(1) selection of the operating temperature between -40 ℃ ~ 80 ℃ industrial grade integrated circuit chip, the winter temperature is too low to prevent the four-way LED display chip can not be started; (2) In order to ensure that in the case of strong ambient light away Distance visual, you must use ultra-high brightness light-emitting diode Stone; and (3) use the new wide viewing angle display media tube, wide angle, Stone chips, pure color indoor led display, led display consistent coordination, life over 100,000 hours. Display outer packaging for the media with the most popular cover along the square tube, silicone seal, metal-free assembly; its exquisite appearance, durable service led display, with anti-direct sunlight, dust, water, high temperature anti-short circuit "Five Anti" feature; smart display uses blue and Avago HCMS-29XX intelligent display of yellow, orange light, red and green product the same ASIC led display installation, and package size and lead Foot arrangements and HCMS-29XX series of the same, which uses 5x7 dot matrix serial interface. These high-performance dot matrix display via the built-in circuit board CMOS chip-driven, and each display can be connected directly to a microprocessor or microcontroller, eliminating the need for additional interfaces of the device. Serial interface can bring more display of words with minimal connection lines, using common easy to read 5x7 pixel display format can also display case Roman letters, katakana characters and other symbols or defined by the user's own . These displays are designed Blu-ray can be vertical or horizontal stack, the number of characters for use in multiple display applications. led display _ 金锐光 electricity (certified) _ yuan'an led display provided by the Science and Technology Co., Ltd.
