Problems solved by technology
[0003] The current ultra-high-definition TV mainly receives 2K×1K signals, and after decoding and image quality processing, it drives the ultra-high-definition screen through amplification processing to realize ultra-high-definition display; for 4K×2K signals, it needs to be converted into 2K×1K, high cost, complex operation, low stability and reliability, and defects such as image distortion and blurring
That is, the problem existing in the prior art is: because the TV chip of the existing UHD TV is designed for the full HD signal, when the film source is a 4K×2K signal, its UHD screen cannot realize ultra-high resolution for the UHD signal. HD display

Embodiment Construction
[0066] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0067] The invention discloses a control method for ultra-high-definition display, referring to figure 1 , in this implementation manner, the control method for ultra-high-definition display includes the following steps:
[0068] Step S01, decomposing the received 4K×2K signal into 2K×1K transitional signals.
[0069] By decomposing the received 4K×2K signal into 2K×1K transitional signal, it can meet the signal format requirements of current TV decoding and image processing.
[0070] Step S02 , decoding the 2K×1K transition signal to obtain a 2K×1K screen display signal.
[0071] Step S03, converting the 2K×1K on-screen display signal into a 4K×2K target signal to provide to an ultra-high-definition screen for ultra-high-definition display.
[0072] By converting the 2K×1K screen display signal into a 4K×2K target...

The invention provides an ultra-high-definition display control method and an ultra-high-definition display control device as well as an ultra-high-definition television, wherein the ultra-high-definition display control method comprises the following steps that received 4K*2K signals are resolved into 2K*1K transition signals; the 2K*1K transition signals are subjected to decoding processing, and 2K*1K screen display signals are obtained; and the 2K*1K screen display signals are converted into 4K*2K target signals, the 4K*2K target signals are provided for an ultra-high-definition screen, and the ultra-high-definition display is realized. For a film source of 4K*2K signals, the film source is resolved into the 2K*1K transition signals so that the traditional television chip can conveniently carry out the decoding processing, the 2K*1K screen display signals are obtained, the 2K*1K screen display signals subjected to the decoding processing are synthesized into the 4K*2K target signals, and the goal that the ultra-high-definition screen realizes the ultra-high-definition display on ultra-high-definition signals is reached.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to an ultra-high-definition display control method and device, and an ultra-high-definition television. Background technique [0002] Ultra-high-definition TV (UHDTV) is a TV with a pixel count of 3840×2160 (4K×2K) or 7680×4320 (8K×4K). The number of pixels has increased by 4 times or 16 times, so its image performance is very clear and delicate. The ultra-high-definition television standard formulated by ITU-R includes 4K×2K standard and 8K×4K standard, and 4K×2K UHDTV is easier to implement and popular than 8K×4K UHDTV. [0003] The current ultra-high-definition TV mainly receives 2K×1K signals, and after decoding and image quality processing, it drives the ultra-high-definition screen through amplification processing to realize ultra-high-definition display; for 4K×2K signals, it needs to be converted into 2K×1K, high cost, complicated operation, low stability and reli...
