Abstract

The invention discloses a method and a system for preventing unexpected modification of LCD setting. The method comprises the following steps: monitoring a write operation to a plurality of LCD registers, and acquiring a first write rule carried in the write operation; judging whether the first write rule is the same as a preset write rule or not; and if the first write rule is judged to be not the same as the preset write rule, filtering the write operation. The preset write rule is configured through the write operation generated by mobile terminal, and the write operation in which the write rule is not carried is defaulted to be an unexpected operation which is filtered. Thus, the write operation executed by the LCD registers can be generated by the system, the unexpectedly generated write operation to the LCD registers is avoided, and then the problem of LCD display abnormality caused by unexpected modification of the LCD setting is solved.

Description

technical field [0001] The invention relates to the technical field of intelligent terminals, in particular to a method and system for preventing accidental modification of LCD settings. Background technique [0002] With the development of smart terminal technology, smart terminals with touch screens are increasingly favored by users. At present, the touch screen of the smart terminal is mainly an LCD display, and the display setting of the LCD display is usually implemented by writing into the LCD register. However, the existing LCD display screen and the user operation surface are only covered with a very thin protective film, so that the LCD display screen is easily affected by static electricity in the external environment, resulting in accidental modification of the LCD settings and affecting the LCD display. Display function. For example, when the static electricity on the user's hand touches the display screen of the terminal device in dry winter, the static electr...
