A method for displaying a video signal without loss of frames and a display device

Abstract

The present application discloses a video signal frame-free display method and display device. The SOC module receives the video source signal, and according to the resolution and refresh frequency of the video source signal, and according to the upper limit input amount of the first FRC module and the second The upper limit input of the second FRC module determines the SOC output signal, and inputs the SOC output signal to the first FRC module and the second FRC module respectively; the first FRC module processes the SOC output signal to obtain the first FRC output signal; the second FRC The module processes the SOC output signal to obtain the second FRC output signal; the first FRC module inputs the left picture frame to the display screen according to the resolution and refresh rate of the first FRC output signal; the second FRC module inputs the right picture frame according to The resolution and refresh rate of the second FRC output signal are input to the display screen. The application can realize the frame-free display of high-resolution and high-refresh-frequency signals.

Description

technical field [0001] The present application relates to the technical field of display device signal processing, and in particular to a method for displaying a video signal without frame loss and a display device. Background technique [0002] At present, this field is committed to high-resolution, high-refresh-frequency picture display, such as realizing 8K×4K@120Hz on the display device. The more information can be displayed in the display area, the 120Hz refresh rate TV adopts the intelligent frequency multiplication drive technology on the basis of the existing 60Hz, which doubles the speed of screen scanning and the flipping of liquid crystal molecules, which can effectively eliminate afterimages , Solve the smearing problem of moving pictures on ordinary LCD screens, reduce visual fatigue, and make the picture quality healthier. [0003] After the video source signal output by the signal device enters the SOC (System On Chip, System on Chip) module for processing, t...

Problems solved by technology

[0004] Taking the signal device outputting 8K×4K@60Hz video source signal and realizing 8K×4K@120Hz high resolution and high refresh rate screen display as an example, due to the limitation of hardware performance of the current FRC module, the maximum can only support The input of 16lane data volume results in the limitation of the resolution and refresh rate of the signal output from the SOC module to the FRC module, generally fixed at 8K×4K@30Hz or 4K×4K@60Hz

If the SOC module fixedly outputs 8K×4K@30Hz signals to the FRC module, there will be a problem of signal frame loss; if the SOC module fixedly outputs 4K×4K@60Hz signals to the FRC, although there will be no frame loss, it cannot Realize 8K×4K resolution display
