Under conditions of same area, in upper table of the picture pixel quantity that the upper surface of oled substrate 102 can be presented than slope structure
The picture pixel presented on face 202 is more, that is to say, that the pixel resolution on the upper surface of oled substrate 102
It can be higher than the pixel resolution in the upper surface of slope structure 202.
As shown in figure 3, Fig. 3 is the sectional view of oled substrate 102 and slope surface material layer 201.Due to the slope surface material layer
The surface area of 201 upper surface 202 is bigger than the area of the upper surface of oled substrate 102, therefore, can be by more films
The electronic components 301 such as transistor (Thin Field Transistor, TFT), capacitor, line are arranged in the slope surface material layer
On 201 upper surface 202, after projection, picture that the electronic component on the upper surface 202 of slope surface material layer 201 is presented
It can completely be projected on the upper surface of oled substrate 102, the resolution of display can thus improved, display effect
More preferably.
In the specific implementation, aforesaid substrate can be touch base plate either display base plate.
Based on same creating conception, the utility model embodiment provides a kind of display device, including aforesaid substrate, described aobvious
Showing device can be applied to VR show equipment, mobile phone, computer, TV, any product having a display function such as display or
Component.Since the principle that the display device solves the problems, such as is similar to aforesaid substrate, the implementation of the display device can be found in institute
State the implementation of substrate.
It, can from above-described embodiment as can be seen that a kind of oled substrate and OLED display of the design utility model
It, will by the way that a slope structure is arranged on the surface of original oled substrate on the basis of existing manufacturing equipment and manufacturing process
