,4) = “0”, only the sub-pixel (1,1) and sub-pixel (1,2) are ON, and the sub-pixel (1,3) and sub-pixel (1,4) are OFF.

This prevents flicker. Of course, as in Implementation Mode 3 described below, it is also possible to individually set the storage capacity section to be routed to each pixel, and to reverse drive every 1 connection (every pixel), but the use of the capacity combined drive method is accompanied by the capacity combination The linearity of the Y characteristic becomes worse.

Description of the Invention ^ A liquid crystal display device having a color display of R (red), G (green), B (blue) sub-pixels can also be applied to the present invention. For liquid crystal display devices suitable for full-color display, the unit pixels 15 · 15 · 15 are regarded as sub-pixels of RGB, and the unit pixels 15 · 15 · 15 are used to form 1 pixel. The unit pixels arranged horizontally are divided into RGB pixels. Subpixels may be sufficient. In the liquid crystal display device of the full-color display structure having the above structure, the number of wiring connections is not increased as in the second conventional example. This can solve problems such as an increase in the number of connection pins and a decrease in image quality, such as display defects, caused by the rapid increase in the number of connection pins in the second conventional example. In the following, the LCD panel corresponding to VGA (640M80XRGB pixels) is taken as an example to illustrate. First, comparing the second conventional example and the non-area gray scale general full color display liquid crystal display device, the second conventional example is that the signal lines are routed to each pixel, and the scan lines are commonly routed to all the sub-pixels. Wiring structure, compared to the above-mentioned general full color liquid crystal display device, the number of connection pins increased by 640x RGBx 3 = 5760 (bar). In this way, according to the present invention, the increase in the number of connection pins can be suppressed to a considerable degree compared with the second conventional example, so that the increase in the number of defective connections caused by the rapid increase in the number of pins in the second conventional example can be solved. Problems such as image quality degradation due to display defects.

Description of the invention) (1) Optimization of the voltage control capacity section (please read the precautions on the back before filling this page) In the liquid crystal display device of the second aspect, the voltage control capacity portion Cc is determined by the following first expression.

