Problems solved by technology

[0005] However, due to the existence of these transistors, the surface of the insulating layer 12 is uneven, and then the surface of the transparent electrode 14 is uneven, as shown in FIG.
As a result of increased surface roughness, materials in subsequent processes will perform poorly, which will affect the quality of organic light-emitting displays

Embodiment Construction

[0019] The spirit of the present invention is to add a flat layer on the insulating layer of the organic light-emitting display, so as to facilitate the material performance of subsequent processes. Referring to FIG. 2 , it shows a schematic cross-sectional view of an active matrix organic light emitting display according to a preferred embodiment of the present invention. Firstly, active components arranged in a matrix are formed on the substrate 20 to control the display of each pixel, which is not shown in the figure because it is well known to those skilled in the art. The insulating layer 22 is then formed. Next, a planarization layer 23 is formed on the insulating layer 22 to planarize the surface and reduce surface roughness. The flat layer 23 is an organic material, which can be coated on the surface by spin coating to obtain a flat effect. The material used for the flat layer 23 is non-absorbent and stable, such as organic material PC403, which is a product of JSR C...

Abstract

An active matrix organic light emitting display (AMOLED) includes substrate, insulation layer, flat layer, clear electrode, luminous layer and metal electrode. Flat layer is on surface through spin coating for making surface flatness in order to help to following procedures.

Description

technical field [0001] The present invention relates to an organic light emitting display (Organic Light Emitting Diode, OLED), and in particular to an active matrix (Active Matrix) organic light emitting display (AMOLED). Background technique [0002] Due to the vigorous development of flat-panel display technology, organic light-emitting displays (Organic Light Emitting Diode, OLED), compared with traditional liquid crystal displays (Liquid Crystal Display, LCD), in addition to being lighter and thinner, more self-illuminating, low power consumption, no need Excellent features such as backlight, no viewing angle limitation, and high response rate have been hailed as the mainstream of next-generation flat-panel display technology. Since the passive matrix organic light emitting display (PMOLED) cannot meet the requirements of high resolution and large size, active organic light emitting display technology is an inevitable trend. [0003] FIG. 1 is a schematic cross-section...
