Display device and manufacturing method thereof

Abstract

The invention provides a display device and a manufacturing method thereof. The display device comprises a back plate module, a pixel definition layer, a transparent conductive layer and an organic light emitting layer, wherein the back plate module comprises a TFT driving back plate and an insulation layer arranged on the TFT driving plate; the pixel definition layer, the transparent conductive layer and the organic light emitting layer are formed on the insulation layer; the pixel definition layer comprises a plurality of openings; the transparent conductive layer comprises open-area transparent conductive layers and non-open-area transparent conductive layers; the open-area transparent conductive layers are positioned in the multiple openings of the pixel definition layer; the organic light emitting layer is formed on the open-area transparent conductive layers so as to correspondingly form multiple subpixels; stereo lower sunken holes are formed in the back plate module below the subpixels of at least one color; each stereo lower sunken hole corresponds to each opening; the open-area transparent conductive layers and the organic light emitting layer are positioned in the stereo lower sunken holes. According to the display device, the space structure of a pixel area is changed, and the surface area of a light emitting area is enlarged; the scheme is suitable for various display devices, so that the current density can not be increased and the voltage and the power consumption are reduced under a condition of high PPI.

Description

technical field [0001] The invention relates to a display device and a manufacturing method thereof, in particular to a low power consumption display device and a manufacturing method thereof. Background technique [0002] The pixel arrangement in the existing AMOLED panel is generally a real pixel arrangement (Real arrangement). The structure of this arrangement is relatively simple, the layout design and mask production are more convenient, and the process production is also easier. [0003] Such as Figure 1a As shown, a conventional AMOLED panel includes a backplane module 1', a passivation layer 2', a planarization layer 3', a pixel definition layer 7', a transparent conductive layer 4' and an organic light emitting layer 6'. Wherein the passivation layer 2' is formed on the backplane module 1', and the planarization layer 3' is formed on the passivation layer 2'. The pixel definition layer 7' is formed on the insulating layer, the pixel definition layer 7' includes a ...

AI Technical Summary

Problems solved by technology

[0010] 1. The calculation display effect is not as good as Real, such as the problem of slash glitches;

[0011] 2. The circuit (IC) will become complicated and increase a lot of cost;

[0012] 3. Lack of core algorithm patents

[0014] In addition, in the prior art, as far as an AMOLED panel is concerned, the overall cross-voltage design is generally certain, so this setting must leave enough buffer for the voltage of each sub-pixel, so that the voltage of each sub-pixel can be guaranteed

In this case, the voltage of some sub-pixels exceeds the required voltage, resulting in voltage setting redundancy, and the resulting waste of power consumption will become the bottleneck of the entire setting
