請參閱第4圖,第4圖為第1圖所示之調整電路104產生調整後之水平遮沒間隔資料的第一實施例的示意圖。於此一實施例中,調 整電路104所調整的掃描線係對應至顯示螢幕102所顯示之有效顯示區域AA中的最後一條掃描線L_I(若有效顯示區域AA的解析度為1920x1080,則調整電路104所調整的掃描線即為對應至有效顯示區域AA的第1080條掃描線),因此,除了原本的水平遮沒間隔資料D_HBI_L_I,調整後之水平遮沒間隔資料另包含了新增的水平遮沒間隔資料D_HBI_L__I’,換言之,調整後之水平遮沒間隔資料係為D_HBI_L_I+D_HBI_L_I’,因此,新增的水平遮沒間隔資料D_HBI_L_I’可視為原本的水平遮沒間隔資料D_HBI_L_I之延伸的水平遮沒間隔資料,因此,藉由新增的水平遮沒間隔資料D_HBI_L_I’,可加速其他資料的傳輸,如此一來,由於對應有效顯示區域AA的有效顯示資料可由輸出電路106提早完成傳送至顯示螢幕102,因而使得顯示螢幕102(例如液晶顯示螢幕)有更充裕的時間完成整個影像畫面的穩定顯示,進而大幅提升畫質。Please refer to FIG. 4, which is a schematic diagram of the first embodiment in which the adjustment circuit 104 shown in FIG. 1 generates the adjusted horizontal blanking interval data. In this embodiment, the tone The scan line adjusted by the whole circuit 104 corresponds to the last scan line L_I in the effective display area AA displayed on the display screen 102 (if the resolution of the effective display area AA is 1920×1080, the scan line adjusted by the adjustment circuit 104 is In order to correspond to the 1080th scan line of the effective display area AA, therefore, in addition to the original horizontal blanking interval data D_HBI_L_I, the adjusted horizontal blanking interval data additionally includes a new horizontal blanking interval data D_HBI_L__I', in other words The adjusted horizontal blanking interval data is D_HBI_L_I+D_HBI_L_I'. Therefore, the newly added horizontal blanking interval data D_HBI_L_I' can be regarded as the horizontal blanking interval data of the extension of the original horizontal blanking interval data D_HBI_L_I, therefore, The transmission of other data can be accelerated by the newly added horizontal masking interval data D_HBI_L_I', so that the effective display data corresponding to the effective display area AA can be transmitted to the display screen 102 early by the output circuit 106, thereby causing the display screen 102 to be displayed. (such as the LCD screen) has more time to complete the stable display of the entire image, and then Enhance the quality pieces.
請參閱第5圖,第5圖為增加水平遮沒間隔資料以使得完整影像畫面之有效顯示資料可提早完成傳送的操作示意圖。於第5圖的附圖(A)中,由於沒有採用本發明的驅動機制來增加任何掃描線的水平遮沒間隔資料,因此,完成一張完整畫面的驅動時間可簡單表示如下:FT =T AA +T HBI +T VBI (1)Please refer to Fig. 5. Fig. 5 is a schematic diagram of the operation of adding the horizontal blanking interval data so that the effective display data of the complete image picture can be completed early. In the drawing (A) of Fig. 5, since the driving mechanism of the present invention is not used to increase the horizontal blanking interval data of any scanning line, the driving time for completing a complete picture can be simply expressed as follows: FT = T AA + T HBI + T VBI (1)
於上述方程式(1)中,FT 代表單一完整影像畫面進行驅動所需的時間,而T AA 則代表輸出電路106傳送完整影像畫面之有效顯示區域AA的有效顯示資料至顯示螢幕102所需的時間,T HBI 代表輸出電路106傳送對應水平遮沒間隔區域HBIAA 及HBIVBI 之水平遮沒間隔資料至顯示螢幕102所需的時間,以及T VBI 代表輸出電路106傳送對應垂直遮沒間隔區域VBI之垂直遮沒間隔資料至顯示螢幕102所需的時間。In the above equation (1), FT represents the time required for driving a single complete image frame, and T AA represents the time required for the output circuit 106 to transmit the effective display data of the effective display area AA of the complete image frame to the display screen 102. T HBI represents the time required for the output circuit 106 to transmit the horizontal blanking interval data corresponding to the horizontal blanking interval areas HBI AA and HBI VBI to the display screen 102, and the T VBI representative output circuit 106 transmits the corresponding vertical blanking interval area VBI. Vertically masks the interval data to the time required to display the screen 102.
