Description
Technical field:
The utility model belongs to the information display technology field, relates to a kind of light emitting diode display board, but the light emitting diode display board that specifically a kind of single-point is changed.
Background technology:
Electronic display is to be display material with the light emitting diode, in conjunction with the high brightness flat panel display equipment of Computer Control Technology and image processing techniques.Light emitting diode is called for short LED, so electronic display claims LED display again.
LED display is that the display unit by several splicings capable of being combined constitutes the screen body, and suitable control system constitutes to add a cover.
Display unit is the main part of display screen.According to the difference of LED display installation site, the display unit of indoor display screen and outdoor display screen is different, and indoor display screen is the unit display board of all size, and outdoor display screen is that the unit shows casing.
The structure of unit display board is made of plastic reflective cover 1, light emitting diode 7, substrate electronic circuit board 2, contact pin connector 11, display driver circuit plate 3 as shown in Figure 1.Spacer pin 4 is arranged, spacing hole 6, fixed leg 5 on the plastic reflective cover 1.The effect of spacer pin 4 is the height in the spacing picture element module, guarantees the height consistance between the interior light emitting diode 7 height consistance of picture element module and each picture element module.Position, the shape of the position of the spacing hole 6 on the plastic reflective cover 1, shape and single light emitting diode 7 fit like a glove, limit the position of light emitting diode 7 corresponding plastic reflective covers 1, the interior discrete red, green, blue light emitting diode 7 of pixel is evenly distributed, the position impartially, not oblique, guarantee that simultaneously same picture element module interior pixel point arranges evenly.The quantity of spacing hole 6 is by the quantity decision of picture element module interior pixel point, and the shape of spacing hole 6 is by discrete red, green, blue light emitting diode 7 quantity of forming pixel, shape, encapsulation and arrangement mode decision.Fixed orifice 8 is arranged on the substrate electronic circuit board 2, and self-tapping screw 9 is tightened onto on the fixed leg 5 of plastic reflective cover 1 by fixed orifice 8, and plastic reflective cover 1 is fixed on the substrate electronic circuit board 2.The effect that substrate electronic circuit board 2 plays fixing light emitting diode 7 and the control line of light emitting diode 7 pixel arrays is drawn.Unit pad group 10 on the substrate electronic circuit board 2 is corresponding with the pixel array, as shown in Figure 2, the number of pad is by the number decision of light emitting diode in the pixel 7 in each unit pad group 10, if each pixel is made up of one red, one green, blue three light emitting diodes 7, the quantity of pad is six in the unit pad group 10 so, and pad is fixed a light emitting diode 7 in per two unit pad groups 10.Deposited copper conductor is arranged, as shown in Figure 3 on the substrate electronic circuit board 2.Common row conductor 13 connects the positive pole of red, green, blue light emitting diode 7.Column wire 14 connects red light emitting diodes 7 negative poles, and column wire 15 connects blue LED 7 negative poles, and column wire 16 connects green LED 7 negative poles.During welding the positive and negative electrode of light emitting diode 7 is welded on the correspondence position of corresponding color of unit pad group 10.
Each common row conductor 13 and each column wire 14,15,16 are connected respectively on the pad of contact pin connector 11 by the circuit board cabling on the substrate electronic circuit board 2, and contact pin connector 11 is welded on the anchor pad 12 of display driver circuit plate 3.Each contact pin of contact pin connector 11 is corresponding one by one with each pad of anchor pad 12.
The problem that this traditional unit display panel structure exists is:
(1) need to change when light emitting diode is bad, during maintenance, earlier the unit display board is disassembled from the screen body, again the picture element module that problem light emitting diode place is arranged is welded from display driver circuit plate 3, turn on self-tapping screw 9 with screwdriver, unload plastic reflective cover 1, could change, keep in repair light emitting diode.Maintenance process complexity, difficulty are big, maintenance speed is slow, and maintenance process easily causes picture element module and display driver circuit plate 3 to damage;
(2) single light emitting diode is a bit bad scraps a module, even scraps a module unit display board, and the scrappage height causes the LED display cost to increase;
(3) LED display is a multiple spot battle array composition, particularly large tracts of land full-color LED display screen, and hundreds of thousands, up to a million single light emitting diodes are formed, the display effect of the whole screen of some harmful effects.Safeguard that workload is big, the spare part amount is big, maintenance cost is high if press traditional structure;
Summary of the invention
Problems such as the maintenance difficulty that exists for solution conventional elements display board is big, maintenance cost height, the utility model adopts the method that increases the maintenance through hole on the display driver circuit plate, but purpose provides a kind of light emitting diode display board of single-point replacing.
The utility model as shown in Figure 5, include: plastic reflective cover 1, substrate electronic circuit board 2, contact pin connector 11, display driver circuit plate 3, it is characterized in that having increased on display driver circuit plate 3 maintenance through hole 18, the position of maintenance through hole 18 is corresponding one by one with self-tapping screw 9.
The utility model has adopted the structure that increases maintenance through hole 18 on display driver circuit plate 3, when changing bad light emitting diode 7, needs or not the removable unit display board and from unit display board dismounting picture element module, only need be from the back side of unit display board, turn on self-tapping screw 9 on the picture element module with screwdriver by the maintenance through hole 18 on the display driver circuit plate 3, take off plastic reflective cover 1, from the front of picture element module respective leds 7 is that bad light emitting diode 7 is changed under the available flatiron weldering, plastic reflective cover 1 is installed in maintenance then in reverse order.The scene can be keeped in repair, and has simplified maintenance procedure greatly.
The utility model provides a kind of unit display board mounting structure of easy and simple to handle, convenient for maintaining, can realize a bit bad replacing single-point of light emitting diode, reduces maintenance difficulties and maintenance cost, makes maintenance and changes efficient and improve greatly.