Cc= { ( Vbias/Vepp-Vbias) } · ( Clc+Cgd) ...(1) 在此，Veep係補償電壓之振幅，Vbias係補償電壓之變化所致之像素電壓之變化量，Clc係每一次像素電極之液晶容量，Cgd係電晶體之寄生容量部。以下，就上述第1式之導入加以說明。驅動液晶時 Vbias係液晶之最小電壓振幅Vspp，而形成第7圖所示之範圍。然後，如本發明般之容量結合驅動方式係由電壓控制容量部之一方之電極施加補償電壓Veep，而可在信號線上如液晶之振幅電壓（Vspp)般設定必要之振幅。藉此，vbias 係形成Vbias: { Cc/(C1 c+Cgd) }· Veep。將該式加以變形而導出第1式。藉此，電壓控制容量部設定為第1式之Cc 時，可將液晶加以適當地驅動。但，若考慮到實際之製造機器，若儲存容量由Cc之0·6倍至1.4倍間之值，則將發揮充分之效果。在此，假設將電壓控制容量部設定成任意之值，則會產生以下之問題。即，將CC設為任意之值，則Vbias左右位移，且例如朝右側位移時如第8圖所示在a、B間振動，且將不顯示白色。相反地’若朝左側位移則不夠黑。即，無法獲知最佳之對比。當然’第8圖為正常白色之狀態時，正常黑色之狀態係依Vbias之左右移動產生與上述相反之現象。另一方面，若將振幅擴大則可解決相關之問題，但本紙張尺度適用中國國家標準（CNS) A4規格（210X297公爱） -30- 538398 A7 B7 五、發明説明（28 ) 消費電力將變大。在此，預先設定電壓控制容量部之值以滿足上述第1式，將可以少消費電力、最小振幅獲得充分之對比。又，藉如上述般將電壓控制容量部設定成最佳值，而亦可發揮以下之效果。即，Cc過小時漏電電流增大。另一方面，Cc過大時藉電壓控制容量部用之電極面積之增大而開口率將變小。藉此，如上述般預先設定成最佳值之〇.6 倍至1 ·4倍間之值，則可完成抑制漏電電流增大且高開口率之液晶顯示裝置。 (2)掃描信號之電壓振幅Vgpp之最適化本實施態樣2之液晶顯示裝置中，掃描信號之電壓振幅Vgpp係藉以下之第2式而決定。Cc = {(Vbias / Vepp-Vbias)} · (Clc + Cgd) ... (1) Here, Veep is the amplitude of the compensation voltage, and Vbias is the change amount of the pixel voltage caused by the change in the compensation voltage. Clc is Each time the liquid crystal capacity of a pixel electrode, Cgd is a parasitic capacity portion of a transistor. The introduction of the first formula will be described below. When driving the liquid crystal, Vbias is the minimum voltage amplitude Vspp of the liquid crystal, and forms the range shown in FIG. Then, in the capacity-combined driving method like the present invention, the compensation voltage Veep is applied from one of the electrodes of the voltage control capacity section, and the necessary amplitude can be set on the signal line like the amplitude voltage (Vspp) of liquid crystal. With this, vbias forms Vbias: {Cc / (C1 c + Cgd)} · Veep. This equation is modified to derive the first equation. Accordingly, when the voltage control capacity section is set to Cc of the first formula, the liquid crystal can be appropriately driven. However, if the actual manufacturing equipment is taken into consideration, if the storage capacity ranges from 0.6 to 1.4 times Cc, it will have a sufficient effect. If the voltage control capacity portion is set to an arbitrary value, the following problems occur. That is, if CC is set to an arbitrary value, Vbias is shifted left and right, and when it is shifted to the right, for example, it vibrates between a and B as shown in FIG. 8, and white is not displayed. Conversely, 'is not black enough if it is shifted to the left. That is, the best contrast cannot be known. Of course, when Fig. 8 is a state of normal white, a state of normal black causes the opposite phenomenon as described above according to the movement of Vbias. On the other hand, if the amplitude is enlarged, the related problems can be solved, but this paper size applies the Chinese National Standard (CNS) A4 specification (210X297 public love) -30- 538398 A7 B7 V. Description of the invention (28) Power consumption will change Big. Here, the value of the voltage control capacity section is set in advance to satisfy the above-mentioned first formula, so that sufficient power can be consumed and the minimum amplitude can be sufficiently compared. Further, by setting the voltage control capacity section to the optimum value as described above, the following effects can be exhibited. That is, when Cc is too small, the leakage current increases. On the other hand, when Cc is too large, the area of the electrode used by the voltage control capacity section increases and the aperture ratio becomes small. Accordingly, a liquid crystal display device having a high aperture ratio while suppressing an increase in the leakage current can be completed by setting the value between 0.6 times and 1.4 times the optimal value in advance as described above. (2) Optimization of the voltage amplitude Vgpp of the scanning signal In the liquid crystal display device of the second aspect of the present embodiment, the voltage amplitude Vgpp of the scanning signal is determined by the following second formula.