於第5圖的附圖(B)中,由於採用了本發明的驅動機制而增加了顯示螢幕102所顯示之有效顯示區域AA中的最後一條掃描線L_I的水平遮沒間隔資料,因此,完成一張完整畫面的驅動可簡單表示如下:In the drawing (B) of FIG. 5, since the horizontal masking interval data of the last scanning line L_I in the effective display area AA displayed on the display screen 102 is increased by the driving mechanism of the present invention, the completion is completed. A complete picture of the driver can be simply expressed as follows:
FT =T AA '+T HBI '+T VBI ' (2) FT = T AA '+ T HBI '+ T VBI ' (2)
於上述方程式(2)中,T AA '則代表輸出電路106傳送完整影像畫面之有效顯示區域AA的有效顯示資料至顯示螢幕102所需的時間,T HBI '代表輸出電路106傳送對應水平遮沒間隔區域HBIAA 及HBIVBI 之原本的水平遮沒間隔資料以及新增的水平遮沒間隔資料D_HBI_L_I’至顯示螢幕102所需的時間,以及T VBI '代表輸出電路106傳送對應垂直遮沒間隔區域VBI之垂直遮沒間隔資料至顯示螢幕102所需的時間。In the above equation (2), T AA ' represents the time required for the output circuit 106 to transmit the effective display data of the effective display area AA of the complete image frame to the display screen 102, and the T HBI 'represents the output circuit 106 to transmit the corresponding horizontal mask. The original horizontal blanking interval data of the interval areas HBI AA and HBI VBI and the new horizontal blanking interval data D_HBI_L_I' to the time required to display the screen 102, and the T VBI 'representing the output circuit 106 to transmit the corresponding vertical blanking interval area The VBI vertically masks the interval data to the time required to display the screen 102.
由第5圖可清楚得知,在同一完整影像畫面的驅動時間FT 之下,當輸出電路106需額外傳送新增的水平遮沒間隔資料D_HBI_L_I’時,則輸出電路106會利用較大的傳輸頻寬來傳送資料,因此,T AA '會小於T AA (亦即T AA '<T AA ),換言之,相較於習知的驅動機制,本發明的驅動機制會讓有效顯示資料提早完成傳送,因此允許顯示螢幕102(例如液晶顯示螢幕)有更加充裕的時間來讓影像畫面的顯示輸出達到穩定。As is clear from FIG. 5, under the driving time FT of the same full image picture, when the output circuit 106 needs to additionally transmit the new horizontal blanking interval data D_HBI_L_I', the output circuit 106 utilizes a larger transmission. The bandwidth is used to transmit data. Therefore, T AA 'is less than T AA (ie, T AA '< T AA ). In other words, the driving mechanism of the present invention allows the effective display of data to be transmitted earlier than the conventional driving mechanism. Therefore, the display screen 102 (for example, a liquid crystal display screen) is allowed to have more time to stabilize the display output of the image frame.
