Abstract

The invention relates to a display device, a display system and a resolution adjustment method. The display device comprises a display screen, a distance sensor and an adjustment unit, wherein the distance sensor comprises a particle emitter for emitting a first particle beam to an observer and a particle receiver for receiving the first particle beam reflected by the observer; and according to the energy density of the emitted first particle beam and the energy density of the received first particle beam, the adjustment unit adjusts the resolution of the display screen. According to the technical scheme of the invention, the resolution of the display screen can be adjusted according to the observation distance between the observer and the display screen, and when the user observation distance is large, the resolution of the display screen can be reduced properly, and the power consumption amount of the display screen is reduced on the premise of ensuring user observation effects.

Description

Technical field [0001] The present invention relates to the field of display technology, and in particular, to a display device, a display system and a resolution adjustment method. Background technique [0002] High PPI (Pixels PerInch, the number of pixels per inch) has always been an important goal in the display field, and once became an important selling point for mobile phones, TVs and other products. However, high PPI brings good viewing effects and other advantages, but also brings some drawbacks. , High PPI will lead to GPU (Graphics Processing Unit, display chip) processing data increase, resulting in battery consumption. [0003] In fact, the resolution of the human eye is not static. It generally changes at any time according to distance, environment, and image running speed. One of the important theories is the "retina" standard proposed by Apple. When the viewer is 10-12 from the display In inches (approximately 25-30 cm), as long as the resolution of the display scr...