Vgpp=Von+Vth+Vspp/2+Voffset+Vlc+Voff“.(2) 在此，令開邊界為Von、關邊界為Voff、TFT之門播值為Vth、液晶之最小振幅為vspp、停止設定電壓為 Voffset(影像信號中心及相對電壓之差）、液晶之〇\電壓為Vic。且，考慮製造時之邊界，上述掃描信號之電壓振幅被設定為第2式所計算出之Vgpp之0.6倍至1.4倍間之值。因此，可藉可寫入之電壓範圍内最小之電壓振幅之掃描信號進行掃描，且可進行消費電力之減低。以下，參照第9圖以說明第2式之導入。且，第9圖中 Vsc係顯示信號中心。首先，對液晶驅動要求必要之閘振幅。為更容易進行了解，而將電位較影像信號中心值Vsc高之部分為Vg〇n、 (請先閲讀背面之注意事項再填寫本頁) .裝— '、一叮| •線， -31· 538398 A7Vgpp = Von + Vth + Vspp / 2 + Voffset + Vlc + Voff ". (2) Here, let the open boundary be Von, the close boundary be Voff, the TFT gate broadcast value be Vth, the minimum amplitude of the liquid crystal be vspp, stop The set voltage is Voffset (the difference between the center of the video signal and the relative voltage), and the voltage of the LCD is 0. Also, considering the boundary at the time of manufacture, the voltage amplitude of the scan signal is set to 0.6 of Vgpp calculated by the second formula. The value can be doubled to 1.4 times. Therefore, scanning can be performed by the scan signal with the smallest voltage amplitude in the writable voltage range, and the power consumption can be reduced. Hereinafter, the introduction of the second formula will be described with reference to FIG. 9 And, Vsc is the signal center shown in Figure 9. First, the necessary gate amplitude is required for liquid crystal driving. For easier understanding, the part whose potential is higher than the center value Vsc of the video signal is Vg0n, (please first Read the notes on the back and fill out this page).

Vgon=Vspp/2+Vth+Von ....(4) Vgoff=Voffset+Vlc+Voff".(5) 由第3式及第4式可導入第2式。然後，將掃描線號之電壓振幅設定成上述第2式所計算出之vgpp以下之值時’形成門檻值電壓Vth以下且無法啟動液晶。另一方面，設定成Vgpp以上之值時則可啟動液晶，但就消費電力之觀點而言並不適當。在此，由採用容量結合驅動方式之本發明可了解，若設定成上述第2式所計算出之電壓振幅，則可以最小電壓振幅且驅動液晶。如上述，可以最小振幅驅動掃描信號振幅Vgpp，而可進行消費電力之減低。如此一來，本實施態樣2中使用搭配有面積灰階及容量結合驅動之驅動方式之液晶顯示裝置，係藉將電壓控制容量部加以最適化，且進行補償電壓之電壓振幅Vepp及閘信號振幅Vgpp之最適化，而可一邊保持液晶之顯示等級，一邊以最小電壓振幅驅動液晶，且可大幅進行消費電力之減低。 (實施態樣1，2之補充事項） (1)上述實施態樣之液晶顯示裝置，係在穿透型、反射型之任一液晶顯示裝置中皆可適用。尤其，為反射型液衣紙張尺度適用中國國家標準（CNS) A4規格（210 X 297公釐）請先閲背之· 注意事項Vgon = Vspp / 2 + Vth + Von .... (4) Vgoff = Voffset + Vlc + Voff ". (5) Equations 2 and 3 can be introduced from equations 3 and 4. Then, when the voltage amplitude of the scanning line number is set to a value equal to or lower than vgpp calculated by the above formula 2, the threshold voltage Vth is formed and the liquid crystal cannot be activated. On the other hand, when the value is set to Vgpp or more, the liquid crystal can be activated, but it is not appropriate from the viewpoint of power consumption. Here, it can be understood from the present invention that adopts the capacity-combined driving method that if the voltage amplitude calculated by the above second formula is set, the liquid crystal can be driven with the smallest voltage amplitude. As described above, the scanning signal amplitude Vgpp can be driven with the smallest amplitude, and the power consumption can be reduced. In this way, in the second aspect of the present invention, a liquid crystal display device equipped with a driving method of area gray scale and capacity combined driving is used to optimize the voltage control capacity part and compensate the voltage amplitude Vepp and brake signal of the voltage The amplitude Vgpp is optimized, while maintaining the display level of the liquid crystal, the liquid crystal can be driven with the smallest voltage amplitude, and the power consumption can be greatly reduced.