於第4圖所示之實施例中,調整電路104僅對單一掃描線(亦即掃描線L_I)的水平遮沒間隔資料進行調整(增加),然而,此僅作為範例說明,而非本發明的限制。請參閱第6圖,第6圖為第1圖所示之調整電路104產生調整後之水平遮沒間隔資料的第二實施例的示意圖。調整電路104亦可對複數條掃描線的水平遮沒間隔資料進行調整,舉例來說,調整電路104所調整的掃描線對應至顯示螢幕102所顯示之有效顯示區域AA中的第一條掃描線L_0以及最後一條掃描線L_I,因此,除了原本的水平遮沒間隔資料D_HBI_L_0、D_HBI_L_I,調整後之水平遮沒間隔資料另包含了新增的水平遮沒間隔資料D_HBI_L_0’、D_HBI_L_I’。同樣地,由於新增的水平遮沒間隔資料D_HBI_L_0’、D_HBI_L_I’,輸出電路106會利用較大的傳輸頻寬來傳送資料,因而達到讓有效顯示資料提早完成傳送的目的。In the embodiment shown in FIG. 4, the adjustment circuit 104 only adjusts (increases) the horizontal blanking interval data of a single scanning line (that is, the scanning line L_I), however, this is merely an example, not the present invention. limits. Please refer to FIG. 6. FIG. 6 is a schematic diagram of a second embodiment of the adjustment circuit 104 shown in FIG. 1 for generating the adjusted horizontal blanking interval data. The adjusting circuit 104 can also adjust the horizontal blanking interval data of the plurality of scanning lines. For example, the scanning line adjusted by the adjusting circuit 104 corresponds to the first scanning line in the effective display area AA displayed on the display screen 102. L_0 and the last scan line L_I, therefore, in addition to the original horizontal blanking interval data D_HBI_L_0, D_HBI_L_I, the adjusted horizontal blanking interval data further includes new horizontal blanking interval data D_HBI_L_0', D_HBI_L_I'. Similarly, due to the newly added horizontal masking data D_HBI_L_0' and D_HBI_L_I', the output circuit 106 uses a large transmission bandwidth to transmit data, thereby achieving the purpose of allowing the effective display of the data to be completed earlier.
於第4圖所示之實施例中,調整電路104僅增加對應至顯示螢幕102所顯示之有效顯示區域AA中的最後一條掃描線L_I的水平遮沒間隔資料,而對應至顯示螢幕102所顯示之有效顯示區域AA中的其他掃描線的水平遮沒間隔資料並未進行任何調整,同樣地,於第6圖所示之實施例中,調整電路104僅增加對應至顯示螢幕102所顯示之有效顯示區域AA中的第一條掃描線L_0與最後一條掃描線L_I的水平遮沒間隔資料,而對應至顯示螢幕102所顯示之有效顯示區域AA中的其他掃描線的水平遮沒間隔資料並未進行任何調整,然而,此僅作為範例說明,而非本發明的限制。請參閱第7圖與第8圖,第7圖為第1圖所示之調整電路104產生調整後之水平遮沒間隔資料的第三實施例的示意圖,以及第8圖為第1圖所示之調整電路104產生調整後之水平遮沒間隔資料的第四實施例的示意圖。於第7圖與第8圖所示之實施例中,調整電路104另會減少顯示螢幕102所顯示之有效顯示區域AA中的其他掃描線的水平遮沒間隔資料,如此一來,可允許新增的水平遮沒間隔資料D_HBI_L_0’、D_HBI_L_I’具有較大的資料量。這些設計上的變化均屬本發明的範疇。In the embodiment shown in FIG. 4, the adjustment circuit 104 only increases the horizontal blanking interval data corresponding to the last scan line L_I in the effective display area AA displayed on the display screen 102, and corresponds to the display of the display screen 102. The horizontal blanking interval data of the other scanning lines in the effective display area AA is not adjusted. Similarly, in the embodiment shown in FIG. 6, the adjusting circuit 104 only increases the effective corresponding to the display of the display screen 102. The horizontal scanning area of the first scanning line L_0 and the last scanning line L_I in the display area AA is blank, and the horizontal blanking interval data corresponding to the other scanning lines in the effective display area AA displayed on the display screen 102 is not Any adjustments are made, however, this is by way of example only and not as a limitation of the invention. Please refer to FIG. 7 and FIG. 8. FIG. 7 is a schematic diagram of a third embodiment of the adjustment circuit 104 shown in FIG. 1 for generating the adjusted horizontal blanking interval data, and FIG. 8 is a first FIG. The adjustment circuit 104 produces a schematic diagram of a fourth embodiment of the adjusted horizontal blanking interval data. In the embodiments shown in FIGS. 7 and 8, the adjustment circuit 104 further reduces the horizontal blanking interval data of the other scanning lines in the effective display area AA displayed on the display screen 102, so that new data can be allowed. The increased horizontal blanking interval data D_HBI_L_0', D_HBI_L_I' has a large amount of data. These design changes are within the scope of the invention.
