[0032] image 3 It is an example diagram of the display substrate of the first embodiment of the present application; Figure 4 for image 3 An example diagram of the cross-section in the direction of A-A. Such as image 3 and Figure 4 As shown, the display substrate provided in this embodiment includes: a peripheral display area ( image 3 The area outside the dotted line box) and the central display area ( image 3 area within the dashed box). Wherein, a plurality of first pixel units 23a are regularly arranged in the peripheral display area, and a plurality of second pixel units 23b are regularly arranged in the central display area.

[0033] In this embodiment, the pixel density of the first pixel unit 23a in the peripheral display area is greater than the pixel density of the second pixel unit 23b in the central display area. Such as image 3 As shown, the distance (eg, D1) between adjacent first pixel units 23a in the peripheral display area is smaller than the ...

[0052] This embodiment is an extension of the aforementioned first embodiment. The main structure of the display substrate in this embodiment is basically the same as that of the aforementioned first embodiment. The difference is that the area of ​​the first pixel unit 23a in the peripheral display area is larger than that Areas of the second pixel units (for example, the second pixel units 23b and 23c) within the region.

[0053] Such as Figure 6 and Figure 7As shown, in this embodiment, the area of ​​the first pixel unit 23a in the peripheral display area is larger than that of the second pixel unit in the central display area, and the distance between adjacent first pixel units 23a in the peripheral display area (such as , D1) is less than the distance between adjacent second pixel units in the central display area (for example, D2 or D3), so that the pixel density of the first pixel unit in the peripheral display area is greater than that of the second pixel unit in the...

[0058] Figure 8 It is an example diagram of the display substrate of the third embodiment of the present application; Figure 9 for Figure 8 An example diagram of the cross-section in the direction of A-A. Such as Figure 8 and Figure 9 As shown, the display substrate provided in this embodiment includes: a peripheral display area ( Figure 8 The area outside the dotted line box) and the central display area ( Figure 8 area within the dashed box). Wherein, a plurality of first pixel units 23a are regularly arranged in the peripheral display area, and a plurality of second pixel units 23b and second pixel units 23c are regularly arranged in the central display area. Wherein, the area of ​​the first pixel unit is larger than the area of ​​the second pixel unit, and the pixel density in the peripheral display area is equal to the pixel density in the central display area.

[0059] Such as Figure 9 As shown, the display substrate includes a substrate 20, a driving str...

Abstract

The invention provides a display substrate comprising a peripheral display area and a central display area. A plurality of first pixel units are regularly arranged in the peripheral display area, anda plurality of second pixel units are regularly arranged in the central display area. The pixel density of the first pixel units in the peripheral display area is greater than the pixel density of thesecond pixel units in the central display area, or the pixel density of the first pixel units in the peripheral display area is equal to the pixel density of the second pixel units in the central display area, and the area of the first pixel units is greater than the area of the second pixel units. The invention also provides a preparation method of the display substrate and a display device comprising the display substrate.

Description

technical field [0001] This article relates to the field of display technology, especially to a display substrate, a manufacturing method thereof, and a display device. Background technique [0002] Organic Light-Emitting Diode (OLED, Organic Light-Emitting Diode), as a new type of light-emitting device, has shown great application potential in the field of display, so it has attracted strong attention from academia and industry. Compared with LCD (Liquid Crystal Display), OLED has the advantages of self-illumination, fast response, wide viewing angle, high brightness, bright color, light and thin, etc., and is considered to be the next generation display technology. [0003] At present, the equipment and process of making OLED products by inkjet printing method are becoming more and more mature. Among them, the materials used to make the OLED display substrate can be dissolved in a specific inkjet printing solvent to form inkjet printing ink, and the inkjet printing ink ca...