The controller of this LCD panel is driven by the voltage of ι · 8ν 'and other signal voltages are designed at multiples of 1.8 V, and the design efficiency of the power supply becomes more favorable. In other words, Veep is set as a multiple of the reference voltage externally provided to represent the control voltage of the controller, and a high-efficiency DC / DC converter representing a supply pump can be used as a power circuit. This can reduce power consumption as a system. Next, the value of the bias voltage applied to the liquid crystal is determined according to the compensation voltage Vepp. This is determined by the voltage and transmittance characteristics of the liquid crystal, and if its value is set exactly at the center point where the transmittance changes as shown in Figure 18, the amplitude of the required signal voltage will become the smallest. In this embodiment, the value is set to 1.5V. Next, the value of the storage capacity formed between the previous scanning lines is determined. This value is determined by the signal line width of the scan electrodes. In this embodiment, the width of the scanning electrode is set to 6 μm, so the value of the storage capacity is set to 0.13 pF. Next, the value of the control capacity portion Cc is determined according to the following Equation 6.

It is obtained by substituting the liquid crystal capacity Clc determined by the value and the size of the pixel electrode into Equation 6. The design is performed to finally obtain the combination of cic, Cs, and Cc, and fill the capacity to meet the retention characteristics of the liquid crystal.

Therefore, all sub-pixels can be driven with the same bias voltage 'while maintaining sufficient retention characteristics in all sub-pixels. In addition, it is preferable to use a polycrystalline silicon thin film transistor as a scanning-side driving circuit of a dynamic matrix substrate, a functional element of a signal-side driving circuit portion, and a switching element of an image display portion. Therefore, the miniaturization of the transistor in the sub-pixel can be formed, and the design will be easier. In addition, the driving circuit can be easily built in the dynamic matrix substrate, which contributes to cost reduction and miniaturization. And 'The above example is constituted by dividing a pixel into a plurality of sub-pixels, and each sub-pixel meets the conditions shown in Table 2 above, but the above-mentioned voltage control capacity applies to the paper standard of China National Standard A4 (21〇 > < 297 mm) -40- 538398 A7 B7 V. Description of the invention (38) The method of optimizing the value of the measurement unit can also be applied to general unit pixels with non-subpixel structure. In addition, when this structure is applied to a reflective panel, the storage capacity and the control capacity can be designed without being aware of the aperture ratio, so it is suitable for the structure. These special structures can be implemented independently or in combination.

According to the above structure, the generation of fixed patterns generated by the area grayscale display can be minimized. The inventor of the present application has conducted research in order to solve the generation of fixed patterns in the conventional examples.

Explanation of the invention (50) The above result is caused by the following reasons. Figure 29 (B), (C) does not produce a fixed image, it is borrowed by sub-pixels. The display image is made into] a glyph image and a concentric circle image, so that the center of gravity of the area is almost consistent. In addition, grayscale inversion occurs in Fig. 29 (B), but it does not occur in Fig. 29 (C). The reason for the grayscale inversion is] only the area grayscale in the zigzag image is performed in the first dimension (upper and lower directions of the original shadow), but the concentric circle image is performed in the second dimension (upper and lower directions of the original shadow and left and right). The gray scale of the area. Therefore, the display image of the best sub-pixel can be evaluated as a concentric circle image. In the above simulation test, the evaluation is: a π-shaped image and a concentric circle image, but the types can be evaluated differently by the above method. Sub-pixel display image.

(Please read the precautions on the back before filling in (This page) (4) When the unit pixel is divided to form a sub-pixel as in the present invention, the pixel becomes smaller, so the control capacity of the smallest pixel becomes smaller. Therefore, the pixel electrode potential variation caused by leakage current, etc., becomes larger. In order to compensate for the change, it can also be regarded as a structure with another storage capacity. (Implementation mode 16) Figure 30 is a circuit diagram of the liquid crystal display device of this embodiment mode 16, and Figure 31 shows the structure of a unit pixel. Structured circuit diagram. The same reference numerals are attached to the parts corresponding to the implementation aspect 1, and detailed explanations are omitted. In the aspect 16 of this embodiment, the display generated by the interleave driving is performed. And the configuration of the sub-pixels P1 to P4 constituting the unit pixel is arranged in the order of P1, P2, P3, and P4 from top to bottom in the above-mentioned implementation form 1, but in the implementation form 16 according to P1, P3, and P2 , P4 order configuration. As a result, the area ratio of the pixel electrode is the area of the sub-pixel electrode M1: the area of the sub-pixel electrode M2: the area of the sub-pixel electrode M3 · the area of the sub-pixel electrode μ 4 = 1: 2: 4: 8. Then, the first-bit data of the 4-bit image data corresponds to the sub-pixel ρ 丨, and the second-bit data corresponds to the sub-pixel ρ 3, and the third-bit data corresponds to the sub-pixel ρ 3. The 4-bit data corresponds to the sub-pixel P4. In addition, the voltage control capacity is also intended to form a corresponding capacity value, and the value of the voltage control capacity C1 is set: the value of the voltage control capacity C2: the value of the voltage control capacity C3: the value of the voltage control capacity C4 = 1: 2: 4: 8. Here, the liquid crystal display device in the aspect 16 of the present embodiment has two voltage control capacity wirings 32a, 32b wired on the unit pixel 15.

