The first dithering module is configured to receive the first bit display data, and convert the first bit display data into the second bit display data; the overdrive module is configured to receive the second bit display data, and the second bit is displayed The bit display data is driven to operate; the selector has a first selection mode and a second selection mode, and the selector receives the second bit display data from the overdrive module; when the selector is in the first selection mode, the selector switches Connected to the first output terminal, the second bit displays the data; when the selector is in the second selection mode, the selector switches to the second dither module, and the second dither module receives the second bit display data.第二 causing the second bit display data to be converted into the third bit display data after being processed by the wobbling technology; and the second output terminal is connected to the second flutter module, and the third bit is displayed to display the data.

Another object of the present invention is to provide a display data processing method for a liquid crystal display. The display data processing method comprises the steps of: receiving a first bit display data, and causing the first bit display data to be converted after being processed by a wobbling technique; Displaying data for the second bit; driving the second bit display data; when in the first selection mode, the second bit displaying data is output by the first output; and when in the second selection mode, The second bit display data is converted into the third bit display data after being processed by the wobbling technique to be output by the second output terminal.

The advantage of the application of the present invention is that the display data processing device and the display data processing method can enable different bit data to share the same overdrive module, thereby saving hardware cost and easily achieving the above purpose.

Referring to Fig. 1, there is shown a block diagram of a data processing apparatus 1 according to a first embodiment of the present invention. The display data processing device 1 includes a first fluttering module 100, an overdrive module 102, a selector 104, a first output end 106, a second fluttering module 108, and a second output end 110. The first dithering module 100 is configured to receive the first bit display material 101. The first dithering module 100 in turn converts the first bit display material 101 into a second bit display material 103. For example, the first bit display data 101 can be a 10-bit display data, and the second bit display data 103 can be an 8-bit display data. After being processed by the dithering technology of the first dithering module 100, on the corresponding 8-bit liquid crystal display, after receiving the 8-bit display data, a visual effect equivalent to 10 bits can be presented on the display. In various embodiments, the first dithering module 100 can be implemented by different dithering algorithms, such as average dithering, random dithering, or patterning dithering. ), etc., to achieve the effect of the wobbling process. The overdrive module 102 is configured to receive the second bit display data 103 and perform a drive operation on the second bit display data 103. The purpose of the overdrive operation is to speed up the reaction speed of the liquid crystal display by the effect of overvoltage. Therefore, the overdrive module 102 includes an overdrive lookup table to perform overdrive operations based on the overdrive lookup table.

The selector 104 receives the second bit display material 103 that has passed the drive operation from the overdrive module 102. The selector 104 has a first selection mode and a second selection mode. When the selector 104 is in the first selection mode, the switch is connected to the first output 106 and the overdrive module 102. When the selector 104 is in the second selection mode, the switch is connected to the second dither module 108 and the overdrive module 102. Therefore, when the selector 104 is in the first selection mode, the selector 104 will directly output the second bit display material 103 to the first output 106 after receiving the second bit display material 103. The first output 106 is substantially more connected to a second bit liquid crystal display 112 to display a second bit display (not shown) according to the second bit display data 112. That is, if the second bit display data 103 is an 8-bit display material, the second bit liquid crystal display 112 is an 8-bit liquid crystal display to display an 8-bit display according to the 8-bit display data. Picture. When the selector 104 is in the second selection mode, the selector 104 will send the second bit display material 103 to the second dithering module 108. After receiving the second bit display material 103, the second dithering module 108 performs another dithering technique processing to convert the second bit display material 103 into the third bit display material 107. In one embodiment, the second bit display data 103 can be an 8-bit display data, and the third bit display data 107 can be a 6-bit display data. The second output terminal 110 is connected to the second dithering module 108. After the third bit display material 107 is generated, the third bit display material 107 is output. The second output terminal 110 is substantially more connected to a third bit liquid crystal display 114 to display a third bit display screen (not shown) according to the third bit liquid crystal display 114. That is, if the third bit display data 107 is 6-bit display data, the third bit liquid crystal display 114 is a 6-bit liquid crystal display to display a 6-bit display according to the 6-bit display data. Picture. After being processed by the fluttering technology of the first dithering module 107, on the corresponding 6-bit liquid crystal display, after receiving the 6-bit display data, a visual effect equivalent to 10 bits can be presented on the display.
