Abstract

The invention relates to a display brightness adjusting device and a display device. The display brightness adjusting device comprises a first polarizer, a polarization adjusting layer and a second polarizer; the polarization adjusting layer is arranged at one side of the first polarizer, and is used for changing the polarization direction of light penetrating through the first polarizer; and thesecond polarizer is arranged at one side of a polarization direction adjusting layer away from the first polarizer. The display brightness can be adjusted by enabling the light emitted from a displaypanel to pass through the first polarizer, the polarization adjusting layer and the second polarizer, wherein the polarization state of the light emitted by the display panel changes after passing through the polarization adjusting layer, thus the brightness of the light emitted from the second polarizer can be adjusted, so that the display brightness is adjusted, and the problem that the displaydevice is stroboscopic caused by adjusting the brightness of the display device through PWM is solved.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular, to a display brightness adjustment device and a display device. Background technique [0002] With the development and progress of technology, OLED (Organic Light Emitting Diode, organic light emitting diode) display devices are more and more widely used. The OLED display device realizes display by emitting light through the light-emitting layer, and the OLED display device usually adjusts the brightness of the display device through PWM (Pulse Width Modulation) during the display process. Adjusting the brightness of the display device through PWM will cause stroboscopic flicker in the display device, and stroboscopic flicker will cause discomfort to the user's glasses, which may cause damage to the user's eyes. [0003] It should be noted that the information disclosed in the above background section is only for enhancing the understanding of the background of the p...
