Description
[technical field]
The invention relates to a kind of display unit, be meant that especially a kind of light-emitting component is arranged on the display unit on the signal circuit board (Signal Circuit Board).
[background technology]
In response to the compact requirement of hand-held electronic product at present, the signal on its display unit (for example display floater drive signal) substantially all be one as thin as a wafer signal circuit board accept.
Please refer to Fig. 1, is that a kind of display floater and signal circuit board of prior art display unit combines schematic diagram with framework.This display unit 1 comprises a signal circuit board 110, a display floater 120, a framework 130, a light guide plate 140 and two light-emitting components 100.
This signal circuit board 110 is flexible circuit board (Flexible Printed CircuitBoard), comprises one in order to the light source setting area 111 of two light-emitting components 100 to be set, and one in order to drive the main circuit district 112 of display floater.These two light-emitting components 100 are two light-emitting diodes (Light Emitting Diode).This display floater 120 is connected in the main circuit district 112 of this signal circuit board 110, and this display floater 120 is arranged on this framework 130.This framework 130 comprises a depressed part 131 and an accommodation section 132, and this depressed part 131 has two and lacks 133.This light-emitting component 100 is corresponding to breach 133.Light source setting area 111 is arranged between display floater 120 and the framework 130 in the reflexed mode simultaneously.This light guide plate 140 is arranged on this accommodation section 132.
This display unit 1 is in assembling process, earlier light guide plate 140 is arranged in framework 130 accommodation sections 132 with gummed or joggle mode, again these signal circuit board 110 light source setting areas 111 are adhered to the front of framework 130 in the gummed mode, this light source setting area 111 is adhered to the depressed part 131 of framework 130, and breach 133 shapes of depressed part 131 and light-emitting component 100 coincide, this light-emitting component 100 is embedded in this breach 133, and then, finish assembling like this with this signal circuit board 110 and display floater 120 reflexeds.
But this kind design is because light source setting area 111 needs reflexed, thus signal circuit board 110 very property must be lower.Very the lower signal circuit board 110 of property certainly will be to light-emitting component 100, and promptly difficulty is caused in effective location of light-emitting diode.Light source setting area 111 easily causes light-emitting component 100 dislocation because of shaking or clashing into, and causes the brightness of display floater 120 to descend.And because light source setting area 111 is to utilize the gummed mode that flexible circuit board is combined with framework, therefore, the viscosity of sticker must enough stick to prevent flexible circuit board resilience protuberance.If when signal circuit board 110 had the circuit element of higher density because of circuit design, the welding job of light-emitting diode also caused difficulty, influence the yield of product.
[summary of the invention]
For overcome prior art because of vibrations or bump cause light-emitting component dislocation and the problem of be inconvenient to assemble, providing the display unit of a kind of effective location light-emitting component and ease of assembly real is necessity.
A kind of display unit, it comprises a display floater, one signal circuit board and at least one light-emitting component, this display floater and this signal circuit board electrically connect, this signal circuit board comprise one in order to the main circuit district and that drives display floater in order to the light source setting area of light-emitting component to be set, this light-emitting component is arranged on the light source setting area of this signal circuit board, this signal circuit board comprises flexible circuit board and the hard circuit board that combines, this main circuit district is arranged on this flexible circuit board zone, and this light source setting area is arranged on this hard circuit board zone.
Compared to prior art, in the present invention, light-emitting component directly is integrated on the signal circuit board with the main circuit that drives display floater, and the hard circuit board that utilizes the light source setting area is light-emitting component effectively fixedly, make the display unit assembling more simple and easy, and improve process rate.

[embodiment]
Please refer to Fig. 2, is the three-dimensional exploded view of a kind of better embodiment of display unit of the present invention, and this display unit 2 comprises a signal circuit board 210, a display floater 220, a framework 230, a light guide plate 240 and two light-emitting components 200.
Please refer to Fig. 3 and Fig. 4, is front view and vertical view that the signal circuit board 210 of display unit 2 of the present invention combines with light-emitting component 200.This signal circuit board 210 is soft or hard combined circuit plates.Soft or hard combined circuit plate is that the conductive layer of a kind of flexible circuit board and hard circuit board electrically connects, be pressed on hard circuit board by flexible circuit board, and from the extended connected mode of hard circuit board, flexible circuit board and hard circuit board are integrated, and it is with the feature of flexible circuit board and hard circuit board.
This signal circuit board 210 comprises a light source setting area 211 and a main circuit district 212, and the cantilevered distal end of autonomous circuit region 212 is extended in this light source setting area 211, and is arranged on the front of this signal circuit board 210.This main circuit district 212 adopts flexible circuit board, and hard circuit board is adopted in light source setting area 211.This light-emitting component 200 combines with the light source setting area 211 of this signal circuit board 210 with welding manner.
Please refer to Fig. 5, be framework 230 floor map of display unit 2 of the present invention, this framework 230 comprises a depressed part 231, an accommodation section 232 and a slotted eye 234, and this depressed part 231 has two breach 233, in order to hold the light-emitting component 200 that is arranged on this light source setting area 211.
Please refer to Fig. 6, is light guide plate 240 floor map of display unit 2 of the present invention, and this light guide plate 240 is the flat boards at angle, cut two ends, and formed cross section, cut back, end angle is the light entrance face 241 of this light guide plate 240.
Please together with reference to Fig. 2, Fig. 7, main circuit district 212 1 ends of this signal circuit board 210 are electrically connected at this display floater 220 again.This display floater 220 is arranged on this framework 230, and this light guide plate 240 is arranged on the accommodation section 232 of this framework 230, and wherein this light-emitting component 200 is arranged between framework 230 and the display floater 220.In the present embodiment, light-emitting component 200 is a light-emitting diode.
