Organic light-emitting display device and manufacture method thereof

Abstract

The invention discloses an organic light-emitting display device comprising an array substrate and a color film substrate facing each other. The array substrate comprises a thin-film transistor drive layer arranged on a base plate, a pixel defining layer, an organic light-emitting layer, and a grid; the pixel defining layer is disposed on the organic light-emitting layer and defines pixel light-emitting areas; the organic light-emitting layer is disposed in the pixel light-emitting area on the thin-film transistor drive layer; the grid is disposed outside the pixel light-emitting areas and surrounds every pixel light-emitting area. The organic light-emitting display device has the advantages that display frame color mixing occurs less rarely and utilization rate of white light is increased.

Description

technical field [0001] The invention relates to flat panel display technology, in particular to an organic light-emitting display device and a manufacturing method thereof. Background technique [0002] In recent years, white organic light emitting diodes (White Organic Light Emitting Diode, WOLED) can be made into paper-thin light source sheets, and can be used as backlight sources for liquid crystal displays and full-color organic light-emitting display devices. Diodes are becoming an important display technology. [0003] Generally, full-color organic light-emitting display devices follow the principle of full-color liquid crystal display (Liquid Crystal Display, LCD), use white light organic light-emitting diodes to emit light, and then use color filters to filter out three primary colors. Mature color filter technology to achieve full-color display. [0004] like figure 1 As shown, in the prior art full-color organic light-emitting display device 1 , the organic ligh...

Problems solved by technology

[0005] to combine figure 2 As shown, when the viewing angle is tilted to 70°, the brightness of the full-color organic light-emitting display device 1 is about 60% of the maximum brightness, that is, at a larger viewing angle, the full-color organic light-emitting display device 1 still has relatively high brightness, so The display screen will produce serious color mixing phenomenon

In addition, because the white light L is emitted in a divergent form, the light emitted by the G color filter film only accounts for a part of the white light L emitted by the M point, and the other part of the white light L is emitted by the R color filter film and the B color filter film. Or lost in the box gap 14, resulting in a reduction in white light utilization
