Description
Technical field
The present invention relates to LED display fields, specially a kind of small spacing LED Intelligent full-colors glass display screen and display are single
Member.
Background technology
Intelligent full-color glass display screen is a kind of by controlling LED（Light Emitting Diode）That is light emitting diode
Using transparent glass as the display screen for being used for showing the various information such as word, figure, image, video of substrate.With traditional technology
Have that transparency is high, operating voltage is low, performance is stable compared to LED display and can the good characteristics such as enlargement, although intelligent
LED glass display screen technologies have been rapidly developed, but still fall within the primary stage of industrial design and study on the industrialization.
Traditional LED full-color display screen is three conjunctions for being packaged into DIP (straight cutting) LED light with LED wafer or being encapsulated with SMD
One LED light is welded on pcb board together with the driving elements such as IC and capacitance, current-limiting resistance, decoder（Generally glass-fiber-plate）Substrate
On, then after tested, injecting glue, solid glue, aging are assembled into LED module.With P4（16*32 pixels）For module, 4 layers need to be used
Pcb board, due to the pixel of individual module it is few, splice large display screen when, the module amount needed is huge, and interface quantity is also huge,
Fault rate increases significantly.Traditional grating screen due to structural member, component number is more, size is big, the big discounting of light transmittance
Button.
In order to realize existing good light transmittance, and it can show the LED display of high-definition image effect, at home and abroad
There are some using glass as the LED display product or relevant art of carrier, is obtained such as through retrieval, number of patent application：
201410730418.8 201420478443.7,201420459519.1,201410513862.4.But related application is only
It only describes several very simple LED to use, is mostly three-in-one LED light Surface Mount in ITO（Indium Tin Oxides
Nano indium tin metal oxide）In coated glass, and the pin of lamp is connected to through ITO circuits outside glass（Pass through flexible printing electricity
Driving chip and power module are connected on glass by road plate FPC）.Since driving circuit is outside glass display screen, all LED light
Pin will lead to glass edge by ITO circuits, then pass through FPC（Flexible electric circuit board）It is connected to peripheral drive circuit and power supply
On power supply, so each glass modules interior cabling is in large scale and lead distance is longer.When electric current is plated by longer thinner ITO
When film circuit, since the sheet resistance of ITO plated films is larger（The ITO sheet resistances of common LED glass display screens：R□≥15Ω）, can because
Resistance is larger and generates heat waste, and fever can also make the image color reduction of LED display be affected.
Fig. 3 is the driving plate lateral circuit schematic diagram of certain prior art, it should be apparent that, electronic component is many on the circuit board
More, the external wire of driver is excessive, and the layout on glass is complicated so that installation is inconvenient, and LED glass screens are being used for a long time
In easily there is poor contact（Dead lamp）The problem of.External wire is excessive simultaneously, but also the point spacing of LED glass screens can not accomplish
25mm is hereinafter, be unable to get existing good light transmittance, and can show the full-color glass display screens of the LED of high-definition image effect.
Invention content
The purpose of the present invention is overcome the deficiencies of the prior art and provide a kind of LED Intelligent full-color glass displays of small spacing
Screen and LED glass display elements.
A kind of small spacing LED Intelligent full-color glass display screens, the display screen include glass substrate, and ITO plates film figure circuit,
Multiple LED die groups and multiple driving IC bare dies, each LED die group include three LED dies, and respectively red LED is brilliant
Member, green LED wafer and blue led wafer.
The ITO platings film figure circuit is made in by sputter vaporization method on glass substrate.The ITO plates film figure
The sheet resistance of the glass substrate of circuit is less than or equal to 4 ohm.
The mode that the driving IC bare dies and the LED die group are all made of upside-down mounting is pasted onto the ITO platings film figure electricity
On the road.
The driving IC bare dies are that two-wire triple channel LED constant current drives non-packed IC.
Each driving IC bare dies drive a LED die group, and are cascaded with other driving IC bare dies.
The point spacing of the LED Intelligent full-colors glass display screen can accomplish 25mm hereinafter, i.e. 0-25mm, preferably
2mm, 3mm, 3.5mm, 4mm, 4.16mm.
The size maximum for constituting the module of the display screen can be 1500mm*3500mm, and the LED die group can be by sealing
Size is filled to realize in 1mm*1mm three-in-one LED lamps below.
The driving IC bare dies have been internally integrated power-supply filter, serial decoding circuitry, pwm control circuit, LED constant current control
Circuit processed drives output circuit, shaping repeat circuit and OSC (abbreviation of oscillator) crystal oscillator.
The Intelligent full-color glass display screen also includes dedicated interface unit.
The interface unit is connected to glass display elements to restore the image of display data through transmission cable component.Institute
Transmission cable component is stated, is snapped on glass ITO circuits by a deca-cable and thin long strip type plastic cement mother socket and a row
Arrange needle and plastic cement male plug part composition.
The Intelligent full-color glass display screen does not need LED lamp bead and the driving IC with encapsulation, only need to by LED wafer and
The bare die of driving IC is inverted in low square resistance ITO（ITO sheet resistances：R□<4Ω）On glass substrate so that circuit abnormality on glass
Simply, because LED drives the pin of IC and the pin distance of LED die to be less than 100um, so several on ITO circuits of the present invention
Do not generate power consumption and temperature.It eliminates existing LED lamp bead and drives the encapsulation procedure of IC, also eliminate convention display mould
The processing of group and assembly processing procedure, due to the use of be the driving IC bare dies for being suitble to run in glass substrate, pass through upside-down mounting R, G, B crystalline substance
First Surface Mount optimizes circuit on low-resistance ito glass substrate, reduces the use of component so that glass display screen picture is drawn
Matter is more stablized, and can accomplish P4 in single circuit（Point spacing 4mm）Small spacing Intelligent full-color glass display screen below,
And module maximum can make 1500mm*3500mm, can directly replace conventional curtain wall glass, become the Intelligent full-color glass of high definition
Show curtain wall, transparency is up to 80% or more.
