FIELD OF THE DISCLOSURE

The present application relates to the technical field of image processing technologies, in particular to a Micro LED 8K video processing system and method therefor.

BACKGROUND

Micro-LED is a new generation of display technology (ie, an LED micro-scaling and matrixing technology), that is, an LED (Light Emitting Diode) backlight source is becoming a thin film, being miniaturized and arrayed, which makes an LED unit less than 50 microns. Same as an OLED, the Micro-LED is able to achieve that, each pixel is individually addressed and driven to emit light independently (self-luminescence). Being made of an inorganic material and in a form of self-luminescence, each sub-pixel of red, green and blue generates an own light source before being combined into a pixel. A plurality of key performances of Micro LED, including a resolution, a color gamut, a brightness, a response speed, a service life, an energy consumption, and more, are all superior to those of a mainstream LCD and an emerging OLED. Comparing with existing OLED technology, the Micro-LED has a higher brightness, a better luminous efficiency, and a lower power consumption, as well as a characteristic of self-luminescence without backlight source, a smaller size, lighter and thinner, and becomes an important development direction of an ultra-high definition television display panel.

At present, an ultra-high definition television generally adopts an LCD screen or an OLED screen with a resolution of 3840*2160 (4K), 7680*4320 (8K), as a display screen, and is in corporate with an SOC (System-on-a-Chip) chip to output a complete 4K/8K image to the display screen. Thus, a resolution of an output video signal is limited to very regular resolutions including 4K, 8K and so on. For an Micro LED ultra-high-definition television (5K/6K/7K/8K), due to a characteristic of the Micro LED of being able to be spliced arbitrarily, there is currently no SOC (system on chip) being able to be compatible with 4K/5K/6K/7K/8K screen for a complete video display at the same time. Meanwhile, since an application of an SOC in 8K is just started and a video decoding capability of 8K is under improving, there is no mature SOC that is able to be compatible with a plurality of interfaces including HDMI2.1, DP2.0 and more, while a real 8K decoding capability is not strong.

Therefore, the current technology needs to be improved and developed.

And each type of interface supports an input up to an 8K video source (video signal).

Specifically, the video processing board 200 comprises: a plurality of types of interfaces, applied to receiving the video sources with different resolutions output from the television signal source 100 (in an embodiment, the HDMI2.1 interface corresponds to a signal source of HDMI, the DP2.0 interface corresponds to a signal source of DP, and the 32 lane VBO interface corresponds to a signal source of VBO); a video segmentation module, applied to segmenting the video image into a multi-channel video signal (segmenting into 4 channels, in an embodiment); and a synchronization module, applied to encoding the multi-channel video signal (4 channels, in an embodiment) into a preset format before sending synchronously to a plurality of the 4K signal processing boards 300 (4 correspondingly, in an embodiment), while transmitting the audio decoding signal in the video source obtained after decoding to the loud-speaker 600 at a same time.

Shown as FIG. 2, if a 4K video is input and a 4K is output, then no processing is required.

Similarly, shown as FIG. 5 and FIG. 6, a video of 6K or 5K resolution can be output to adapt to the back-end of the Micro LED display screen according to this rule. When outputting to a Micro LED-4K screen, 4 channels of HDMI2.0 can output a same 4K picture, then the video processing board 200 can be used as a 4-channel 4K player.
