As shown in FIG. 2, the width and height of the original image frame F_IN are W0 and H0, respectively, in other words, the original image frame F_IN can be regarded as having H0 scanning lines, and each scanning line of the original image frame F_IN can be regarded as having W0. Pixel, in addition, the effective display data of the original image frame F_IN is AA_0 (which corresponds to display data of H01*W01 pixels, for example, W01=1920 and H01=1080), and the vertical blanking interval area data of the original image frame F_IN is VBI_0. (corresponding to the display data of H02*W01 pixels), the horizontal blanking interval area data of the original image frame F_IN includes HBI _AA _0 (which corresponds to the display data of the valid display data AA_0 and has H01*W02 pixels) and HBI _VBI _0 (which corresponds to the vertical blanking interval area data VBI_0 and has display data of H02*W02 pixels).

In the first implementation manner, the processing unit 122 in the processing circuit 104 directly uses the data of the original image frame F_IN as the data of the first image frame F1. As shown in FIG. 3, the effective display of the first image frame F1. The data AA_1 will be equal to AA_0, the vertical blanking interval area data VBI_1 of the first image frame F1 will be equal to VBI_0, and the horizontal blanking interval area data of the first image frame F1 contains HBI _AA _1 equal to HBI _AA _0 and HBI _VBI _0, respectively. With HBI _VBI _1, please note that in the first implementation manner, the first scan line data D ₁ includes the valid display data AA_1 and the horizontal blanking interval area data HBI _AA _1, and the second scan line data D described above. ₂ includes a vertical blanking interval data and horizontal blanking interval VBI_1 region information HBI _VBI _1, therefore, the first scan line data D ₁ will AA_1 effective display data containing data for all of the effective display screen F_IN AA_0 in the original image.

In addition, for the second image frame F2 immediately after the first image frame F1, the amount of data is smaller than the amount of data of the first image frame F1. As shown in FIG. 4, the width of the second image frame F2 is The heights are respectively W0 and H2 (H2<H0). Therefore, the second image frame F2 can be regarded as having H2 scanning lines, and each scanning line of the second image frame F2 can be regarded as having W0 pixels, and in addition, the second image The effective display data of the screen F2 is AA_2 (which corresponds to the display data of H21*W01 pixels), and the vertical blanking interval area data of the second image screen F2 is VBI_2 (which corresponds to the display data of H22*W01 pixels), and the second The horizontal blanking interval area data of the image screen F2 includes HBI _AA _2 (which corresponds to the display data of the effective display data AA_2 and having H21*W02 pixels) and HBI _VBI _2 (which corresponds to the vertical blanking interval area data VBI_2) In the present embodiment, the data amount of the effective display data AA_2 is different from the data amount of the effective display data AA_1, for example, the scan lines of the effective display data AA_2. Different number The number of scan lines of the data AA_1 is effectively displayed (that is, (H21≠H01); further, in the embodiment, the data amount of the vertical blanking interval area data VBI_2 is not necessarily equal to the data amount of the vertical blanking interval area data VBI_1. For example, the number of scanning lines of the vertical blanking interval area data VBI_2 is not necessarily equal to the number of scanning lines of the vertical blanking interval area data VBI_1 (that is, (H22≠H02), in one embodiment, the vertical blanking interval The number of scan lines of the area data VBI_2 can be smaller than the number of scan lines of the vertical mask interval area data VBI_1, so that the amount of data effectively displaying the data AA_2 can be increased to further improve the image quality of the planar image/stereoscopic image. Note that in the first implementation manner, the third scan line data D ₃ includes the valid display material AA_2 and the horizontal blanking interval area data HBI _AA _2, and the fourth scan line data D ₄ includes the vertical blanking interval. information VBI_2 the horizontal blanking interval data area HBI _VBI _2, therefore, the first image frame F1 and the second image may have a respective actual level F2 display blanking interval.

