Display device, control method thereof and electronic equipment

Abstract

The embodiment of the invention provides a display device, a control method thereof and electronic equipment; the display device comprises a display panel and a control circuit, and the control circuit is arranged in a control circuit setting area of the display panel; the display panel comprises a substrate, a scanning drive circuit located on one side of the substrate, at least one virtual pixeland a plurality of sub-pixels; each sub-pixel comprises at least one first transistor, and a second transistor is arranged in the virtual pixel; the virtual pixel is capable of generating a virtual pixel according to a first reference signal and a second reference signal provided by a control circuit, and outputting a threshold detection signal related to the threshold voltage of the second transistor, so that the control circuit can output a corresponding control signal according to the threshold detection signal, and control the scanning signal provided by the scanning drive circuit to control the first transistor in the sub-pixel to be switched on or switched off. According to the embodiment of the invention, the first transistor in the sub-pixel can be accurately controlled to be switched on or off, so that the display effect is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display device, a control method thereof, and an electronic device. Background technique [0002] Organic Light-Emitting Diode (OLED) display panels have broad application prospects due to their advantages such as self-illumination, high contrast ratio, thin thickness, fast response speed, and being applicable to flexible panels. [0003] The OLED element of the OLED display panel is a current-driven element, and a corresponding pixel driving circuit needs to be provided to provide a driving current for the OLED element so that the OLED element can emit light. A pixel driving circuit of an OLED display panel generally includes a storage capacitor, a driving transistor and other transistors electrically connected to the driving transistor. A scan driving circuit is usually provided in an active matrix OLED display, and the scan driving circuit can ou...
