A display may have an array of pixels such as liquid crystal display pixels. The display may include short pixel rows that span only partially across the display and full-width pixel rows that span the width of the display. The gate lines coupled to the short pixel rows may extend into the inactive area of the display. Supplemental gate line loading structures may be located in the inactive area of the display to increase loading on the gate lines that are coupled to short pixel rows. The supplemental gate line loading structures may include data lines and doped polysilicon that overlap the gate lines in the inactive area. In displays that combine display and touch functionality into a thin-film transistor layer, supplemental loading structures may be used in the inactive area to increase loading on common voltage lines that are coupled to short rows of common voltage pads.

The embodiments of the application disclose a control device for a gate driving circuit, a display panel and a display device. The control device for a gate driving circuit provided in the embodiment comprises a level shifter and a control module electrically connected with an output of the level shifter. The control module is used for controlling an output signal of the level shifter to be a low level signal when each input clock signal for the level shifter is low.

A display device includes a display panel, a driver, a detector, and an acquisition part. The driver drives the display panel based on a video signal. The detector obtains a first detection value by detecting reflective light from reflective media, which occurs when ambient light is irradiated to reflective media, while obtaining a second detection value by detecting reflective light from reflective media, which occurs when the display panel irradiates its display light to reflective media. The driver corrects a drive value for the display panel such that the second detection value approaches the first detection value or such that the chromaticity represented by the second detection value approaches the chromaticity represented by the first detection value, and therefore the acquisition part acquires information concerning the color temperature of ambient light based on the corrected drive value.

A liquid crystal display driving method provided includes the following steps: acquiring a current gray level value of a current frame image; determining a gray level of the current gray level value; if the current gray level value is the high gray level, then determining whether to perform an overvoltage driving according to a first gray level difference threshold value; if the current gray level value is the low gray level, then determining whether to perform the overvoltage driving according to a second gray level difference threshold value. The present invention can precisely determine whether to perform the overvoltage driving on the pixel electrode.