於上述之第4圖、第6圖、第7圖與第8圖所示之實施例中,調整電路104所調整之掃描線均為對應至顯示螢幕102所顯示之有效顯示區域AA的掃描線,亦即上述實施例中的非水平遮沒間隔資料係為對應至有效顯示區域AA的有效顯示資料,然而,於其他實施例中,非水平遮沒間隔資料亦可以是對應至垂直遮沒間隔VBI的垂直遮沒間隔資料。In the embodiments shown in FIG. 4, FIG. 6, FIG. 7 and FIG. 8 above, the scan lines adjusted by the adjustment circuit 104 are all corresponding to the scan lines of the effective display area AA displayed on the display screen 102. That is, the non-horizontal blanking interval data in the above embodiment is the effective display data corresponding to the effective display area AA. However, in other embodiments, the non-horizontal blanking interval data may also correspond to the vertical blanking interval. VBI vertical blanking interval data.
請參閱第9圖,第9圖為第1圖所示之調整電路104產生調整後之水平遮沒間隔資料的第五實施例的示意圖。於此一實施例中,調整電路104所調整的掃描線係對應至顯示螢幕102中垂直遮沒間隔區域VBI的掃描線L_I+1~L_N,因此,除了原本的水平遮沒間隔資料HBIVBI ,調整後之水平遮沒間隔資料另包含了新增的水平遮沒間隔資料HBIVBI ’。簡而言之,新增的水平遮沒間隔資料HBIVBI ’可視為原本的水平遮沒間隔資料HBIVBI 之延伸的水平遮沒間隔資料,因此,藉由新增的水平遮沒間隔資料HBIVBI ’,同樣可加速其他資料的傳輸,由於對應有效顯示區域AA的有效顯示資料可由輸出電路106提早完成傳送至顯示螢幕102,因而使得顯示螢幕102(例如液晶顯示螢幕)有更充裕的時間完成整個影像畫面的穩定顯示。由於熟習技藝者可輕易地依據第5圖的相關說明而輕易地瞭解此一實施例增加對應垂直遮沒間隔區域VBI之水平遮沒間隔資料以使得完整影像畫面之有效顯示資料可提早完成傳送的操作原理,故於此便不另贅述。Please refer to FIG. 9. FIG. 9 is a schematic diagram showing a fifth embodiment in which the adjustment circuit 104 shown in FIG. 1 generates the adjusted horizontal blanking interval data. In this embodiment, the scan line adjusted by the adjustment circuit 104 corresponds to the scan lines L_I+1~L_N of the vertical blanking interval area VBI in the display screen 102. Therefore, in addition to the original horizontal blanking interval data HBI VBI , The adjusted horizontal blanking interval data also includes the new horizontal blanking interval data HBI VBI '. In short, the new horizontal occlusion interval data HBI VBI 'can be regarded as the horizontal occlusion interval data of the original horizontal occlusion interval data HBI VBI extension, therefore, with the new horizontal occlusion interval data HBI VBI ', the transmission of other data can also be accelerated, since the effective display material corresponding to the effective display area AA can be transferred to the display screen 102 by the output circuit 106 early, so that the display screen 102 (for example, the liquid crystal display screen) has more time to complete the whole. A stable display of the image. Since the skilled artisan can easily understand according to the related description of FIG. 5, this embodiment increases the horizontal blanking interval data corresponding to the vertical blanking interval area VBI so that the effective display data of the complete image frame can be completed early. The principle of operation, so it will not be repeated here.
