Embodiment Construction

[0037] Please refer to figure 1 , figure 1 It is a schematic diagram of a data compression system 10 according to an embodiment of the present invention. The data compression system 10 can be used in a liquid crystal display. The data compression system 10 includes a main device unit 100 and a driving circuit 120 . The main device unit 100 is used to output an image data Img_D in a data format frmt1 or a data format frmt2 according to an operation mode of the LCD. The driving circuit 120 can preferably be realized by a driving chip (Drive IC). The driving circuit 120 includes an image data unit 121 , a compression unit 122 , switching units 123 and 126 , a storage unit 124 , a decompression unit 125 , a display unit 127 , a bypass path L1 and a complete data path L2. The switching units 123 and 126 are used to switch the bypass path L1 or the full data path L2. The compression unit 122 is configured to receive the image data Img_D according to the operation mode and execu...

Abstract

The invention discloses a data compression system for a liquid crystal display and a power-saving method thereof. The data compression system comprises a main device unit and a driving circuit, wherein the main device unit is used for outputting an image data by a first data format or a second data format according to an operation mode of the liquid crystal display; the driving circuit comprises a bypass path, a compression unit, a storage unit and a decompression unit; the bypass path is used for transmitting the image data according to the operation mode; the compression unit is used for executing a compression program on the image data according to the operation mode to generate compression data; the decompression unit is used for executing a decompression program on the compression data according to the operation mode to restore the image data.

Description

technical field [0001] The invention relates to a data compression system for liquid crystal displays, in particular to a data compression system capable of selecting a data transmission path according to an operation mode and a related power saving method. Background technique [0002] Liquid Crystal Display (LCD) has the advantages of thin and light appearance, power saving and low radiation, so it has been widely used in computer screens, mobile phones, personal digital assistants (PDAs), flat-screen TVs, and other communication / entertainment equipment and other electronic products. The working principle of the liquid crystal display is to change the alignment state of the liquid crystal molecules in the liquid crystal layer by changing the voltage difference between the two ends of the liquid crystal layer, thereby changing the light transmittance of the liquid crystal layer, and then cooperate with the light source provided by the backlight module to display images. ...
