Control methods for timer control register of display panel and display panel

Abstract

The invention discloses control methods for a timer control register of a display panel and the display panel. A method comprises the steps that a pulse modulation module generates a write protectionlevel and outputs the write protection level into a write protection pin of a storage chip; a sensing circuit detects a practical level value of the write protection pin; the practical level value iscompared with the write protection level, and a comparison result is sent to the timer control register; and the timer control register controls whether to read timer control register initialization configuration codes stored in the storage chip or not according to the comparison result. The sensing circuit for the write protection level is added to the pulse modulation module, and whether to switch on or switch off an inter-integrated circuit bus is decided through utilization of the sensed practical write protection level, so the condition that images are abnormal due to the fact that the timer control register codes are read wrongly is avoided.

Description

technical field [0001] The invention relates to the field of display devices, in particular to a control method for a timing control chip of a display panel and a display panel. Background technique [0002] With the development and progress of science and technology, liquid crystal displays have become the mainstream products of displays due to their thin body, power saving and low radiation, and have been widely used. Most of the liquid crystal displays currently on the market are backlight liquid crystal displays, which include a liquid crystal panel and a backlight module. The working principle of the liquid crystal panel is to place liquid crystal molecules between two parallel glass substrates, and apply a driving voltage on the two glass substrates to control the rotation direction of the liquid crystal molecules, so as to refract the light from the backlight module to produce a picture. [0003] Among them, Thin Film Transistor-Liquid Crystal Display (TFT-LCD) has g...

Problems solved by technology

[0004] Generally, there will be internal resistance loss between the circuits of the LCD panel, which will lead to voltage instability, thereby affecting the output of the signal, resulting in abnormal pictures, and reducing the efficiency of experiments and production.
