Problems solved by technology

[0003] However, when the existing circular OLED display is displayed, a jagged shape will appear on the edge of the circular display area, which affects the viewing experience of the user.
In order to solve this problem, the Driver IC (drive circuit) in many OLED displays will perform pixel compensation on the edge of the circular display area to reduce the aliasing problem, but this will increase the power consumption of the Driver IC and increase the cost of the OLED display

Embodiment Construction

[0030] In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0031] At present, there are more and more demands for special-shaped displays in the market, among which there are many display products with rounded corner design, such as round watches, square displays with rounded corners, etc.

[0032] but if figure 1 As shown, when the existing circular OLED display is displayed, a sawtooth shape will appear on the edge of the circular display area, which affects the user's viewing experience. In order to solve this problem, the Driver IC in many OLED displays will perform pixel compensation on the edge of the circular display area to reduce the aliasing problem, but this will increase the power consumption of the Driver IC and increase the cost of the OLED display.

Abstract

The invention provides an OLED display substrate and a manufacturing method thereof as well as a display device, and belongs to the technical field of display. The OLED display substrate comprises a plurality of sub-pixels, wherein the sub-pixels comprise first sub-pixels located in an effective display area of the OLED display substrate and second sub-pixels located at the boundary of the effective display area of the OLED display substrate; the second sub-pixels comprise first parts located in the effective display area and second parts located outside the effective display area; and when the OLED display substrate is used for displaying, the second parts do not emit light. According to the technical scheme, a special-shaped display can be realized at a low cost.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED display substrate, a manufacturing method thereof, and a display device. Background technique [0002] At present, users have higher and higher requirements for display devices. Lighter, thinner, brighter and more energy-saving have become the requirements of most users. OLED (Organic Light-Emitting Diode) displays can realize display functions without backlight by virtue of their self-luminous characteristics. , becoming the lighter and thinner display of choice. At the same time, there is an increasing demand for special-shaped displays in the market, and there are many display products with rounded corners, such as round watches and square displays with rounded corners. [0003] However, when the existing circular OLED display is displayed, a sawtooth shape will appear at the edge of the circular display area, which affects the user's viewing experience. In order to...
