Abstract
The embodiment of the invention discloses an OLED display panel, a manufacturing method thereof, and a display device. The OLED display panel includes: a pixel array layer and a light-emitting device layer, and a lens array layer located between the pixel array layer and the light-emitting device layer; the light-emitting device layer includes a plurality of light-emitting units, and the pixel array layer is provided with a plurality of openings area; the lens array layer includes a lens arranged between the light-emitting unit and the pixel array layer; the lens is used to converge the light emitted by the light-emitting unit and reach the lens, and emit the converged light to the opening area of the pixel array layer . The embodiments of the present invention solve the problems of low luminous efficiency and poor brightness of the existing bottom emission OLED display panel.
Description
technical field [0001] The present application relates to but not limited to the field of display technology, especially to an OLED display panel, a manufacturing method thereof, and a display device. Background technique [0002] The organic electroluminance display (Organic Electroluminance Display, referred to as: OLED) panel does not need a separate light source due to its self-luminous feature, and can be made lighter and thinner, and has been widely used in the field of display technology. [0003] Since the thin film transistor (Thin Film Transistor, referred to as: TFT) area (ie TFT area) of the current OLED display panel cannot transmit light, for the bottom emission OLED display panel, it is necessary to set a special opening area in the pixel array layer. The pixel array layer is formed by the opening area and the TFT area. Therefore, the opening ratio of the bottom-emission OLED display panel usually can only reach about 20%, so that the luminous efficiency and b...
