Abstract
The utility model discloses an outdoor LBD display module with surface mount technology, which comprises a surface-mounted structure LBD 5, a waterproof sealing layer 6, a printed wiring board 7, a drive 8 and a pedestal 9. The LBD 5 is encapsulated in rank with PLCC (plastic leaded chip carrier) with thickness more than 2.3mm to shape a picture element matrix with M lines is multiplied by N rows (M and N are positive integer). The display model can be tricolor, bicolor or single color. Compared with traditional surface-mounted LBD display module, the display module's waterproof sealing layer can be accordingly thickened due to enhanced LBD thickness to ensure waterproof sealing performance and application to outdoor environment.
Description
One. technical field
The utility model relates to a kind of light-emitting diode display module, and especially relating to a kind of light emitting diode with the surface-adhered type structure is the display module of display media, and the display screen assembled by this module can be applicable to outdoor environment.
Two. background technology.
Present light-emitting diode display module both domestic and external is pressed the difference of light-emitting diode pipe shell encapsulating structure, can be divided into perforation plug-in type light-emitting diode display module and surface attaching type light-emitting diode display module.Perforation plug-in type light-emitting diode display module exists that packing density is low, packaging efficiency is low, the defective of assembly precision difference, and assembly precision missionary society causes the module brightness uniformity to descend.
Though and traditional surface adhesive type light emitting diode display module has the packing density height in the application, the advantage that assembly precision is good, packaging efficiency is high.But because the light-emitting diodes tube thickness is thin excessively, the waterproof technology performance difficulty, outdoor utility is restricted.
More than two class light-emitting diode display modules owing to aspect different, exist different defectives, cause its result of use and range of application all to be subjected to very big influence.
Three. summary of the invention
The purpose of this utility model is improved above-mentioned light-emitting diode display module, a kind of packing forms that adopts plastic tape lead-in wire chip carrier is provided, and (english abbreviation is: Surface Mount light emitting diode (Fig. 1) PLCC-PlasticLeaded Chip Carrier) is the display module of display media, this Surface Mount light emitting diode is usually by base of ceramic 1, electrode 2, tube core 3 and reflector 4 are formed, the Surface Mount light emitting diode that is used for display screen with tradition is compared, its difference is: it has improved the thickness of light emitting diode, and promptly the surface-mount type light emitting diode is along the thickness of detector of luminous normal.After the light-emitting diodes tube thickness improved, the waterproof sealing layer of module can correspondingly be thickeied, and water resistance is protected, and can be applicable to outdoor environment.
Its technology of the utility model is achieved in that
See Fig. 2, comprise the structure of light emitting diode 5 (plastic tape lead-in wire chip carrier package, thickness are greater than 2.3mm), waterproof sealing layer 6, printed wiring board 7, driver 8 and the pedestal 9 of surface-adhered type structure, it is characterized in that: the packing forms of light emitting diode is a plastic tape lead-in wire chip carrier (english abbreviation: PLCC), thickness is greater than 2.3mm; This light emitting diode arranged mount, constitutes M capable * picture element matrix of N row, M, N is positive integer, this display module can be three primary colours, can be dual base color, also can be monochrome.
The obvious advantage of implementing after this technology is:
The Surface Mount light emitting diode of this plastic tape lead-in wire chip carrier package is compared with traditional Surface Mount light emitting diode, its thickness is increased, display module with this light emitting diode is compared with conventional surface mounted type display module, because the raising of light-emitting diodes tube thickness, the waterproof sealing layer of module is corresponding can be thickeied, water resistance is protected, and can be applicable to outdoor environment.
Four. description of drawings
Fig. 1 is the light-emitting diode structure synoptic diagram of plastic tape lead-in wire chip carrier package;
Wherein, 1-base of ceramic, 2-electrode, 3-tube core, 4-reflector.
Fig. 2 is a kind of structural representation of light-emitting diode display module of monolithic printed wiring board structure;
Wherein, 5-light emitting diode, 6-waterproof sealing layer, 7-printed wiring board, 8-driver, 9-pedestal.
Five. embodiment
Display module can adopt monolithic printed wiring board structure, also can adopt two printed wiring board structures.The utility model is further described with the light-emitting diode display module of a kind of 16 row * 16 row picture element matrixs, monolithic printed wiring board structure below in conjunction with Fig. 2:
See Fig. 2, the structure of display module is to arrange the light emitting diode 5 that mounts plastic tape lead-in wire chip carrier package in the front of printed wiring board 7, constitutes the picture element matrix of one 16 row * 16 row; Driver 8 and other device are housed at the back side of printed wiring board 7; Printed wiring board 7 after assembling finished is embedded in the modular substrate 9; Be provided with waterproof sealing layer 6 between printed wiring board 7 and light emitting diode 5, the thickness of waterproof sealing layer 6 is advisable with the pin that covers light emitting diode 5.
See Fig. 2, the application surface mounting technology mounts a kind of light emitting diode 5 of plastic tape lead-in wire chip carrier package in the front of printed wiring board 7; Driver 8 and other device are housed at printed wiring board 7 back sides; The printed wiring board of finishing after the assembling 7 is fixed in the pedestal 9; Again this assembly debugged, worn out; From light emitting diode 5 positive embedding waterproof and sealing materials, form waterproof sealing layer 6 then, thereby constitute the light-emitting diode display module of a kind of 16 row * 16 row picture element matrixs, monolithic printed wiring board structure.As a plurality of these module spliced are dressed up rectangle, equipped again Switching Power Supply, framework, control system promptly constitute a complete light emitting diode (LED) display screen.
