The LCD panel 5 is in the data signal line. Material signal and scanning signal, line ^ 1 scanning signal line ^ points are provided with pixel areas 夕, and the pixel data signal ^ 1 is supplied to the pixel area selected from all pixel areas by the scanning signals S4_1 to S4_n, to Display the image. For the operation of the type 2 LCD, the image input signal lin and the clock signal S2 are input to the control cry with reference to the timing chart shown in FIG. 6 "like the data signal Sla, the input pulse Slb, the clock signal / S; aUS ... from the controller 1 output.

Pixel data signal field, and display corresponding to The selected pixels are 501357. 5. The image of the invention description (3). However, the conventional LCD has the following problems. Figure 7 illustrates that the number of scanning signals XI to Xn is 1 200, and the image input signal I i η When the number of scan lines in the image display area (image display period) is 1 0 0 0 and the total number of scan lines is 11 2 5, the operation diagram of the conventional LCD monitor is shown in Figure 7. As shown in FIG. First in display area (during image display) The pixel data signals S3-1 to S3-m are first written on the LCD panel 5. The scanning signal is S4-1. The output enable signal S1 d is directly in the active mode. Then, the input pulse S1 b and the clock signal Sic are Synchronized shifting, and pixel data signals S3-1 to S3-m of the second line are written to the LCD panel 5. In this way, from the first line to the 1 080th line, the pixel data signals S3-1 to S3 -m are all written on the LCD panel 5. The state [2] shows the pixel data signals 53-1 to S3-ni of the 1 080th line when they are written to the LCD panel 5 and the scanning signal is 54-1080. Then, when the clock signal Sic is received, a blank area (black band) is written. The blank area (blank period) includes 45 lines, and the LCD panel 5 becomes black in the blank area. The status [3] is displayed below When one line is 11 2 6, that is, when the next line will return to the first line, the scanning signal of the first line is S4-1 and the scanning signal of the 1126 line is S4-1126. Therefore, regarding the first For 1126 lines and the following lines, the pixel data signals S3-1 to S3-m will be similarly written on the fifth line to 1125 The state [4] of Example 5 in which a liquid crystal display panel 5 shown
观357 五、發明說明（4) ，空白區域的開始視為影像顯示區域的開始之狀態。於狀 I、[4]中，黑色部分顯示空白區域5a和空白區域5c， 而白色部分則為影像顯示區域5b。如狀態[4 ]所顯示， 空白區域5a和空白區域5c皆寫在影像顯示區域5b之 上方和下方’而另一影像顯示區域5d則顯示在下方之空 白區域5 c。因此’其中出現一問題便是不能在影像顯示 區域上方和下方寫完全的空白區域。Viewing 357 V. Description of the Invention (4), the beginning of the blank area is regarded as the beginning of the image display area. In states I and [4], the black part shows the blank area 5a and the blank area 5c, and the white part is the image display area 5b. As shown by the state [4], the blank area 5a and the blank area 5c are both written above and below the image display area 5b 'and the other image display area 5d is displayed below the blank area 5c. So one of the problems is that you ca n’t write a complete blank area above and below the image display area.
為解決此一問題，當掃描訊號線X1至Χη的數目大 於垂直周期的掃描線總數時，便使用對於影像輸入訊號 Ι^η施以數位訊號處理的技術。例如，當液晶面板&之 掃描訊號線X1至χη的數目是1 2 〇 0，影像顯示區域之 影像輸入訊號Π η的掃描線數目是1 〇 8 〇，而掃描線之 ，數是11 2 5時；將影像輪入訊號I i η儲存於幀記憶體。 藉此操作，而進行影像顯示期間之掃描線數目保持在 iOSO ’而掃描線總數為ι2〇〇的液晶顯示。 但是，當掃描線總數因執行此數位處理而增加時，就 會產生幘記憶體和幀記憶體控制器等元件增加，且構造變 传複雜且龐大的問題。 再者，日本專利公報第282006 1號揭露一種液晶面 板’係使用多晶矽技術，其中提議將一複雜之掃描訊號電 路設置於液晶面板中，藉由令多數之掃描訊號處於現用模 式的方式，而達到將完全的空白區域寫入於影像顯示區域 之上方和下方。然而，構成目前主流之採用非晶矽的液晶 面板之技術，若將之與使用多晶矽技術之液晶面板相較，To solve this problem, when the number of scanning signal lines X1 to Xη is larger than the total number of scanning lines of a vertical period, a digital signal processing technique is applied to the image input signal I ^ η. For example, when the number of scanning signal lines X1 to χη of the LCD panel & is 1 2 0 0, the number of scanning lines of the image input signal Π η in the image display area is 1 0 0 0, and the number of scanning lines is 11 2 At 5 o'clock, the image wheel-in signal I i η is stored in the frame memory. With this operation, the number of scanning lines during the image display period is kept at iOSO ′ and the total number of scanning lines is ι200. However, when the total number of scan lines is increased due to the execution of this digital processing, problems such as increase in components such as memory and frame memory controllers, and complicated and large-scale structural changes will occur. Furthermore, Japanese Patent Gazette No. 282006 1 discloses a type of liquid crystal panel using polycrystalline silicon technology, in which a complex scanning signal circuit is proposed to be arranged in the liquid crystal panel, so that most of the scanning signals are in an active mode to achieve Write a completely blank area above and below the image display area. However, if the technology that constitutes the current mainstream liquid crystal panel using amorphous silicon is compared with the liquid crystal panel using polycrystalline silicon technology,

