Abstract

The invention relates to the technical field of liquid crystal display, in particular to a mobile phone, a liquid crystal display screen and a normal display method of the liquid crystal display screen under a low temperature condition. The method comprises the steps of providing a liquid crystal module which comprises a liquid crystal driving voltage adjusting unit used for adjusting the driving voltage of a liquid crystal; presetting a critical temperature, defining temperatures higher than the critical temperature to be in a first temperature range, and defining temperatures lower than the critical temperature to be in a second temperature range; detecting a current first temperature of the liquid crystal display screen; acquiring the current first temperature; when the current first temperature belongs to the first temperature range, enabling the liquid crystal driving voltage adjusting unit to drive the liquid crystal display screen in a constant voltage driving manner; when the current first temperature belongs to the second temperature range, enabling the liquid crystal driving voltage adjusting unit to drive the liquid crystal display screen in a variable voltage driving manner. Under the low temperature condition, corresponding driving voltage is selected, so that the liquid crystal display screen can normally display.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a mobile phone, a liquid crystal display and a normal display method thereof under low temperature conditions. Background technique [0002] At present, the vast majority of smartphones on the market use LCD screens and use a fixed voltage to drive the LCD screen. When the external temperature of the LCD screen is between -10°C and -15°C in winter, the LCD screen of the mobile phone will have screen smear, blurry display or even cannot display normally. The higher the value, the subtle defects of the screen will be magnified, and the above problems will greatly affect the user experience. Contents of the invention [0003] In view of the deficiencies in the prior art, the object of the present invention is to provide a mobile phone, a liquid crystal display and a method for displaying it normally under low temperature conditions. The LCD screen will have abnorm...
