Abstract: A bezel of a display includes source lines with a same length, gate in panel (GIP) lines, and at least two customized integrated circuit (IC) chips arranged along a straight line in a lateral direction. Each of the customized IC chips is coupled to at least one of the source lines or the GIP lines. Circuit layouts on the customized IC chips are, together, equivalent to a circuit layout on a standard IC chip. A sum of widths of the customized IC chips in the lateral direction is greater than a width of the standard IC chip.

Abstract: A display method and display device are provided. The method includes: detecting whether a displayed content in a display screen changes; in response to detecting that the displayed content does not change, controlling the display screen to update alternately display data respectively corresponding to odd pixels and even pixels in each row of display unit. The number of updated pixels of the display screen each time may be reduced, while the original refresh frequency is maintained, so the problem that the splash screen phenomena is caused in the display screen by reducing the refresh frequency of the display screen may be solved, thus achieving effects of avoiding the splash screen phenomena of the display screen and of reducing the power consumption of the display screen while maintaining the original refresh frequency of the display screen.

Abstract: An LCD panel, a terminal device and a photo-sensing control method are provided. The LCD panel includes: a backlight source, an array substrate disposed on the backlight source; a photosensitive device array disposed on the array substrate; and a control circuit coupled to the photosensitive device array. By disposing the photosensitive device array on the array substrate of the LCD panel, a front panel of the terminal device is not required to be divided into multiple regions. Therefore, the camera function can be integrated into the LCD panel, and only the LCD panel is needed in the front panel of the terminal device which has both the display function and the camera function. The integration and appearance of the front panel of the terminal device is thus improved.

Abstract: Methods and an apparatus for setting brightness of a display screen of an electronic device based on ambient light brightness. The method includes acquiring by a light sensor on the electronic device a measured brightness of ambient light having an actual ambient brightness at where the electronic device is located; detecting whether the light sensor faces away from a light source in the environment; when it is detected that the light sensor does not face away from the light source, determining a reference backlight brightness level according to a backlight brightness level-setting function comprising a correspondence between actual ambient brightness levels and backlight brightness levels, by using the measured brightness as actual ambient brightness; and setting an actual backlight brightness of the backlighted display screen to the reference backlight brightness level; and when it is detected that the light sensor faces away from the light source, setting the actual backlight brightness of the backlighted display screen at a level different from the reference backlight brightness level.

Abstract: A display method, device and a computer-readable medium are provided. The method includes: detecting whether there is any change in a displayed content for the display; in response to detecting that the displayed content for the display does not change, controlling the display to alternately update display data corresponding to a first portion and a second portion of display units in each row when the display unit comprises m rows of pixels; and in response to detecting that the displayed content for the display does not change, controlling the display to alternately update display data corresponding to a third portion and a fourth portion of display units in each column when the display unit comprises n columns of pixels. Herein m and n are positive integers. Thus, screen flicker caused by reduction of refresh frequency of a display while the display content does not change can be avoided.
