Embodiment Construction

[0013] FIG. 1 shows a top emission organic electroluminescent display known to the inventors. It should be noted that the structure in FIG. 1 is not a known technology, but is only used to illustrate the problems discovered by the inventors in the process.

[0014] The top emission organic electroluminescent display 100 shown in FIG. 1 includes an active element substrate 101 with a plurality of driving elements (not shown). There is a conductive layer 103 on the active element substrate, which is used as a contact between the pixel electrode of the organic light emitting display and the source / drain of the active element substrate 101 , and its material is copper or aluminum, for example. A dielectric layer 105 is formed on the active device substrate 101 and the conductive layer 103 , which has a contact window 107 and exposes part of the top surface of the conductive layer 103 . Formed in the dielectric layer 105 , the exposed conductive layer 103 and the contact window 107...

Abstract

A top luminous organic electroluminescent luminous display unit includes: a substrate including a display zone; a conductive layer situated above the substrate, and is electrically connected with the substrate; a reflection layer situated at the display zone of the substrate; a dielectric layer situated above the conductive layer, the reflection layer and the substrate, wherein the dielectric layer has a contact window out from the conductive layer; a transparent electrode layer situated above the dielectric layer and electrically connected along the contact window and the conductive layer; and a organic electroluminescent luminous layer situated above the transparent electrode layer, and corresponding to the display zone.

Description

technical field [0001] The present invention relates to a top-emitting organic electroluminescent display, and in particular to a top-emitting organic electroluminescent display capable of improving luminous efficiency and chromaticity. Background technique [0002] The light emitting principle of organic electroluminescent devices (also called organic light emitting diode (OLED) display) is to apply an external electric field to the organic molecular material to make it emit light. Due to its self-emission, the organic electroluminescent display can be displayed in a matrix type (dot matrix type display). It has light and thin, high contrast, low power consumption, high resolution, short response time (fast response time), and no Features such as backlight and wide viewing angle, and its panel size can range from a 4mm microdisplay to a 100-inch large outdoor billboard. It is regarded as the mainstream of the next-generation flat-panel display. An array structure is formed...