於第9圖所示之實施例中,調整電路104僅增加對應至垂直遮沒間隔區域VBI的掃描線的水平遮沒間隔資料,而對應至顯示螢幕102所顯示之有效顯示區域AA的掃描線的水平遮沒間隔資料並未進行任何調整,然而,此僅作為範例說明,而非本發明的限制。請參閱第10圖,第10圖為第1圖所示之調整電路104產生調整後之水平遮沒間隔資料的第六實施例的示意圖。於第10圖所示之實施例中,調整電路104另會減少顯示螢幕102所顯示之有效顯示區域AA中的掃描線L_0~L_I的水平遮沒間隔資料,如此一來,可允許新增的水平遮沒間隔資料HBIVBI ’具有較大的資料量。In the embodiment shown in FIG. 9, the adjustment circuit 104 only increases the horizontal blanking interval data corresponding to the scanning line of the vertical blanking interval area VBI, and corresponds to the scanning line of the effective display area AA displayed on the display screen 102. The horizontal obscuration interval data is not adjusted, however, this is merely illustrative and not a limitation of the present invention. Please refer to FIG. 10. FIG. 10 is a schematic diagram showing a sixth embodiment of the adjusted horizontal blanking interval data by the adjusting circuit 104 shown in FIG. 1. In the embodiment shown in FIG. 10, the adjustment circuit 104 further reduces the horizontal blanking interval data of the scanning lines L_0 to L_I in the effective display area AA displayed on the display screen 102, so that the new addition can be allowed. The horizontal blanking interval data HBI VBI 'has a large amount of data.

Please refer to FIG. 13, which is a functional block diagram of a second embodiment of the image display system of the present invention. In the embodiment, the image display system 1300 includes, but is not limited to, a video display device 1302 and a stereo glasses 1304. The video display device 1302 includes the display screen 102, the output circuit 106, and the adjustment circuit 104 described above, and a backlight module 1306 that further includes a backlight required to provide a display screen (eg, a liquid crystal display screen) 102. The stereo glasses 1304 include, but are not limited to, a control circuit 1308, a left eyeglass lens 1310, and a right eyeglass lens 1312. The video display device 1302 is provided with stereo glasses 1304 to provide stereoscopic images to the user. The left eyeglass lens 1310 is for the user to view the left eye image frame, and the right eyeglass lens 1312 is for the user to view the right eye image frame. In addition, the control circuit 1308 is electrically connected to the left eyeglass lens 1310 and the right eyeglass lens 1312. For respectively outputting the control signals S1, S2 to the left eyeglass lens 1310 and the right eyeglass lens 1312, to control the left eyeglass lens 1310 to switch between the open state and the closed state and control the right eyeglass lens 1312 between the open state and the closed state Switch. For example, the stereo glasses 1304 are a pair of shutter glasses. Therefore, the left eyeglass lens 1310 and the right eyeglass lens 1312 are shutter lenses respectively, and each has a liquid crystal layer, and the control signals S1 and S2 can be control voltages for controlling the liquid crystal. The rotation of the liquid crystal cell in the layer is for the purpose of controlling the light transmittance. However, this is for illustrative purposes only and is not intended to be a limitation of the present invention. For example, any structure having light transmittance control can be used. The left eyeglass lens 1310 and the right eyeglass lens 1312 can be realized, and the purpose of controlling the left eyeglass lens 1310 and the right eyeglass lens 1312 to switch between the open state and the closed state can also be achieved. In addition, the stereo glasses 1304 are not limited to shutter glasses, and any stereo glasses that can be used with the video display device 1302 to view stereoscopic images and apply the stereoscopic image display mechanism disclosed by the present invention are all in accordance with the spirit of the present invention.
