T-CON drive board applied to display

Abstract

The invention discloses a T-CON drive board applied to a display. The T-CON drive board comprises an input terminal, a main chip control module, a storage module, a power supply module, an adjusting module, a level conversion module and an output module. The input terminal is electrically connected with the main chip control module, the storage module, the power supply module and the adjusting module, the input end of the level conversion module is electrically connected with the main chip control module, the output end of the level conversion module is electrically connected with the output module, and the main chip control module is further electrically connected with the storage module and the power supply module. According to the invention, the optical compensation storage unit is arranged, DEMURA calibration is realized; therefore, the phenomena of color cast and uneven brightness of the large-size panel can be eliminated; the T-CON drive board has the advantages that the structure is simple and convenient and flexible to calibrate, CSF2211-A0N is adopted as a TCON IC, the 2K resolution ratio and the 165 Hz refresh rate can be achieved, the Source board and the TCON board canbe combined and optimized, the production efficiency is improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of optoelectronic panels, in particular to a T-CON driving panel applied to a display. Background technique [0002] At present, people's demand for commercial display is increasing, such as large-size screen display for design and drawing, and high-resolution and high-refresh rate display for some commercial applications. To this end, we have developed a T-CON driver board for 32-inch commercial displays, which can be used by domestic display brand end customers. The resolution and image refresh rate can support up to 2560x1440, 75Hz or 1920x1080, 165Hz. This size monitor is suitable for gaming, business display, animation and graphic design. [0003] In the existing design, due to the limitations of the crystallization process, the LTPSTFT fabricated on a large-area glass substrate often has non-uniformity in electrical parameters such as threshold voltage and mobility. Sex will be converted into the current diffe...

Problems solved by technology

[0003] In the existing design, due to the limitations of the crystallization process, the LTPSTFT fabricated on a large-area glass substrate often has non-uniformity in electrical parameters such as threshold voltage and mobility. Sex will be converted into the current difference and brightness difference of the display device, and finally the color difference can be recognized by the human eye, that is, the mura phenomenon

If this defect is not eliminated, the display will cause color cast troubles in commercial display, animation and graphic design

In addition, for general images, an image refresh rate of 60Hz can be regarded as smooth, but 60Hz is a bit powerless in the face of games that require quick response.