[Summary of the Invention] As described above, the device of the present invention uses an amorphous silicon circuit to maintain the conventional structure even when the number of scanning signal lines is larger than the total number of trace lines. In the case, the image is displayed above and below the area. According to the first embodiment of the present invention, the purpose is to provide a liquid crystal display image signal in a vertical period sweep technology, which can still be written on the liquid crystal panel while scanning the signal element of the two kings to provide a liquid crystal display, Package image data; ΪΠ: Most of the data signal lines are used to input the scanning signal lines of the evening, ~, and evening, and the scanning signals are used to input the scanning signals; the 31 i element area is arranged on the data signal lines and the scanning signals The intersection of the lines ρ ^ and 耆 supplies the image data signal to the pixel area selected from the pixel area by the scanning signal to display the image display signal circuit corresponding to the image data signal, and transmits the signal to the data according to the image input signal Signal line; sweep signal circuit, used to input the input signal used to generate the scanning signal =, so that it moves in synchronization with the clock signal, and the output indicates that the signal is input ^ send 4 input pulses to the scanning signal line as the Scanning signal

Description of the invention (15) S13-m; The scanning signal circuit 14 and the clock signal S21c output the scanning signal S14-k and the scanning signal S14- (k + l) in sequence in synchronization with each other. As a result, the same pixel data signals S13-1 to S13-in are written into the two-line LCD panel 15 so that the image is enlarged. At this time, the output enable signal S2 1 d is not always in the active mode, and the pulse width is made into a narrow frequency, and the pixel data signals S13-1 to SI 3i are written at the first writing time and the second writing time. The pulse widths of time are similar. In this way, when the pixel data signals S13-1 to S13-in are raised, the speed of the input data signal lines Y1 to Ym will be slowed down, so that the pixel data signals S13-1 to S13-m will not cause brightness. difference. The other operations are similar to those of the first embodiment. As described above, according to the second embodiment, the controller 21 outputs the clock signal S21C to the pixel data signal S13 of a line twice to 3m, and the scanning signal circuit 14 and the clock signal S2 ic are simultaneously pressed. Scan signals S14-k and S14_ (k + 1) are output in sequence. When the control signal is input to the image, the signal is half or less of the scanning signal line of the scanning panel 15 in the vertical period. The control write 21 outputs the clock signal S21c twice, and the output signal is synchronized with the clock signal S2U. ^ Called one in order (K + 1); therefore, the image = the sign S14-k and the scan signal image above and below the display area, and the blank line area is written in the film clearly, this = = = made. For example, the LCD panel is not limited to the active matrix type.