於本發明中,上述的「關閉狀態」是指左眼/右眼鏡片(例如快門鏡片)完全不透光(亦即光線穿透率為0%),因此,只要左眼/右眼鏡片並非是完全不透光(亦即光線穿透率並非為0%),便可視為處於「開啟狀態」,舉例來說,當快門鏡片全開(例如光線穿透率為100%)、半開(例如光線穿透率為50%)或者微開(例如光線穿透率為0.1%),快門鏡片便可視為處於開啟狀態。簡而言之,當左眼/右眼鏡片的光線穿透率大於0%(但小於或等於100%),則左眼/右眼鏡片便可視為進入開啟狀態。In the present invention, the above "closed state" means that the left eye/right eyeglass lens (for example, the shutter lens) is completely opaque (that is, the light transmittance is 0%), so that as long as the left eye/right eyeglass lens is not It is completely opaque (that is, the light transmittance is not 0%) and can be regarded as being "on". For example, when the shutter lens is fully open (for example, the light transmittance is 100%), it is half-open (for example, light). The shutter is 50%) or slightly open (for example, a light penetration of 0.1%), and the shutter lens can be considered to be on. In short, when the light transmittance of the left/right eyeglasses is greater than 0% (but less than or equal to 100%), the left/right eyeglasses can be considered to be in an open state.
立體眼鏡1304可供使用者配戴以觀看視訊顯示裝置1302透過顯示螢幕102所呈現的立體影像。舉例來說,於第1圖所示之實施例中,視訊顯示裝置1302可以是一液晶顯示器,因此,顯示螢幕102為一液晶顯示螢幕,而經由顯示螢幕102所產生的影像光輸出便經由立體眼鏡1304來控制是否可進入使用者的左眼或右眼。請注意,視訊顯示裝置1302並未限定是液晶顯示器,亦即,視訊顯示裝置1302亦可以是任何可跟立體眼鏡1304一併搭配使用以呈現立體影像予使用者的視訊輸出裝置,換言之,若立體眼鏡1304為快門眼鏡,則視訊顯示裝置1302便是可搭配快門眼鏡使用之任何的顯示器或投影機。The stereo glasses 1304 are available for the user to wear to view the stereoscopic image presented by the video display device 1302 through the display screen 102. For example, in the embodiment shown in FIG. 1, the video display device 1302 can be a liquid crystal display. Therefore, the display screen 102 is a liquid crystal display screen, and the image light output generated through the display screen 102 is transmitted through the stereoscopic image. Glasses 1304 are used to control whether the user's left or right eye can be accessed. Please note that the video display device 1302 is not limited to a liquid crystal display. That is, the video display device 1302 can also be any video output device that can be used together with the stereo glasses 1304 to present a stereoscopic image to the user. The glasses 1304 are shutter glasses, and the video display device 1302 is any display or projector that can be used with the shutter glasses.
對於立體眼鏡1304為快門眼鏡的範例,可藉由控制電路1308適當控制左眼鏡片1310與右眼鏡片1312於開啟狀態與關閉狀態之間進行切換,舉例來說,視訊顯示裝置1302可以藉由一訊號發射器(未顯示)來與立體眼鏡1304進行通訊,例如,立體眼鏡(例如快門眼鏡)1304可透過有線傳輸或無線傳輸(例如紅外線傳輸、ZigBee傳輸、超寬頻(Ultrawideband,UWB)傳輸、WiFi傳輸、射頻(Radio Frequency,RF)傳輸、DLP光訊號傳輸或藍芽(Bluetooth)傳輸)來接收視訊顯示裝置1302所發出的資訊,而控制電路1308便可基於所接收的資訊來產生所需的控制訊號S1、S2。由於熟習技藝者可輕易地得知立體眼鏡與視訊顯示裝置之間的溝通機制,故相關細節於此便不另贅述。For the example that the stereo glasses 1304 are shutter glasses, the control unit 1308 can appropriately control the left lens 1310 and the right lens 1312 to switch between an open state and a closed state. For example, the video display device 1302 can be A signal transmitter (not shown) is in communication with the stereo glasses 1304. For example, stereo glasses (eg, shutter glasses) 1304 can be transmitted by wire or wirelessly (eg, infrared transmission, ZigBee transmission, ultrawideband (UWB) transmission, WiFi. Transmission, radio frequency (RF) transmission, DLP optical transmission or Bluetooth transmission to receive information sent by the video display device 1302, and the control circuit 1308 can generate the required information based on the received information. Control signals S1, S2. Since the familiar art can easily know the communication mechanism between the stereo glasses and the video display device, the relevant details will not be further described herein.
