Description
Technical field
The utility model is related to arrive showing stand technical field more particularly to a commodity letter based on COB display technologies
Breath publication showing stand.
Background technology
Currently, megastore or brand shop mainly use poster, promotional card to carry out products propaganda, content is single, and more
Printing cost is higher when changing content, while generating a large amount of waste paper printed matter, wastes stationery resource.
In recent years, the high-end brand shop in part and market started to introduce LCD TV, advertisement machine and LED video walls, for pacifying
Theme publicity, new product release and hot-sale products displaying etc. are done mounted in shop interiors, but due to its higher price and large area
Occupied space, general bantam shop and community shop popularization degree be not high.
About at 2015 or so, in Some European developed country, several manufacturers utilize tablet computer technology, use
LCD (liquid crystal display) does display medium, develops some and the almost small smaller advertisements display screen of mobile phone, tablet computer, compares
The products such as LCD TV, advertisement machine and LED video walls, small and exquisite external form, a small number of expenses input, have obtained rapidly majority
The favor in market, supermarket.
But as the application of market and supermarket, many problems and defect also gradually show, such as：The LCD of glass structure
Screen is easily broken, display brightness is low（It is not seen completely when about 50-150nit backlights）, LCD liquid crystal color reduction degrees it is poor（With LCD
It is reflected by liquid crystal molecule and shows that the characteristic of picture is related）Deng frangible for the market of passenger flow complexity, supermarket's environment
Inherently there is security risk in glassware, and low-light level, not bright-coloured enough picture display effect seriously affect a surname of product
Pass, promotion effect, so do not applied on a large scale, so now we the public places such as market, supermarket not
Have and sees a large amount of use.
In order to solve the problems, such as the undesirable problem of the frangible and low-light level of existing LCD display, picture display effect, need
Display terminal is replaced, in current display technology, mainly there is two kinds of LED display, LCD display, wherein LED display
Because using array mount three-color light-emitting diode, surface non-glass material, be not likely to produce it is broken, can alternately side
One of case.
In order to not influence market, the decoration style of supermarket, brand shop, it is not take up space, crack space need to be made full use of,
Ask product to minimize, by market survey, client propose display screen should be placed on Goods shelf partition plate cross section or partition board it is upper
Side, lower position, display screen height should be less than 60mm.
For the above market information, needs to make pixel spacing in PH1.5-PH2.0mm, can realize above-mentioned pixel
Resolution ratio, in conjunction with the application technology of current LED display terminals, mainly facing problems with needs to solve：
1, by the understanding to LED display technology, in the LED display product of below spacing of PH2.5mm, due to
Potted element is smaller, and using being very fragile after SMT techniques, surface when touching is susceptible to element dry joint and lamp bead falls off
Problem；
2 thus novel LED display terminal be mounted in stream of peoples' close quarters such as market, low pressure should be used（It is less than
The safe voltage of 36V）Power supply, but if power supply is external, using 5V centrally connected power supplies, then line loss will generate pressure drop,
It will cause to show that aberration and brightness are abnormal, Supply Security conflicts generation with display effect；
3 thus product needs apply it is super in brand shop, high-end quotient, it is desirable that external form is compact, and wiring is simple, does not influence in shop
Decorated style, but modules, the device such as control system, power supply, driving circuit of conventional LED display occupy larger space,
And to ensure picture display effect, the control signal of display screen is generally transmitted using gigabit network cable, thus need to solve by
The problem of this all kinds of module volume brought and signal, electrical transfer.
Therefore, the prior art is defective, needs to improve.
