Problems solved by technology

However, the problem that is more likely to occur now is that due to wire or other interference during the production process, the WP will also be invalidated, and the I2C protocol communication is not normal, then there may be malfunctions that cause the TCON stored in the EEPROM to The code is rewritten, and there is no error correction mechanism today, so it is impossible to prevent this situation, which will cause abnormal display screens and frequent errors

Abstract

The present application relates to a method for protecting data in a display panel and a display device thereof. The display device includes: a display panel; a timing control unit arranged in the display panel and outputting a control signal; a judgment unit arranged in the In the display panel, a write protection input signal and the control signal are received, and when it is determined that at least one of the write protection input signal and the control signal is at a high level, a write protection output signal is output to a storage unit; and the storage unit, arranged on a drive board in the display panel, used to store the data of the timing control unit, and enter the read-only mode after receiving the write protection output signal; wherein, the The write protection output signal is at a high level; after the storage unit enters the read-only mode, the timing control unit reads the data in the storage unit.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a method for protecting data in a display panel and a display device thereof. Background technique [0002] A liquid crystal display is one of the most widely used flat panel displays, and includes two substrates having pixel electrodes, a common electrode, etc., and a liquid crystal layer interposed between the two substrates. The liquid crystal display displays images by determining the orientation of liquid crystal molecules of the liquid crystal layer and controlling the polarization of incident light by the electric field generated by the voltage applied to the electrodes. Liquid crystal displays are advantageous for displaying moving images and have high contrast, thus replacing existing cathode ray tubes, and are variously used as display devices of mobile terminals (notebook monitors, etc.), computer monitors, televisions, and the like. [0003] On the dr...
