Embodiment 1

[0032] This embodiment provides a method for setting the driving mode of LCD in electronic equipment. LCD can be divided into TN (TwistedNematic, twisted nematic) type, VA (VerticalAlignment, vertical alignment) type, IPS (In-PlaneSwitching, plane switching) Type, LTPS (LowTemperaturePoly-silicon, low-temperature polysilicon) type. The setting method of this embodiment is applicable to any electronic equipment terminal with LCD structure, such as mobile phone, tablet computer, PDA (Personal Digital Assistant, personal digital assistant), POS (Point of Sales, sales terminal), vehicle-mounted computer and other terminal equipment. The LCD includes a liquid crystal array such as figure 1 shown, including:

[0033] Step 101, judging whether the initial driving mode of the LCD is the first driving mode, and setting the driving mode of the LCD to the first driving mode if the judgment result is no;

[0034] The first driving mode is used to drive the liquid crystals in the liquid ...

Embodiment 2

[0037] Such as figure 2 As shown, the difference between this embodiment and embodiment 1 is that: after step 101, it also includes:

[0038] Step 102, reducing the voltage of the data line electrically connected to the LCD.

[0039] Reducing the voltage of the data line is to reduce the voltage of the data line, wherein the driving mode of the LCD includes the first driving mode and the second driving mode, and the power consumption generated by driving the LCD in the second driving mode is higher than The first driving mode drives the power consumption generated by the LCD. The first driving mode includes a row inversion driving mode and a column inversion driving mode, namely rowinversion and columninversion. The second driving mode includes dot inversion driving mode, frame inversion driving mode and delta inversion driving mode, namely dotinversion, frameinversion and deltainversion.

[0040] The liquid crystal molecules in the liquid crystal array have a characterist...

Embodiment 3

[0043] This embodiment provides an electronic device 100, such as image 3 As shown, it includes LCD1, the LCD includes a liquid crystal array 11, and the electronic device includes a first judgment module 2;

[0044] The first judging module 2 is used to judge whether the initial driving mode of the LCD is the first driving mode, and set the driving mode of the LCD as the first driving mode when the judgment result is no, and the first A driving mode is used to drive the liquid crystals in the liquid crystal array to flip in units of a row of liquid crystals in the liquid crystal array.

[0045] The electronic device in this embodiment can be a terminal such as a mobile phone, a tablet computer, etc., which can use the setting method in Embodiment 1 to work, and this embodiment can achieve the same technical effect as Embodiment 1.

Abstract

The invention discloses a setting method for a driving mode of an LCD in electronic equipment and the electronic equipment. The LCD comprises a liquid crystal array; the setting method comprises the steps that whether an initial driving mode of the LCD is a first driving mode or not is judged, and if not, the driving mode of the LCD is set as the first driving mode; the first driving mode is used for driving turnover of liquid crystals in the liquid crystal array by taking a row of the liquid crystals in the liquid crystal array as a unit. According to the setting method for the driving mode of the LCD in the electronic equipment and the electronic equipment, power dissipation of the LCD is decreased in the mode of driving turnover of the liquid crystals in the liquid crystal array by taking a row of the liquid crystals in the liquid crystal array as the unit to change the supply voltage of the LCD, the pixel count of a display picture of mobile equipment cannot be changed, therefore, the power dissipation of the LCD can be decreased on the condition that the picture quality of the display picture of the mobile equipment is not influenced, and the running time of the mobile equipment is further prolonged.

Description

technical field [0001] The invention relates to a method for setting a driving mode of an LCD (Liquid Crystal Display, liquid crystal display) in an electronic device and the electronic device. Background technique [0002] At present, in order to maintain the communication function of the device and prolong the communication time, most manufacturers of mobile devices have set power-saving modes for users to choose. power consumption. The commonly used methods to reduce the power consumption of the LCD include reducing the display frequency of the LCD, reducing the resolution of the screen, reducing the resolution of the output screen of the mobile device, and then zooming in to the required resolution through an algorithm. However, these methods for reducing the power consumption of the LCD will reduce the display quality of the screen of the mobile device. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the ...
