Problems solved by technology

[0003] In order to meet the normal reading of the above data volume, the display driver chip needs to be equipped with multiple parallel mini-LVDS interfaces, which not only increases the complexity of the display driver chip structure, but also increases the complexity of the board-level circuit design (because it needs to set Multiple mini-LVDS interfaces), and because the display driver chip needs to read too much data, the refresh rate of the display is too slow, and the user experience is poor

Embodiment 1

[0039] figure 1 A schematic structural diagram of the display driving chip provided by Embodiment 1 of the present invention is shown. see figure 1 , the display driver chip provided by Embodiment 1 of the present invention includes sequentially connected: an input interface 100, a first conversion module 200, a decompression module 300, a second conversion module 400, and an output interface 500;

[0040] The input interface 100 is used to receive the first display data and send the first display data to the first conversion module; the first display data is compressed data to be displayed; the data to be displayed can be The image data can also be video data;

[0041] Here, the input interface 100 of the display driver chip no longer receives the R, G, B, W signals after RGBW conversion like the input interface of the traditional display driver chip, but receives the compressed display data, which makes the amount of received data greatly reduce.

[0042] The first conve...

Embodiment 2

[0067] Based on the same inventive concept, Embodiment 2 of the present invention provides a display substrate, which includes the display driving chip as described in the above embodiments.

[0068] The display substrate in this embodiment may be various types of display substrates such as a liquid crystal display substrate, an organic light emitting diode display substrate, and the like. Since the display substrate includes the above-mentioned display driving chip, it can solve the same technical problem and achieve the same technical effect.

Embodiment 3

[0070] Based on the same inventive concept, Embodiment 3 of the present invention provides a display device, which includes the display substrate as described in the above embodiments.

[0071] The display device in this embodiment may be various types of display devices such as liquid crystal displays, organic light emitting diode displays, and the like. Since the display device includes the above-mentioned display substrate, it can solve the same technical problem and achieve the same technical effect.

Abstract

The invention provides a display driving chip, a display substrate, a display device and a display driving method. The display driving chip comprises an input interface, a first conversion module, a decompression module and a second conversion module, wherein the input interface is used for receiving first display data and sending the first display data to the first conversion module; the first conversion module is used for carrying out serial-parallel conversion on the first display data to obtain parallel data and sending the parallel data to the decompression module; the decompression module is used for decompressing the obtained parallel data to obtain second display data and sending the second display data to the second conversion module; and the second conversion module is used for carrying out RGBW conversion on the second display data to obtain third display data and sending the third display data to an output interface to be output. The display driving chip provided by the invention has the advantages that the decompression module and the second conversion module are arranged in the chip, so that the chip can receive compressed display data, and decompression and RGBW conversion processes are completed inside the chip, so that data input volume is reduced, data input efficiency of the chip is improved, and quantity of the input interfaces of the chip is reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display driving chip, a display substrate, a display device and a display driving method. Background technique [0002] The traditional display driver chip reads the R, G, B, W signals after image decompression and RGBW conversion through the mini-LVDS interface. [0003] In order to meet the normal reading of the above data volume, the display driver chip needs to be equipped with multiple parallel mini-LVDS interfaces, which not only increases the complexity of the display driver chip structure, but also increases the complexity of the board-level circuit design (because it needs to set Multiple mini-LVDS interfaces), and because the display driver chip needs to read too much data, the refresh rate of the display screen is too slow, and the user experience is poor. Contents of the invention [0004] Aiming at the defects in the prior art, the present invention provides a ...
