Abstract

The embodiment of the invention discloses a control method, a control device and a control system of a mirror display device, relating to the field of display technology, so that the brightness of the display screen and the brightness of the reflection screen of the mirror display device change simultaneously with the brightness information of the viewing environment. The control method of the mirror display device includes: sensing the brightness information of the viewing environment; calculating the brightness of the display screen and the brightness of the reflection screen according to the brightness information; controlling the brightness of the display screen and the reflection screen of the mirror display device according to the calculation result brightness.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a control method, a control device and a control system of a mirror display device. Background technique [0002] The mirror display device is a new type of display device, which can not only display images, but also reflect pictures. [0003] Ordinary display devices include a first polarizing plate on one side of the array substrate and a second polarizing plate on one side of the color filter substrate, while mirror display devices also include a film with a brightness-enhancing film between the first polarizing plate and the second polarizing plate Polarizing plate (abbreviated as APCF). The light emitted by the backlight module sequentially passes through the first polarizer, the polarizer with a brightness-enhancing film, and the second polarizer to display the picture. The first plate is reflected by the polarizer with a brightness-enhancing film, causing it to re-emit ...
