Problems solved by technology

That is, in the AMOLED display panel of the prior art, the touch screen 15 is separately arranged above the light-emitting unit (including the driving backplane 11, the light-emitting layer 12, and the cathode layer 13), and then the touch screen 15 is arranged on the top of the touch screen 15. A circular polarizer that reduces external light reflection and enhances contrast, but the AMOLED display panel with this structure has the problems of thicker overall structure and poor flexibility and curvature

Abstract

The present application provides an OLED display panel, a manufacturing method, a driving method and a display device, so as to reduce the thickness of the OLED display panel and improve the brightness and flexibility of the OLED display panel. The OLED display panel includes: a light-emitting unit, and a quarter-wave plate and a wire grid polarizer sequentially arranged on the light-emitting unit, wherein the light-emitting unit includes a driving backplane, a light-emitting layer, and a cathode layer. The cathode layer includes a plurality of cathode sub-electrodes extending along the first direction and insulated from each other, the cathode sub-electrodes transmit cathode signals during the display phase of the display panel, and transmit touch driving signals during the touch phase of the display panel; the wire grid The polarizer includes a plurality of metal wires extending along the second direction, at least some of the metal wires form a plurality of touch sensing electrodes, and the touch sensing electrodes transmit touch control during the touch control phase of the display panel. A signal is sensed, the second direction intersects 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] Such as 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 lay...
