[0018] The following describes embodiments of the present application in more detail with reference to the accompanying drawings. Although the accompanying drawings illustrate embodiments of the present application, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to make the present application more thorough and complete, and to fully convey the scope of the present application to those skilled in the art.

[0019] It should be understood that although the terms "first", "second", "third", etc. may be used in this application to describe various information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this application, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0020] Unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," and the like should be interpreted broadly. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0021] Display screens are currently widely used across various fields. In related technologies, 2K and 4K displays have lower resolutions than 8K displays. However, many 2K and 4K films and TVs cannot be played on 8K displays. Therefore, a TCON board is urgently needed that can convert 2K and 4K technology to 8K.

[0022] To address the above issues, an embodiment of the present application provides a TCON board that is compatible with 2K and 4K input to 8K output, which can convert 2K input and 4K input into 8K output.

[0023] The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0024] See also Figure 1 A TCON board compatible with 2K and 4K input to 8K output includes: a first input module 100, a second input module 200 and a third input module 300, the first input module 100 includes a first input terminal and a conversion chip, the input terminal is electrically connected to the conversion chip; the second input module 200 includes a second input terminal and an output pin, the second input terminal is electrically connected to the conversion chip, and the output pin is set on the second input terminal; the third input module 300 includes a receiving terminal and a common pin, the common pin is set on the receiving terminal, and the common pin is electrically connected to the output pin.

[0025] It should be noted that the first input terminal is a 2K input terminal, the second input terminal is a 4K input terminal, and the receiving terminal is an 8K input terminal and a 4K signal source at the second input terminal. Specifically, the 2K signal source is an LVDS input signal, which is connected to a conversion chip that can convert the 2KLVDS input signal into a 4K V-By-One signal. Through the conversion process, the 2K LVDS signal is converted into a 4K signal that can be recognized by the TCON IC.

[0026] See also Figures 1 to 4 In one embodiment, the first input module 100 further includes an LVDS signal pin, which is provided on the first input terminal and electrically connected to the conversion chip. Pins 6-26 are 2K LVDS signal inputs.

[0027] See also Figures 1 to 4 In one embodiment, the second input module 200 includes a plurality of output pins, each of which is disposed at the second input terminal. Specifically, the third input module 300 includes a plurality of shared pins, each of which is disposed at the receiving terminal. Specifically, the number of shared pins is the same as the number of output pins.

[0028] It should be noted that since the Tcon IC can only receive 32 pairs of data lines, the first 8 pairs are designed to be shared, as indicated by the outline. When using 4K input, RX0 to RX7 are enabled; when using 8K input, RX0 to RX31 are enabled. The 4K input interface and the 8K input interface are designed to overlap, sharing some pads. In actual use, simply select the appropriate interface based on the source video. By debugging the corresponding software, the system can automatically identify different input signals and switch Tcon modes. This design enables 4K to 8K conversion and is compatible with 4K and 8K signal inputs.

[0029] See also Figure 5 The second aspect of the present application provides a method for converting 2K and 4K input to 8K output, comprising:

[0030] Step S101: The conversion chip receives a 2K signal source, converts the 2K signal source, and outputs a 4K signal source.

[0031] Step S102: Send the 4K signal source to the receiving end to output the 8K signal source.

[0032] It should be noted that the conversion chip receives a 2K signal source, converts the 2K signal source into a 4K signal source output, then sends the 4K signal source to the receiving end, and finally outputs an 8K signal source.

[0033] In one embodiment, converting a 2K signal source includes: collecting pixels of the 2K signal source and outputting position information of the pixels at a 4K resolution;

[0034] The surrounding pixels of the pixel point are collected, and the first algorithm is used to calculate the real-time pixel value to output the 4K signal source.

[0035] It should be noted that the first algorithm may be a method such as bilinear interpolation or cubic interpolation to calculate a new real-time pixel value.

[0036] In one embodiment, converting the 2K signal source includes: performing a calculation on the 2K signal source using a second algorithm in a deep learning model to output a pre-processed 4K image;

[0037] The pre-processed 4K image is optimized and output as a 4K signal source.

[0038] It should be noted that the second algorithm can capture image details and textures using convolutional layers and activation functions, etc. Noise reduction and sharpening are then performed on the output pre-processed 4K image, and finally a 4K signal source is output.

[0039] The scheme of the present application has been described in detail above with reference to the accompanying drawings. In the above embodiments, the descriptions of each embodiment have their own emphasis. For parts that are not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments. Those skilled in the art should also be aware that the actions and modules involved in the description are not necessarily required for this application. In addition, it is understood that the steps in the method of the embodiment of the present application can be adjusted in sequence, merged and deleted according to actual needs, and the modules in the device of the embodiment of the present application can be merged, divided and deleted according to actual needs.

[0040] The embodiments of the present application have been described above. The above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is selected to best explain the principles of the embodiments, their practical applications, or improvements to the technology in the market, or to enable other persons skilled in the art to understand the embodiments disclosed herein.
