2. Description of the Prior Art
In the prior art, a display chip can process image data from the left side and the right side. Due to requirements for some particular panel design, however, the output image data from a transmission port and an image processing unit might not be symmetric. Some parts of the image data from left side and the right side are overlapped. Or when the display device is performing particular image process, for example, Zigzag application, color process, edge enhancement or multi-port transmission, the image processing chip at the front end has to send the overlapped image data to the display chip.
It is therefore an objective of the present invention to provide a non-overlap data transmission method for a liquid crystal display.
The present disclosure provides a non-overlap data transmission method for a liquid crystal display (LCD). The non-overlap data transmission method includes obtaining an entire fame image data; dividing the entire frame image data into a plurality of image data segments and individually sending the image data segments to a plurality of display processing units at the same time, wherein each of the image data segments is sent to one of the display processing units and image data of each image data segment does not overlap with image data of the other image data segments; and mutually sending image data of the image data segments through the display processing units.
The present disclosure further provides a transmission circuit for a liquid crystal device (LCD). The transmission circuit includes a plurality of transmission ports and a plurality of display processing units. The plurality of transmission ports are used for obtaining an obtaining an entire fame image data and dividing the entire frame image data into a plurality of image data segments and individually sending the image data segments to a plurality of display processing units at the same time, wherein each of the image data segments is sent to one of the display processing units and image data of each image data segment does not overlap with image data of the other image data segments. The plurality of display processing units are used for receiving the image data segments and mutually sending image data of the image data segments through, wherein each of the display processing units individually receives one of the image data segments.
These and other objectives of the present invention will no doubt become obvious to those of ordinary skill in the art after reading the following detailed description of the preferred embodiment that is illustrated in the various figures and drawings.
Please refer to FIG. 1 , which is a schematic diagram of an exemplary transmission circuit 10. The transmission circuit 10 can be used in a liquid crystal display (LCD) device for performing non-overlap data transmission. The transmission circuit 10 includes multiple transmission ports 100 and multiple display processing units 120. The transmission ports 100 are used for obtaining an entire frame image data IMG from a front end circuit (e.g. image processing chip) and dividing the entire frame image data into multiple image data segments img_1, img_2, . . . , img_n, and individually sending the image data segments img_1, img_2, . . . img_n to the display processing units 120. Each of the image data segments img_1, img_2, . . . , img_n is sent to one of the display processing units 120, and the image data of each image segment does not overlap with the image data of the other image segments. In other words, the image segments do not share the same image data with each other and each image segment corresponds to one of the display processing units 120. The display processing units 120, preferably, can be implemented by display chips. After receiving the image data segments, the display processing units 120 mutually send the image data of the image data segments img_1, img_2, . . . , img_n to each other, in order to support the particular image process (e.g. Zigzag application, color process, edge enhancement or multi-port transmission) when the overlapped image data is not supported.
Take two transmission ports as an example, please refer to FIG. 2 . FIG. 2 is a schematic diagram of another exemplary transmission circuit 20. The transmission circuit 20 can implement the transmission circuit 10 in FIG. 1 . The transmission circuit 20 includes a first transmission port 200, a second transmission port 220, a first display chip 240 and a second display chip 260. After the entire frame image data IMG is received, the first transmission port 200 and the second transmission port 220 individually send left side image data img_l and right side image data img_r of the entire frame image data IMG to the first display chip 240 and the second display chip 260. The structure of the particular LCD device may cause that the left side image data segment img_l and the right side image data segment are not symmetric (i.e. the left side image data segment img_l and the right side image data segment have different amounts of pixels). After the first display chip 240 and the second display chip 260 receive the left side image data segment img_l and the right side image data segment img_r, respectively, the transmission circuit 20 allows the first display chip 240 and the second display chip 260 to mutually send the left side image data segment img_l and the right side image data segment img_r to each other, compensating for the missing image data due to the asymmetric structure. Thus, it is not necessary to send the same boundary data between the left image and the right image, repeatedly. Besides, the transmission circuit 20 can perform particular image process (e.g. Zigzag application, color process, edge enhancement or multi-port transmission) by mutually sending the left side image data segment img_l and the right side image data segment img_r via the first display chip 240 and the second display chip 260 when the overlapped image data is supported.

As shown in FIG. 3 , the first display chip 240 sends the boundary image data of the left side image data segment img_l, which is adjacent to the right side image data segment img_r, to the first display chip 260 since Zigzag application causes the image data shifting. In FIG. 4 , the upper part illustrates the left side image data segment img_l and the right side image data segment img_r in the normal mode, and the lower part illustrates the left side image data segment img_l and the right side image data segment img_r when the Zigzag application is performed.
