Problems solved by technology

In this case, the light-emitting time of the OLED corresponding to the optical fingerprint recognition area will be longer than that of the rest of the display area. The life attenuation degree of the OLED in the area will be different, which will cause the display effect of the fingerprint identification area to be inconsistent with the display effect of the rest of the display area, which will affect the visual effect.

Embodiment Construction

[0028] In order for those skilled in the art to better understand the technical solution of the present invention, the display method of the display module and the display method of the display device provided by the present invention will be described in detail below with reference to the accompanying drawings.

[0029] see figure 1 , the display module 101 includes a display area 102, the display area 102 includes a fingerprint identification area 102a disposed therein, and other areas 102b except the fingerprint identification area 102a. Moreover, in this embodiment, if figure 2 As shown, the fingerprint identification area 102b includes six sub-areas divided sequentially from the center to the boundary of the fingerprint identification area 102b, which are the 0th sub-area to the fifth sub-area. Wherein, the shape of the 0th sub-area is similar to that of the fingerprint identification area 102b, that is, a rectangle, and is located at the center of the fingerprint ident...

Abstract

The invention provides a display module display method and a display device display method. A display module includes a display area, and a fingerprint identification area is arranged in the display area. The display method includes that during the fingerprint identification, the display brightness gradually decreases from the center of the fingerprint identification area to the boundary; and during the normal display, the display brightness gradually increases from the center of the fingerprint identification area to the boundary. By means of the display module display method and the display device display method, the service life attenuation curves of the fingerprint identification area and the other display areas tend to be consistent, so that the display effects of the fingerprint identification area and the other display areas tend to be consistent, and the visual effect can be further improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display method of a display module and a display device. Background technique [0002] Compared with traditional displays, flexible OLED (Organic Light-Emitting Diode) displays are not only thinner and lighter in size, but also lower in power consumption, which helps to improve the battery life of the device. With good flexibility, its durability is also much higher than that of traditional display screens, thereby reducing the probability of accidental damage to equipment. [0003] At present, the optical fingerprint identification function of flexible OLED display is to use a certain part of the display area as the fingerprint identification area, and use the light emitted by the OLED display itself as the light source for fingerprint identification. In order to make the optical fingerprint identification function fast and stable, it is necessary to make the reflect...