對於第13圖所示之影像顯示系統1300而言,調整電路104所調整的至少一掃描線係對應至顯示螢幕102所顯示之有效顯示區域AA中的最後一條掃描線L_I,因此,除了原本的水平遮沒間隔資料D_HBI_L_I,調整後之水平遮沒間隔資料另包含了新增的水平遮沒間隔資料D_HBI_L_I’。當輸出電路106傳送調整後之水平遮沒間隔資料(包含有D_HBI_L_I以及D_HBI_L_I’)至顯示螢幕102的期間,對應顯示螢幕102之背光模組1306會開啟以提供顯示螢幕102所需的背光源及/或控制電路1308會開啟左眼鏡片1310與右眼鏡片1312的其中之一。換言之,經由增加對應至顯示螢幕102所顯示之有效顯示區域AA中的最後一條掃描線L_I的水平遮沒間隔資料,除了可加快有效顯示資料的傳輸以讓顯示螢幕102(例如液晶顯示螢幕)有更充裕的時間完成整個影像畫面的穩定顯示之外,還可利用傳輸新增之水平遮沒間隔資料的時間來讓使用者進行立體影像的觀看(亦即開啟立體眼鏡1304之一鏡片及/或啟動背光模組1306)。For the image display system 1300 shown in FIG. 13 , at least one scan line adjusted by the adjustment circuit 104 corresponds to the last scan line L_I in the effective display area AA displayed on the display screen 102, and therefore, in addition to the original The horizontal blanking interval data D_HBI_L_I, the adjusted horizontal blanking interval data additionally includes the new horizontal blanking interval data D_HBI_L_I'. When the output circuit 106 transmits the adjusted horizontal blanking interval data (including D_HBI_L_I and D_HBI_L_I') to the display screen 102, the backlight module 1306 corresponding to the display screen 102 is turned on to provide the backlight required for displaying the screen 102 and / or control circuit 1308 will open one of left eye lens 1310 and right eye lens 1312. In other words, by increasing the horizontal masking interval data corresponding to the last scan line L_I in the effective display area AA displayed on the display screen 102, in addition to speeding up the transmission of the effective display material to allow the display screen 102 (such as a liquid crystal display screen) to have More time is available to complete the stable display of the entire image frame, and the time for transmitting the newly added horizontal masking data can be used to allow the user to view the stereoscopic image (ie, open one of the glasses and/or one of the stereo glasses 1304). The backlight module 1306 is activated.
