Hardware debugging method of TCONLESS board

Abstract

The invention provides a hardware debugging method of a TCONLESS board, which is applied to a liquid crystal screen, and the liquid crystal screen comprises the TCONLESS board and a driving board; thehardware debugging method comprises the steps that a debugging list is provided, the debugging list is provided with a debugging step, and the TCONLESS board is debugged according to the debugging step. The beneficial effects of the invention are as follows: through the debugging list, an operator can debug the TCONLESS board according to the debugging steps, so that the performance problem of the TCONLESS board is checked at a time, the problem can be quickly positioned, repeated debugging is avoided, the resource and time cost is reduced, and the development progress is accelerated.

Description

technical field [0001] The invention relates to the technical field of liquid crystal screen testing, in particular to a hardware debugging method of a TCONLESS board. Background technique [0002] With the development of technology and economy, LCD TVs including 4K_Tconless LCD screens have been introduced; among them, Tconless panel (Timing controller-less panel, less logic control screen on the panel) LCD screen is the traditional LCD TCON ( Timing controller, logic control board) module is removed, which can reduce the production cost of the display screen. However, due to the differences in the LCD screen control technology of LCD TVs of various manufacturers, the power supply and control signals required by each manufacturer's 4K_Tconless LCD screen are different, so the debugging standards of each manufacturer's 4K_Tconless LCD screen are also different, which makes the 4K_Tconless LCD screen different. Debugging and production bring great difficulties. [0003] In ...

Problems solved by technology

However, due to the differences in the LCD screen control technology of LCD TVs of various manufacturers, the power supply and control signals required by each manufacturer's 4K_Tconless LCD screen are different, so the debugging standards of each manufacturer's 4K_Tconless LCD screen are also different, which makes the 4K_Tconless LCD screen different. Debugging and production bring great difficulties

[0003] In the current existing technology, each manufacturer has different debugging schemes for the motherboard of each 4K_Tconless LCD screen, and one-to-one debugging is required. Each 4K_Tconless LCD screen cannot be used universally, that is, no unified debugging standard and process has been designed. It not only brings difficulty to the debugging and maintenance of the LCD screen, but also increases the difficulty and time of debugging
