Abstract

The invention provides an OLED display panel, a manufacturing method, a drive method and a display device to reduce the thickness of the OLED display panel and to improve the brightness and the flexible bending degree of the OLED display panel. The OLED display panel comprises a light-emitting unit, a quarter-wave plate and a wire grid polarizer, wherein the quarter-wave plate and the wire grid polarizer are sequentially arranged on the light-emitting unit; the light-emitting unit comprises a drive backboard, a light-emitting layer and a cathode layer; the cathode layer comprises a plurality of cathode sub-electrodes which extend along a first direction and are insulated with one another; the cathode sub-electrodes transmit cathode signals during a display stage of the display panel and transmit touch drive signals during a touch stage of the display panel; the wire grid polarizer comprises a plurality of metal wires which extend along a second direction; at least one part of metal wires form a plurality of touch induction electrodes; the touch induction electrodes transmit touch induction signals during the touch stage of the display panel; and the second direction is intersected with the first direction.

Description

technical field [0001] The present application relates to the display field, in particular to an OLED display panel, a manufacturing method, a driving method and a display device. Background technique [0002] Current display types mainly include liquid crystal display (Liquid Crystal Display, LCD), organic light-emitting diode display (Organic Light-Emitting Diode, OLED), plasma display (Plasma Display Panel, PDP) and electronic ink display. Among them, the Active-matrix organic light emitting diode (AMOLED) in the OLED display is a new type of display device, which has high chromaticity, high contrast, wide viewing angle, high brightness, self-illumination, and fast response. , can realize flexible display and other characteristics, has been recognized as the next generation of flat panel display technology. [0003] like figure 1 Shown is a schematic structural diagram of an AMOLED display panel in the prior art, including a driving backplane 11, a light-emitting layer ...
