Organic light-emitting displayer and manufacturing method of organic light-emitting displayer

Abstract

The invention relates to an organic light-emitting displayer which comprises a driving element array substrate, an organic light-emitting element layer and a reflecting layer. The organic light-emitting element layer comprises a first electrode layer, an organic light-emitting functional layer and a second electrode layer, the first electrode layer, the organic light-emitting functional layer and the second electrode layer are sequentially formed on the driving element array substrate, and a light outgoing area is defined by the organic light-emitting functional layer. The reflecting layer is located outside the light outgoing area of the organic light-emitting functional layer and arranged in the driving element array substrate, or the reflecting layer is located between the organic light-emitting element layer and the driving element array substrate, or the reflecting layer is located in the organic light-emitting element layer. The organic light-emitting displayer has the good mirror surface effect and the good image displaying effect at the same time. The invention further relates to a manufacturing method of the organic light-emitting displayer.

Description

technical field [0001] The invention relates to an organic light-emitting display, in particular to an organic light-emitting display with a mirror function and a manufacturing method thereof. Background technique [0002] Organic light-emitting diode (OLED) display, also known as organic electroluminescence display (OELD) or organic light-emitting display, compared with traditional liquid crystal display (liquid crystal display, LCD), does not require The additional light source (backlight) has excellent characteristics such as thinness, self-illumination, low power consumption, and wider viewing angle. It has been used in the display technology of electronic equipment, especially portable electronic equipment, and has received extensive attention. According to the driving method, the OLED display can be classified into an active matrix organic light emitting display (AMOLED) and a passive matrix organic light emitting display (PMOLED). According to the light emitting ...

Problems solved by technology

In theory, figure 2 and image 3 The OLED displays 100a and 100b have good mirror effects and image display effects at the same time, but in the actual manufacturing process, when the glass substrate 140 and the active element array substrate 110 are bonded and sealed, there will be light-transmitting openings 142a / 142b and Difficult Alignment of Organic Light Emitting Elements 132

image 3 Although the OLED display 100b increases the size of the light-transmitting opening 142b of the glass substrate 140, although the alignment difficulty is reduced to a certain extent, the area of ​​the reflective film 141b is also reduced, which not only reduces the reflectivity and affects the mirror effect, It will also affect the image display effect

[0006] Therefore, the quality of the existing OLED display with mirror function needs to be improved urgently.
