The horizontal blanking interval data of HBI_12 will sequentially include a synchronization signal SYNC and a trailing edge signal BP, and the horizontal blanking interval data belonging to another horizontal blanking interval region HBI_22 will include a leading edge signal FP.

As described above, for each scan line L_0~L_N, the scan line data includes horizontal blanking interval data (ie, synchronous signal SYNC, trailing edge signal BP, and leading edge signal FP) and non-horizontal blanking interval data. (that is, the effective display data or the vertical blanking interval data), in order to facilitate the description of the technical features of the present invention, the output screen of the display screen 102 can be further represented by FIG. 3, wherein the output screen of the display screen 102 can be divided into The effective display area AA and the blank area (including the horizontal blanking interval area HBI _AA , HBI _VBI and the vertical blanking interval area VBI), wherein the horizontal blanking interval area HBI _AA corresponds to the effective display area AA in the horizontal direction, and It can be regarded as a set of the synchronization signal SYNC, the trailing edge signal BP and the leading edge signal FP of the scan lines L_0~L_I.

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.

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)

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.

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)

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.

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.

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.

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.

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.

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.

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.

Please note that the driving mechanism disclosed in the present invention can be applied to stereoscopic image display in addition to flat image display. 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.

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.

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.

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.

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.

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 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. Please refer to FIG. 15, which is a functional block diagram of a fourth embodiment of the image display system of the present invention. The image display system 1500 includes, but is not limited to, a video display device 1502 and the aforementioned adjustment circuit 104 and stereo glasses 1304. The video display device 1502 includes the foregoing display screen 102, output circuit 106, and backlight module 1306. In this embodiment, the adjustment circuit 104 is disposed outside the video display device 1502. For example, the adjustment circuit 104 is disposed in a computer host. Therefore, the adjustment circuit 104 performs processing to increase the horizontal blanking interval data. Thereafter, the adjusted horizontal blanking interval data is input to the video display device 1502 and transmitted to the display screen 102 by the output circuit 106.
