A LED screen engineer's research and Development Notes: single color era will end

In 2008 I entered the LED display industry, P16 was already very monochromatic features, P10 single red should be called luxury, mantianyaojia.

2010 P10 single red began to spread a large area of the street after seeing storefront is red, so I was born to change the door idea, so the second half of 2010 P10 single white, green, yellow, single single single blue US mass production, a time of shops along the street began brightly coloured, very beautiful.

In 2011 P10 became a popular monochrome products, there is no longer any fresh at all, special color and no longer meet the needs of customers, so, I was born to do a full color idea, so the beginning of 2011 door P16 full-color market.

For a time, like snowflakes flying orders to the company, the production line all night working overtime to produce the product; I have done a test, mobile phone on the desk top does not move, one day the peak 148 calls come to consult this product, the order is beyond count; glory after customers began to realize P16 space too big, the display for the ordinary store is very harsh, so this product also need to upgrade.

In 2013, we focused on the P10 and color of this product, as it relates to the cost is too high, the promotion difficulty, coupled with the product maintenance difficulty is high, the general customer can not maintain, so although many early orders, will gradually cool down.

2013 qianglijucai hit a new concept, P13.3 full color, the color after the actual comparison, in the current market demand situation still can not meet the needs of customers, a display point spacing is too large, so the prospect is not very obvious (in my opinion).

May 2013 began to improve and upgrade the basic P10 door full color, want a lot of ways, beginning to consider the chip maintenance difficulty, first on the abolition of the IC front drive, or drive a rear lamp, lamp drive or separation, but light flooding separation is very difficult to reduce the cost, for the promotion of high disadvantage, so the final choice light flooding one way, taking into account the intensity of the chip, decided to study 1/6 module scanning mode, the actual operation, so the operation of gray level and the refresh rate is difficult to go up, so this way also cancelled; after the final parameters than unanimously decided to take the 1/4 scan drive mode.

The highlight of this product is that he had a practical upgrade on the original platform above.

1, the original QFN package 5020 although the effect is very good, but his maintenance difficulty is very high, the peak of company customer service department that has become a maintenance problem; after improvement in the maintenance of the real meaning to repair P10 monochrome products can be the maintenance of full color P10 products.

2, product specifications are still above the 320*160 specification, the latter is expected to develop 320*320 specification module, and can share with the 320*160 module.

3, the luminous chip is still using the LED tube core Taiwan Jingyuan, R:10*10 positive, G:8*15 positive, B:9*13 positive, the entire screen brightness after spectrometer brightness greater than 6900CD/ square, from the parameter display, this product can meet the market demand of small square color engineering.

4, this product uses IC drive Taiwan accumulation of MBI5020 precision chip, the refresh rate higher, add this product unique standard QJC908 full color control system (50205024, 5041 research and development of science and technology accumulation and accumulation of chip control system), better display.

5, the upgrade process, this product production process is still using a molding plastic kit high temperature and ultraviolet radiation, low temperature, especially suitable for use in the northeast and northwest Arctic regions, and the eastern coastal Hainan and humid areas.

6, this product is still using the circuit board inside the industry is 2.1MM circuit board ultra thick copper foil, thicker lines, more stable, very helpful for IC cooling and heat radiation of the lamp tube, can adapt to the current high standards of color products, high demand!

It can be predicted that the number of single and double color more popular areas, the product is the first choice for dealers and developers to develop market products!
