Description

technical field [0001] The invention relates to the field of display technology, in particular to an organic electroluminescent diode display panel and a driving method thereof. Background technique [0002] Organic light-emitting diode (Organic Light-Emitting Diode, OLED) displays are more and more widely used in various display devices because of their thinness, lightness, power saving and other characteristics. An OLED display generally includes an array of organic light emitting diodes (that is, a pixel array), and a pixel circuit that provides driving current to each organic light emitting diode in the array. [0003] Such as figure 1 Shown is a schematic structural diagram of a pixel circuit of an existing OLED display. The pixel circuit includes a first transistor T1, a second transistor T2, a second transistor T3, a storage capacitor Cst and an organic light emitting diode D. The gate of the first transistor T1 is connected to the first scan line S1, the first pol...

Full afterglow will cause dizziness and greatly affect the sensory experience

In a VR display device, within a frame time, pixels need to emit light for about 20% of the time, and be in a dark state for the rest of the time, and all pixels in the entire panel are simultaneously in a light-emitting state or a dark state. It is difficult for the pixel circuit and driving method provided by the prior art to realize such a display mode
