The developmental discuss of the indoor LED screen

   With today's rapid progress in technology,indoor hd display technology and the market has begun to enter into an age which has diversification of products and solutions,cross-border applications and fierce competition, indoor high-density screen display technology and the market structure is undergoing tremendous changing.

Indoor LED display market present situation:

    In recent two or three years, indoor high-density screen display technology and the market structure is undergoing tremendously changing.2009 years ago, indoor large screen is projection display technology as the core, basically mainly with DLP projection, edge fusion splicing wall, large size as the main solution.09 from the appearance of samsung ultra narrow side LCD assembly panel, then SHARP, LG, auo join the display camp, flat assembly display the meteoric rise of rapidly in various application areas of large screen display.in 2011,flat stitching and DLP joining together into the comprehensive competition stage.However,market pattern have a further change, high-density LED display strongly enter into indoor large screen display market competition.Guangzhou LED fair in February 2012, the guangzhou silicon core with 1.9 mm high density LED display unit, after two months, leyard photoelectric announced 1.6 mm products in May ,after one month, this record is refresh again by unilumin , in June this company announced will produce 1.4 mm high density LED display unit.

Because of falling prices and customer pursuit for hd display, P3 display products in 2013 promoted to one of the mainstream produxcts in indoor display.Indoor LED display develop with the direction high-resolution,and has play a great role in promoting,SMD lamp beads 2020 as the main device display effect arises at the historic moment.

LED lamp beads affect the quality of indoor LED display screen

     LED lamp bead is the most key of indoor LED display device, the quality of indoor LED display screen plays a very important role in indoor LED scree.LED display adopts the largest number led display lamp beads,every square metre can have thousands or even tens of thousands of LED lamp beads,LED lamp beads directly determine the display performance, color saturation and clarity of indoor LED display screen.

A, indoor led screen brightness

    The brightness of the LED lamp beads determine the brightness of the indoor LED display,the brighter LED lamp bead brightness is,the greater the allowance of using current is,it is good to save electricity, to keep the LED lamp beads good stability.LED lamp beads value has a different point of view, in the case of chip brightness is set, the smaller the Angle, the LED lamp bead, the brighter the screen view.Generally should choose the brightness 100 to 110  LED lamp bead to ensure indoor LED display screen enough viewing angle.

B)LED indoor display failure rate

    Indoor LED screen is composed of tens of thousands or even hundreds of thousands of LED lamp bead, LED lamp bead failure rate even if  aging 72 hours it will not higher than one over ten thousand .

C)LED indoor display attenuation characteristics

    LED lamp beads with time going by,brightness will slowly decrease.LED lamp beads attenuation speed relate with and LED chips, auxiliary materials, encapsulation process .in LED lamp beads  red, green, and blue chip attenuation to the consistency of the indoor LED display screen has great influence on the future hite balance , thus affecting indoor LED display screen display fidelity.

D)LED indoor display anti-static ability

     Due to the LED lamp bead is a semiconductor device, sensitive to electrostatic, easily lead to static electricity failure. therefore,antistatic ability is very important to the spanlife of the indoor LED display screen, generally speaking, the LED lamp bead model of human body electrostatic voltage test failure should not be less than 2000 v.
Indoor LED display screen after 10 years of rapid development have  higher and higher demand for display.in the market has a batch of encapsulation strength of the company, including the listed company, the starlight, lehman photoelectric etc, also there is new companys, zhejiang Internet to the photovoltaic, crystal, etc.

E)future development trend of LED indoor display

    Indoor LED display screen market potential is huge, with the industry standard appearance on stage,as well as companies focus on product quality, there will be more high quality and high-definition indoor LED display screen, gradually replace the original low quality screens.High-end LED display screen will be indoor LED enterprise core products in the future.
   Throughout the LED in the domestic developmental trend,LED industry has experienced a "smooth - development - peak - trough - mature period" five stages.At present, the domestic LED display industry competition level is still in its early competition,product competition key indicators embodied in: price, quality, delivery time, after-sales service,at present price is particularly prominent factors.with markets gradually get mature,after a period of market baptism, evolution, after leaving will be have the financial strength and technical strength of the company, these have a strength of the company will speed up the pace of research and development of high definition, high density of new products, is bound to clear the indoor LED display screen into a higher and more density in the new stage.