As can be seen from the figure, the second image frame F2 is only a partial image frame rather than a complete image frame compared to the first image frame F1. In other words, the corresponding output image of the effective display data AA_2 of the second image frame F2 is not The valid display area in the display screen 102 is filled. In the first implementation manner of the processing circuit 104, when the valid display data AA_0 of the original image frame F_IN is used to drive the effective display area of the display screen 102 to display the image image having the same color, the second image frame F2 is valid. The display data AA_2 may include an all-white display material (for example, each pixel value in the valid display data AA_2 is "255") or a full black screen display data (for example, each pixel value in the valid display data AA_2 is "0" For example, when the display screen 102 uses a TN type liquid crystal display panel, the effective display data AA_2 of the second image frame F2 is set to be displayed by the processing unit 112 in the processing circuit 104 as an all white screen display data. On the one hand, when the display screen 102 adopts a VA type liquid crystal display panel, the effective display data AA_2 of the second image frame F2 is set to be displayed by the processing unit 112 in the processing circuit 104 as a full black screen display data, and thus, based on The display characteristics of the TN type liquid crystal display panel and the VA type liquid crystal display panel itself can appropriately set the effective display data AA_2 of the second image frame F2, which can make the display The display screen 102 displays data according to the effective image frame F1 of the first AA_1 same color picture can be maintained for a long period of time, thus allowing the user to see more clearly the planar image or a stereoscopic image. In addition, in the first implementation manner of the processing circuit 104, when the valid display data AA_0 of the original image frame F_IN is used to drive the effective display area of the display screen 102 to display image images having different colors (for example, image images of different screen contents) When the processing unit 112 of the processing circuit 104 sets the valid display data AA_2 of the second image frame F2 to the display data related to the effective display data AA_0 of the original image frame F_IN, and sets the effective display of the second image frame F2. The operation of the data AA_2 can be one of a plurality of processing methods described below.

The first processing method is: the processing unit 112 of the processing circuit 104 can directly repeat a part of the effective display data AA_0 of the original image frame F_IN as the effective display data AA_2 of the second image frame F2, for example, effectively displaying the data. AA_2 may be the content of the set of the plurality of scan lines in the upper half of the effective display data AA_0, the content of the set of the plurality of scan lines located in the lower half, the contents of the set of the plurality of scan lines located in the central portion, and the whole The content of the set of even scan lines in the picture, the content of the set of odd scan lines in the entire picture, or the content of any set of scan lines in the entire picture.

The second processing method is: the processing unit 112 of the processing circuit 104 performs interpolation processing (for example, averaging processing) through the effective display data of the valid display data AA_0 of the original image frame F_IN and the next original image frame F_IN', and A part of the content of the interpolation processing is selected as the effective display material AA_2 of the second image frame F2.

The third processing method is: the processing unit 112 of the processing circuit 104 performs superimposition processing on the effective display data of the original display image A__0 and the next original image frame F_IN' of the original image frame F_IN, and selects from the superimposed processing result. A part of the content is used as the effective display data AA_2 of the second image frame F2. For example, the effective display data of the original display image A__0 and the next original image frame F_IN' can be appropriately mixed. Then, the superimposition processing result is generated through the addition or subtraction processing, that is, the processing unit 112 of the processing circuit 104 determines the second image frame F2 by the dithering concept of the superimposition processing. Effective display of data AA_2.

The fourth processing method is: the processing unit 112 of the processing circuit 104 performs specific image processing on the effective display data AA_0 of the original image frame F_IN (for example, adjustment of contrast, adjustment of saturation, adjustment of gamma value, adjustment of sharpness, and / or brightness adjustment), and select a part of the image processing results as the effective display data AA_2 of the second image frame F2.

The fifth processing method is that the processing unit 112 of the processing circuit 104 sets the valid display data AA_2 of the second image frame F2 only according to the scan line content of the effective display data AA_0 of the original image frame F_IN that is not all black or not all white. For example, the processing unit 112 of the processing circuit 104 sets the valid display data AA_2 of the second image frame F2 only according to the scan line content of the effective display data AA_0 of the original image frame F_IN that does not belong to the black margin, for example, The processing unit 112 of the processing circuit 104 first detects whether there is a scan line content located at the top of the screen and the black side below the screen in the valid display data AA_0 of the original image frame F_IN, and if the effective display data AA_0 of the original image frame F_IN is detected. If the content of the scan line belonging to the black border is included, the valid display material AA_2 of the second image frame F2 will not contain the scan line content with the black border.

The sixth processing method is that the processing unit 112 of the processing circuit 104 determines which pixels of the display need to be specifically optimized based on the component characteristics of the display screen 102 (eg, the reaction time of each liquid crystal cell), for example, processing by the processing circuit 104. The unit 112 can refer to the overdrive comparison table or the additionally established comparison table to learn the liquid crystal unit having a longer reaction time in the display screen (for example, the liquid crystal display screen) 102, and set the effective effect of the second image frame F2 accordingly. The data AA_2 is displayed to enable these liquid crystal cells to be rotated by appropriate driving to achieve the desired state.