In addition, the display of the image data of the odd lines and the display of the image data of the even lines are performed by reading the image data stored in the frame memory 60 as shown in FIG. 32. That is, the image data to be displayed on one frame of the frame memory 60 is stored, and the controller 13 is configured to give the control signal X for reading out the image data of the odd rows to the φzhen memory during the period of the shadow plane a. 60, and the control signal γ for reading the image data of the even-numbered lines is passed to the frame memory 60 during the period of the shadow plane B.

Into. Then, when the writing of the sub-pixels on the first line is completed, the third scanning line is selected as shown in FIG. 33 (c). Therefore, the sub-pixel (corresponding to the sub-pixel p2 of the third line) connected to the third scanning line of the video signal is written. Then, after the writing of the sub-pixels in the third row is completed, the compensation voltage signal is shifted to the high potential side as shown in FIG. 33 (e). Therefore, the sub-pixel electrodes M1, M2 will pass through the first! The capacity line 3 is controlled so as to be adjusted to a predetermined potential. This result is that voltages are applied to the sub-pixels P1 and P2 in the first and third rows with a positive polarity. And, the compensation voltage signal that is shifted toward the high potential side is maintained in a high potential state until the next shadow plane A is shifted toward the low potential side. Moreover, the timing chart of only one unit pixel is drawn in FIG. 31, but it reaches the unit pixels composed of the fifth to eighth rows, the unit pixels composed of the ninth to twelfth rows, ..., and is located at the bottom Up to the unit pixel, the same operations as those of the unit pixels formed in the first to fourth rows are performed.

Then, when the writing of the sub-pixels on the second line is completed, the fourth scanning line is selected as shown in FIG. 33 (d). Therefore, writing is performed on the under-pixels (equivalent to the sub-pixel P4 on the fourth line) connected to the fourth scanning line of the video signal. Then, after the writing of the sub-pixels in the fourth row is completed, the compensation voltage signal is shifted to the low potential side as shown in FIG. 33 (f). Therefore, the sub-pixel electrodes M3 and M4 are adjusted to a pre-electric potential through the second control capacity line 32b. This result is that voltages are applied to the sub-pixels p3 and p4 in the second and fourth rows with a negative polarity. The compensation voltage signal shifted to the low potential side is maintained in a high potential state until the next shadow plane B is shifted to the low potential side.

Next, the switching operation of stepwise jog and interleave driving will be described. When the identification signal S for identifying the still picture display or the animation display is given by the controller 13, the controller 13 performs a control action corresponding to the identification signal S. That is, when the identification signal S is displayed during the daytime display, the controller 13 reads out the frame memory 60, controls the selection sequence of the scan-side drive circuit 11, and compensates the drive circuit 31 for applying a compensation voltage as if it were interleaved driving. Control of voltage change timing, etc. Therefore, the display produced by the interlaced driving can be achieved. When the identification signal S is displayed as an animation, the controller 13 reads out the frame memory 60, controls the selection sequence of the scan-side drive circuit 11, and compensates the drive circuit 3 for applying a compensation voltage as if it were driven step by step. Control of voltage change timing, etc. As a result, the display produced by the stepwise drive can be achieved.
