Problems solved by technology

WOLED uses a white light device as a light source. The general method used is a blue-yellow two-color device, which is combined with a color film to achieve a color picture. However, the transmittance of the color film is lost, and the color gamut is limited by the light source spectrum of the white light device.

Embodiment Construction

[0034] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0035] Such as figure 2 , image 3 As shown, a substrate 201 is provided, and a first pixel region 202 and a second pixel region 203 are arranged on the substrate 201. The first pixel region 202 includes a red sub-pixel region "SPr" and a green sub-pixel region "SPg". and a white sub-pixel area "SPw", the second pixel area 203 includes a blue sub-pixel area "SPb". The first pixel region 202 is arranged on the nth row, and the second pixel region 203 is arranged on the n+1th row, where n is a natural number greater than or equal to 1. Preferably, the red sub-pixel regions "SPr", white sub-pixel regions "SPw" and green sub-pixel regions "SPg" are arranged alternately in the adjacent first pixel regions 202 . Each sub-pixel area inclu...

Abstract

The invention provides an organic light-emitting display device. Specific layout is carried out on pixels, the hole size of the adopted vacuum evaporation mask plate is increased greatly, under the same mask plate design standards, a higher-resolution pixel design standards can be more applicable, and thus manufacturing of the display device of higher resolution can be realized. On the premise that the technology complexity and the processes are not increased, four-color display can be realized through using three-color stacking, and defects of blocked holes, deformation and the like of the mask plate can be reduced.

Description

technical field [0001] The invention relates to the field of flat panel display technology, in particular to an organic electroluminescent display (OLED) device and a mask plate specially used for the display device. Background technique [0002] OLED, that is, Organic Electroluminescence Display (OLED), also known as Organic Light-Emitting Diode (Organic Light-Emitting Diode). OLED display technology is different from traditional LCD display methods. It does not require a backlight, and uses very thin organic material coatings and glass substrates. When an electric current passes through, these organic materials will emit light. And the OLED display screen can be made lighter and thinner, with a wider viewing angle, which can significantly save power. An OLED is composed of a plurality of light-emitting pixels arranged in a matrix structure. For a color OLED, each light-emitting pixel includes red sub-pixels, green sub-pixels and blue sub-pixels. For WOLEDs, it may also in...