Please note that the above description is for illustrative purposes only, and is not a limitation of the present invention, that is, any technique for adding at least one partial image display material between display data of two original full image frames ( Or any technique for increasing the image update rate by overlaying the image may be employed by the processing unit 112 of the processing circuit 104 to generate the desired valid display data AA_2.

As shown in the foregoing, the second image frame F2 is transmitted to the display screen 102 immediately after the first image frame F1, and the data amount of the second image frame F2 is smaller than the data amount of the first image frame F1. Therefore, the second image frame is F2 will update a part of the content of the first image frame F1 (ie, the original image frame F_IN). For example, the valid display data AA_0 of the original image frame F1 includes a first valid display data AA_01 and a second effective display data. AA_02, and the content displayed by the second valid display data AA_02 is replaced/updated by the display content of the valid display data AA_2. Therefore, the effective display data AA_2 can be used to correct or improve the content of the second valid display data AA_02 originally displayed. In general, the scan lines driven by the second valid display data AA_02 (which corresponds to the first image frame F1) and the effective display data AA_2 (which corresponds to the second image frame F2) are sequentially displayed as better images. Output the result.

Please note that the second image frame is F2 and not a complete image frame. Therefore, the size of the second image frame can be appropriately set to the size of the F2 (for example, the effective display of the data AA_2) can be appropriately matched with the bandwidth limitation of the display screen 102 and the application requirements. Data volume). For example, the total number of scan lines included in the valid display data AA_2 may be determined based on the refresh rate, the power environment in which the video display device is located, and/or the light source blinking frequency/ambient brightness of the video display device. In an embodiment, when the screen update rate is high, the total number of scan lines included in the valid display data AA_2 is small, and vice versa; when the AC frequency of the power environment where the video display device is located is high, the data is effectively displayed. The total number of scan lines included in AA_2 will be less, and vice versa; when the frequency of the light source of the video display device is high, the total number of scan lines included in the valid display data AA_2 will be less, and vice versa; When the brightness of the environment in which the video display device is located is high, the total number of scan lines included in the valid display data AA_2 is small, and vice versa.

Please refer to FIG. 2, FIG. 5 and FIG. 6 together. FIG. 5 is a schematic diagram of the first image frame F1 outputted by the processing circuit 104 shown in FIG. 1 in the second embodiment, and FIG. The figure is a schematic diagram of the second image frame F2 outputted by the processing circuit 104 shown in FIG. 1 in the second embodiment. In the second implementation manner, the processing unit 122 in the processing circuit 104 is the set of the first valid display data AA_01 of the original image frame F_IN and the effective display data AA_2 of the second image frame F2 in the first implementation manner described above. The effective display data AA_1' of the first image frame F1 is set as the effective display data AA_1' of the first image frame F1, and the effective display data AA_2' of the subsequent second image frame F2 is set by the second effective display data AA_02 of the original image frame F_IN in the first implementation manner. . Please note that in the second implementation manner, the first scan line data D ₁ includes the valid display data AA_1′ and the horizontal blanking interval area data HBI _{AA —} 1, and the second scan line data D ₂ described above may include VBI_1 vertical blanking interval data and horizontal blanking interval data area _HBI VBI_ 1, therefore, the first scan line data D of the effective display data AA_1 _'1 will contain the original image in a part of the screen F_IN effective display data, in addition, the above-described The third scan line data D ₃ will contain the valid display data AA_2' and the horizontal blanking interval area data HBI _{AA_} 2, and the fourth scan line data D ₄ described above will include the vertical blanking interval data VBI_2 and the horizontal blanking interval area. The data HBI _VBI _2, therefore, the valid display data AA_2' of the third scan line data D ₃ will contain the valid display data of another part of the original image frame F_IN.

Comparing Figures 3 and 5 and comparing Figures 4 and 6, it can be easily seen that in the second implementation mode, the processing circuit 104 displays a portion of the original image frame F_IN (i.e., the first effective). The display data AA_01) is first transmitted to the display screen 102 by the valid display data AA_1' of the first image frame F1, and then the other part of the original image frame F_IN is displayed (ie, the second valid display data AA_02) is followed by The valid display data AA_2' of the second image frame F2 is transmitted to the display screen 102. In addition, the effective display data AA_2 generated by one of the plurality of processing modes described above is firstly displayed by the first image frame F1. The data AA_1' is transmitted to the display screen 102. Please note that the scan lines (first implementation mode) driven by the second valid display data AA_02 and the valid display data AA_2 are sequentially and the data AA_2 is sequentially displayed. The scan line (the second implementation mode) driven by the second effective display data AA_02 will produce substantially the same image output result, so that the image quality can be improved.