於第1圖與第13圖所示之實施例中,調整電路104係設置於視訊顯示裝置(例如液晶顯示器)100、1302之中,然而,本發明並不以此為限。請參閱第14圖,第14圖為本發明影像顯示系統之第三實施例的功能方塊示意圖。影像顯示系統1400包含有(但不侷限於)一視訊顯示裝置1402以及前述的調整電路104,而視訊顯示裝置1402包含有前述的顯示螢幕102以及輸出電路106,於此一實施例中,調整電路104係設置於視訊顯示裝置1402之外,舉例來說,調整電路104係設置於一電腦主機中,因此,調整電路104於完成增加水平遮沒間隔資料的處理之後,會將調整後之水平遮沒間隔資料輸入至視訊顯示裝置1402,並藉由輸出電路106傳送至顯示螢幕102。請參閱第15圖,第15圖為本發明影像顯示系統之第四實施例的功能方塊示意圖。影像顯示系統1500包含有(但不侷限於)一視訊顯示裝置1502以及前述的調整電路104與立體眼鏡1304,而視訊顯示裝置1502包含有前述的顯示螢幕102、輸出電路106以及背光模組1306,於此一實施例中,調整電路104係設置於視訊顯示裝置1502之外,舉例來說,調整電路104係設置於一電腦主機中,因此,調整電路104於完成增加水平遮沒間隔資料的處理之後,將調整後之水平遮沒間隔資料輸入至視訊顯示裝置1502,並藉由輸出電路106傳送至顯示螢幕102。由於熟習技藝者可經由先前針對其它影像顯示系統之實施例的說明而輕易地瞭解第14圖與第15圖中各個元件的功能與運作,故於此便不另贅述。In the embodiment shown in FIG. 1 and FIG. 13, the adjustment circuit 104 is disposed in the video display device (for example, the liquid crystal display) 100, 1302. However, the present invention is not limited thereto. Please refer to FIG. 14, which is a functional block diagram of a third embodiment of the image display system of the present invention. The image display system 1400 includes, but is not limited to, a video display device 1402 and the aforementioned adjustment circuit 104. The video display device 1402 includes the aforementioned display screen 102 and output circuit 106. In this embodiment, the adjustment circuit The 104 system is disposed outside the video display device 1402. For example, the adjustment circuit 104 is disposed in a computer host. Therefore, after the adjustment circuit 104 completes the process of increasing the horizontal blanking interval data, the adjusted horizontal mask is covered. The no-interval data is input to the video display device 1402 and transmitted to the display screen 102 via the output circuit 106.

Since the function and operation of the various elements in FIGS. 14 and 15 can be easily understood by those skilled in the art through the previous description of the embodiments of other image display systems, no further details are provided herein.
綜上所述,本發明影像顯示方法可簡要歸納如下:增加至少一掃描線所對應之一掃描線資料中的一水平遮沒間隔資料,以產生一調整後之水平遮沒間隔資料;以及傳送該掃描線資料中的一非水平遮沒間隔資料(例如有效影像資料或垂直遮沒間隔資料)以及該調整後之水平遮沒間隔資料至一顯示螢幕(例如液晶顯示螢幕)。換言之,藉由調整至少一掃描線所對應之一掃描線資料中的一水平遮沒間隔資料,會使得對應同一影像畫面之驅動的複數條掃描線分別具有不同長度(不同資料量)的水平遮沒間隔資料(例如:一部份的掃描線所對應之掃描線資料會具有增加的水平遮沒間隔資料,而另一部份的掃描線所對應之掃描線資料會具有原本的水平遮沒間隔資料或減少的水平遮沒間隔資料)。由於增加的水平遮沒間隔資料會使得對應至有效顯示區域之有效顯示資料的傳送加快而提早完成傳送,因此允許顯示螢幕(例如液晶顯示螢幕)有更加充裕的時間來讓影像畫面的顯示輸出達到穩定,進而大幅改善平面影像/立體影像的畫質。In summary, the image display method of the present invention can be summarized as follows: adding a horizontal blanking interval data in one scan line data corresponding to at least one scan line to generate an adjusted horizontal blanking interval data; and transmitting A non-horizontal obscuration interval data (such as valid image data or vertical obscuration interval data) and the adjusted horizontal obscuration interval data in the scan line data to a display screen (such as a liquid crystal display screen). In other words, by adjusting a horizontal blanking interval data in one of the scanning line data corresponding to the at least one scanning line, the plurality of scanning lines corresponding to the driving of the same image frame respectively have horizontal shadings of different lengths (different data amounts). No interval data (for example, the scan line data corresponding to one part of the scan line will have an increased horizontal blanking interval data, and the scan line data corresponding to the other part of the scan line will have the original horizontal blanking interval) Data or reduced levels of masking interval data). Since the increased horizontal masking interval data enables the transmission of the effective display material corresponding to the effective display area to be accelerated and the transmission is completed early, the display screen (for example, the liquid crystal display screen) is allowed to have more time for the display output of the image screen to be reached. Stable, and thus greatly improve the image quality of the flat image / stereo image.
