An organic light-emitting display panel and display device

Abstract

The invention provides an organic light emitting display panel and a display device. The organic light emitting display panel comprises a plurality of data lines extending along the row direction, a plurality of scanning lines extending along the column direction, a plurality of pixel units defined by the data lines and the scanning lines, a plurality of first wires extending along the column direction, at least one signal control unit, at least one signal processing unit and at least switch control unit, wherein each of the first wires is connected to at least one column of the pixel units; the switch control unit comprises a control end, an input end and an output end; the control end is connected with the signal control unit, the input end is connected with the signal processing unit, and the output end is connected with at least one of the first wires; and when the switch control unit is turned on, the signal processing unit outputs high voltage signals to all of the pixel units, and all of the pixel units on the organic light emitting display panel display an image.

Description

technical field [0001] The present invention relates to the display field, in particular to an organic light-emitting display panel and a display device. Background technique [0002] Virtual reality (Virtual Reality, referred to as VR) creates a virtual environment for users in an imitative way. Through visual, auditory, tactile and other sensory behaviors, users can feel immersed in the virtual environment and interact with the virtual environment to cause Real-time changes in the virtual environment. Due to the principle of VR display and human physiological functions, it will cause smearing, afterglow and other phenomena. Therefore, it is recognized in the industry that the refresh rate should be increased and the afterglow should be reduced by emitting light from the panel pixels together. The former is easy to do, just adjust the line frequency. The latter requires the OLED devices in the entire panel to emit light at the same time. If the gate lines are turned on a...

Problems solved by technology

[0003] Although adjusting PVEE can solve the problem of IC current limitation, since the current OLED panel cathode is evaporated on the entire surface, the parasitic capacitance C of the light-emitting diode oled And the influence of other parasitic capacitances (such as the parasitic capacitance between traces) will affect the gate potential of the drive tube, and due to the existence of parasitic capacitance, after the IC pulls PVEE down, the cathode will experience a large delay time to reach the ideal low potential, thus affecting the display of the normal screen
