Paper Title:
Comparison and Research of LED Screen’s Image Quality Optimizing Technology
  Abstract

This paper compares and analyzes various common sub-pixels layouts in the outdoor LED (Light Emitting Diode) display industry. According to the basic principles of chromatics and the instructions about central wavelength of LED lamps, proposed that the ratio (2:1:1) of the red, green, blue lamps in one display unit of the 4-subpixels arrangement should be changed to 1:2:1 to improve the clarity of the screen. Besides, to solve the chaotic situation of relating technologies, the paper proposed that optimizing technologies of image quality around LED screen can be classified into two groups based on sub-pixels layouts---centralizing and dispersing evenly.
