Embodiment Construction

[0046] Please refer to Figure 5 , Figure 5 It is a partial cross-sectional schematic diagram of an organic light emitting display panel 100 according to the first embodiment of the present invention. Such as Figure 5 As shown, the organic light emitting display panel 100 of the present invention includes a substrate 102, the substrate 102 is an insulating substrate made of a light-transmitting material, usually a glass substrate, a quartz substrate or a plastic substrate, and the substrate 102 The surface further includes a thin film transistor region 103 . A conductive layer 104 is disposed on the surface of the substrate 102 and covers the entire thin film transistor region 103 or a part of the thin film transistor region 103 . The conductive layer 104 includes a metal layer, an indium tin oxide layer (ITO layer) or an indium zinc oxide layer (IZO layer). A dielectric layer 106 is disposed on the surface of the substrate 102 and covers the conductive layer 104 , and a...

Abstract

The invention discloses an organic illumination display panel which comprises a substrate for defining a plurality of pixel zones, wherein each pixel zone defines a thin film transistor area, a conductive layer arranged in a portion of each thin film transistor region, a thin film transistor containing a grid electrode arranged in each thin film transistor region, and at least a dielectric layer arranged between the conductive layer and the grid electrode, the conductive layer, the grid electrode and the dielectric layer construct a capacitor.

Description

technical field [0001] The present invention relates to an organic electroluminescent display panel, in particular to an organic electroluminescent display panel that improves unevenness of light emission by increasing the utilization rate of layout area. Background technique [0002] Among flat-panel displays, organic light-emitting diode displays started later than liquid crystal displays (LCDs), but they are characterized by self-illumination, wide viewing angles, fast response, low power consumption, strong contrast, high brightness, thin thickness, and full-color display. The advantages of modernization, simple structure, and wide operating temperature range have gradually attracted attention in the field of small and medium-sized portable displays. Especially after persistent research and development by the industry and academia, some problems that could not be solved before, such as high process defect rate, poor mask application, unstable cap seal operation, etc., ha...
