Embodiment 1-1

[0210] In a feasible embodiment, the image quality processing feedback result received by the first chip is image quality processing; the first video signal received by the first chip is a video signal in RGB format.

[0211] For the conversion process of specific video signals, please refer to Figure 10a :

[0212] When the video signal received by the first chip is in RGB format, using the display device shown in the embodiment of the present application, the first chip receives the image quality processing feedback result fed back by the second chip to perform image quality processing, and the corresponding first conversion format is YUV signal format. The first chip determines that the received first video signal received by the first chip is a video signal in RGB format. The first chip directly converts the received video signal into a video signal in YUV format, and then sends the video signal in YUV format to the second chip. The second chip receives video signals i...

Embodiment 1-2

[0216] In a feasible embodiment, the image quality processing feedback result received by the first chip is image quality processing; meanwhile, the first video signal received by the first chip is a video signal in YUV format:

[0217] For the conversion process of specific video signals, please refer to Figure 10b :

[0218] When the video signal received by the first chip is in YUV format, using the display device shown in the embodiment of the present application, the first chip receives the image quality processing feedback result fed back by the second chip to perform image quality processing, and correspondingly, the first conversion The format is YUV signal format. The first chip determines that the received first video signal received by the first chip is a video signal in YUV format, and the first chip directly sends the received video signal in YUV format to the second chip. The second chip receives video signals in YUV format, performs corresponding image qualit...

Embodiment 2-1

[0224] In a feasible embodiment, the image quality processing feedback result received by the first chip is no image quality processing, and the first video signal received by the first chip is a video signal in RGB format. For the conversion process of specific video signals, please refer to Figure 11a :

[0225] When the video signal received by the first chip is in RGB format, using the display device shown in the embodiment of the present application, the first chip receives the feedback result of image quality processing fed back by the second chip that image quality processing is not performed, and correspondingly, the first The conversion format is RGB signal format. The first chip determines that the received first video signal received by the first chip is a video signal in RGB format, and the first chip directly sends the received video signal in RGB format to the second chip. The second chip directly sends the video signal received in RGB format to the display sc...

Abstract

An embodiment of the invention discloses a color space switching method and a display device. The display device comprises a first chip and a second chip, wherein the first chip receives a first videosignal and an image quality processing feedback result sent by the second chip, the first chip determines a first conversion format according to the image quality processing feedback result, and thesecond chip converts the first conversion format into a second conversion format according to the second conversion format. The first chip converts the first video signal into a signal in a first conversion format to generate a first output video signal; the second chip processes the first output video signal to generate a second output video signal in an RGB format; the second chip sends the second output video signal to a display screen. According to the display device, the scheme of dynamically adjusting the output format of the first chip is adopted, the number of times of space conversionof the video signal in the video signal transmission process is small, then the precision loss of the video signal in the transmission process is reduced, and the scheme is particularly suitable fora social television.

Description

[0001] This application claims the priority of the Chinese patent application with application number 201910498720.8 filed with the State Intellectual Property Office on June 10, 2019. The entire contents of which are incorporated by reference in this application. technical field [0002] The embodiments of the present application relate to display technology. More specifically, it relates to a color space switching method and a display device. Background technique [0003] At present, because the display device can provide users with playback images such as audio, video, and pictures, it has attracted widespread attention from users. With the development of big data and artificial intelligence, users have increasing demands on the functions of display devices. For example, the user wants to watch high-definition cable TV through the display device, and sometimes the user wants to watch Internet TV through the display device. [0004] The display device can meet the above...
