Abstract

The invention discloses an adjusting method of a display picture, a display panel and a display device. The adjusting method comprises the following steps that a display mode switching instruction isreceived; a first brightness value of a first pixel in a display area in a current first mode is acquired, and a second brightness value of the first pixel in a second mode to be switched to is determined; the display area comprises a fingerprint identification area and a picture display area surrounding the fingerprint identification area, and the first pixel is positioned in the picture displayarea; according to the first brightness value and the second brightness value, a brightness compensation coefficient of the picture display area in the second mode is determined; and the display modeis switched, and in the second mode, the brightness compensation coefficient is used for displaying a picture after compensating the brightness of the display area of the picture. Before the display mode is switched, the brightness of the display picture is prevented from abrupt change by compensating the display picture of the second mode to be switched, and thus the viewing effect is ensured.

Description

technical field [0001] The invention relates to the technical field of display machines, in particular to a method for adjusting a display screen, a display panel and a display device. Background technique [0002] With the popularization of smart phones, display devices with large screen ratios have attracted more and more attention. By building the fingerprint recognition function into the display screen, the space occupied by the fingerprint recognition module on the front of the mobile phone can be saved, which greatly increases the screen-to-body ratio. At present, most of the under-screen fingerprint recognition applications are designed based on the OLED display, mainly because the OLED display supports self-illumination display, and the self-luminescence can be transmitted to the fingerprint recognition sensor (Sensor ), and read the fingerprint information formed by optical reflection through the Sensor. [0003] However, there are still certain problems in the pr...
