Problems solved by technology

But when the screen is far away from the user, even if the resolution does not meet the above-mentioned resolution, the user will not be able to distinguish the pixels, so there is no need to keep the display at a higher resolution and cause excessive power consumption

Abstract

The present invention relates to a distance sensing substrate, a display apparatus, a display system and a resolution adjusting method. The distance sensing substrate comprises: a particle emitter, used for emitting a first particle beam to a viewer; a particle receiver, used for receiving the first particle beam reflected by the viewer; and a processing unit, used for acquiring energy density of the emitted first particle beam and energy density of the received first particle beam. By means of the technical scheme provided by the present invention, a resolution of a display screen can be adjusted according to a viewing distance from the viewer to the display screen, and when the viewing distance of a user is relatively large, the resolution of the display screen is appropriately reduced, so that electricity consumption of the display screen is reduced while ensuring viewing effects of the user.

Description

technical field [0001] The present invention relates to the field of display technology, in particular, to a distance sensing substrate, a display device, a display system and a resolution adjustment method. Background technique [0002] High PPI (PixelsPerInch, the number of pixels per inch) has always been an important goal in the display field, and once became an important selling point of mobile phones, TVs and other products. However, high PPI brings advantages such as good viewing effects, but also brings some disadvantages , High PPI will cause GPU (Graphics Processing Unit, display chip) to process more data, resulting in high battery power consumption. [0003] In fact, the resolution of the human eye is not static, and generally changes at any time according to the distance, environment, and image speed. One of the important theories is the "retina" standard proposed by Apple. When the viewer is 10-12 meters away from the display Inches (about 25-30 centimeters), ...
