Abstract

The invention discloses a display screen and a control method thereof as well as a display device, belonging to the technical field of display. The display screen comprises a display panel and a control circuit, wherein a thin-film transistor in an array substrate in the display panel comprises a source, a drain, an active layer and n gates, wherein the control circuit is connected with a target gate and an auxiliary gate in the n gates separately; the control circuit is used for inputting first off-state voltage into the target gate in an off-state time period and inputting second off-state voltage into the auxiliary gate in the off-state time period, so that a target PN junction is formed in the active layer under the action of the voltage on the n gates; and the forward turn-on direction of the target PN junction is opposite to the flow direction of current in the area, except for the area of the target PN junction, in the active layer. According to the display screen and the control method thereof as well as the display device, the problem that a TFT cannot be normally used is solved, the effect that the TFT can be normally used is achieved and the control method is applied to the display screen.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display screen, a control method thereof, and a display device. Background technique [0002] The display screen includes a display panel and an array substrate line drive (English: Gate driver On Array; GOA for short) circuit, wherein the display panel includes an array substrate and a color filter substrate formed in a box, and a gate driver on array between the array substrate and the color filter substrate. of LCD. The array substrate includes a base substrate and a plurality of thin film transistors (English: Thin Film Transistor; TFT for short) formed on the base substrate and arranged in an array. [0003] In related technologies, a thin film transistor includes a gate, a source, a drain and an active layer, wherein the gate, the electrode and the drain are all made of metal, and the material of the active layer is semiconducting carbon nanotubes. When the voltage app...
