Problems solved by technology

[0006] Adding a liquid crystal accelerator between the display control device and the panel module can certainly improve the response speed of the liquid crystal display, but in addition to having a circuit on the liquid crystal accelerator that determines the pixel data that accelerates the twisting of the liquid crystal, it also needs to have an interface that matches the display control device and the panel module Signal receiver and interface signal transmitter, therefore, this liquid crystal accelerator greatly increases the cost of liquid crystal display, thereby reducing the profit of liquid crystal display manufacturers

Embodiment Construction

[0031] In the following, the technical content, characteristics and functions of the present invention will be described in more detail by using the embodiments in conjunction with the description of the drawings, so as to enable a deeper understanding.

[0032] Please refer to image 3 , a block diagram of the first embodiment of the liquid crystal display control device of the present invention. As shown in the figure, the liquid crystal display control device 300 of this embodiment has a scaling unit 302 , a liquid crystal acceleration driving unit 304 , and an interface signal transmission unit 306 . The scaling unit 302 receives an input source image, scales the source image into image data with a proper resolution, and then transmits it to the liquid crystal acceleration driving unit 304 . The liquid crystal accelerated driving unit 304 is coupled to a memory 380, and stores the pixel data constituting a picture frame (imageframe) in the image data in the memory 380, wh...

Abstract

The present invention proposes a liquid crystal display control device, which is an integrated integrated circuit device, which includes: a scaling unit, which is used to reduce or enlarge the image frame of an input image signal to output an output image signal; a liquid crystal an acceleration drive unit, coupled to the scaling unit, used to adjust the output image signal to accelerate the display response speed of the liquid crystal panel; and an interface signal transmission unit, coupled to the liquid crystal acceleration drive unit, to convert the adjusted output image signal into a standard Interface signal output.

Description

technical field [0001] The present invention relates to a display control device, in particular to a liquid crystal display control device with a liquid crystal acceleration driving unit, which is integrated into a single integrated circuit chip. Background technique [0002] Generally speaking, a TV or computer monitor can only display a specific resolution, and the source image data is provided by an image controller (such as: graphics card, video decoder, digital camera, etc.), and the resolution of the source image data is also As a given, therefore, an adjustment must be made to the source image data to make it scaled (scaling) into image data with an appropriate resolution, so that the display screen can correctly display the output image data. [0003] Please refer to figure 1 , a block diagram of a display control device, the source image data is first transmitted to the scaling unit 102 of the display control device 100, and the scaling unit 102 scales the source i...