In the first and second implementation manners of the processing circuit 104, a part of the image image (that is, the second image frame F2) is added after a complete image frame (that is, the first image frame F1). A part of the image frame (ie, the second image frame F2) may also be added before a complete image frame (ie, the first image frame F1). Please refer to FIG. 7. FIG. 7 is a functional block diagram of a second embodiment of the image display system of the present invention. In this embodiment, the image display system is implemented by a video display device 700. As shown in the figure, the video display device 700 includes a display screen 102 and a processing circuit 704 coupled to the display screen 102. In this embodiment, the processing circuit 704 includes a processing unit 712 and a temporary storage unit 114, wherein the processing unit 712 can be an image scaling processing circuit, and the temporary storage unit 114 can be a frame buffer. Similarly, the processing unit 712 can process the received original image frame F_IN through a built-in microprocessor, and output the first image according to the output. The scan line data of the screen F1' and the second image frame F2' is sent to the temporary storage unit 114. Further, the processing circuit 712 transmits one of the first scan line data D ₁ ' and the first image corresponding to the first image frame F1'. The second scan line data D ₂ ′ is displayed to the display screen 102, and the third scan line data D ₃ ′ corresponding to the second image frame F2 ′ immediately after the first image frame F1 ′ and a fourth scan line data D are transmitted. ₄ ' to display screen 102. However, in this embodiment, the first image frame F1' is a partial image frame, and the second image frame F2' is a complete image frame. For example, the first image frame F1' is a fourth image/ The second video frame F2 shown in FIG. 6 (that is, D ₁ '=D ₃ and D ₂ '=D ₄ ), and the second video frame F2 ′ are the first shown in FIG. 3 / FIG. 5 . Image picture F1 (ie, D ₃ '=D ₁ and D ₄ '=D ₂ ). Since the skilled artisan can easily understand the operation of the video display device 700 shown in FIG. 7 based on the contents of the previous manual, it will not be further described herein.

As described above, by appropriately setting the contents of the newly added second video frame F2/first video frame F1', the image quality can be improved. In addition, the transmission of other data can be accelerated by the newly added second image frame F2. Since the effective display data of the first image frame F1 located before the second image frame F2 can be transferred to the display screen 102 by the processing circuit 104, Therefore, the display screen 102 (for example, the liquid crystal display screen) has more time to complete the stable display of the entire image frame; likewise, the newly added first image frame F1' can also accelerate the transmission of other data, because it is located at the first The effective display data of the second image frame F2 after the image frame F1' can be transferred to the display screen 102 by the processing circuit 104, thereby enabling the display screen 102 (for example, the liquid crystal display screen) to have more time to complete the stable display of the entire image frame. . For the operation of the additional information to speed up the transmission of other data, refer to other Taiwan patent applications of the same applicant (for example, Taiwan Patent Application No. 100104886 and Taiwan Patent Application No. 100101348), and therefore no further details are provided herein.

The driving mechanism disclosed by the present invention can be applied to stereoscopic image display in addition to flat image display. Please refer to FIG. 8.

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 804 are available for the user to wear to view the stereoscopic image presented by the video display device 802 through the display screen 102.

For the example that the stereo glasses 804 are shutter glasses, the control unit 808 can appropriately control the left lens 810 and the right lens 812 to switch between an open state and a closed state. For example, the video display device 802 can be A signal transmitter (not shown) is in communication with the stereo glasses 804. For example, stereo glasses (eg, shutter glasses) 804 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 802, and the control circuit 808 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 800 shown in FIG. 8, the processing circuit 104 sequentially transmits the first image frame F1 (complete image frame) and the second image frame F2 (partial image frame), and thus, the processing circuit 104 During the transmission of the second, third, and fourth scan line data D ₂ -D ₄ , the backlight module 806 corresponding to the display screen 102 is turned on to provide the backlight and/or control circuit 808 required to display the screen 102 to turn left. One of the ophthalmic lens 810 and the right ophthalmic lens 812.
