7, gray Shandong full color pixel emits light gray is the degree of shading, Shandong led display a color of gray generally 8-1024. For example sunshine p4 full-color, Linyi LED display if each color of gray to 256 p4 sunshine full color, Shandong color screen color screen for dual-color full-color p4 sunshine, its display color is 256 × 256 = 64K colors, Shandong indoor full color screen, also known as the 256-color display. 8, dual-color full color Most of today's Jiangsu color LED display is a two-color color screen, full-color Shandong hotel that is, each pixel has two LED dice: one for red dice, one for green dice.

LED Disadvantages: high initial costs, poor color, high power LED inefficient Shandong full-color, constant-current drive (need special driver circuit). In contrast, Linyi LED display a variety of traditional lighting there are some flaws. Incandescent: low electro-optical conversion efficiency (about 10%), short-lived (LED display around 1000 hours), the heating temperature is high, a single color and color temperature is low; Fluorescent: Shandong monochrome screen electro-optical conversion efficiency is not high (about 30%) harm the environment (mercury and other harmful elements, about 3.5-5mg / only), non-adjustable brightness (Shandong LED display low voltage unable starter light), ultraviolet radiation, flicker, slow start, rare earth raw material prices (fluorescence Powder accounting cost share from 10 per cent to Jiangsu full color 60 ~ 70%), repeatedly switch affect life; bulky. p4 full color | Yasuhiro photovoltaic (Online) | sunshine full color provided by the Thai-Hong Electronics Co., Ltd.
