Embodiment
The present invention provides a kind of safeguard structure, and this structure can be slowed down voltage-withstand test and is stressed to what backlight module caused, and reduces the fraction defective of product function.
Fig. 1 illustrates the exploded view according to a kind of flat-panel screens of the present invention's one preferred embodiment.In Fig. 1, this flat-panel screens 100 comprises preceding chase 110, display panel 120, circuit board 140, backlight module 160, safeguard structure 180 and shell on the back 198.In the present embodiment, preceding chase 110 is positioned at the demonstration side of display panel 120.(Chip on film, COF) 122 are connected with display panel 120 circuit board 140 through covering brilliant film.When 160 groups of backlight modules stand between display panel 120 and the shell on the back 198, need circuit board 140 is up dug, and be placed between backlight module 160 and the shell on the back 198.Safeguard structure 180 is covered on the circuit board 140; When receiving ambient pressure in order to lower shell on the back 198; Element on the circuit board 140 or joint generation stress are concentrated and are caused the optical element in backlight module 160 compressive deformations, particularly backlight module 160, for example are LGPs.
Fig. 2 illustrates circuit board and the safeguard structure enlarged diagram of Fig. 1.In Fig. 2, circuit board 140 has a signal link slot 142, and this signal link slot 142 has opening 144, the long axis direction approximate vertical of its opening direction 146 and circuit board 140.Safeguard structure 180 has layer protecting film 182 and a movable plate 185.First end 183 of diaphragm 182 is attached on one side of preceding chase 110; Second end 184 has two connecting bands 186, and wherein this connecting band 186 extends in the diaphragm 182 and forms a long and narrow tangent line 186a.Movable plate 185 is connected with diaphragm 182 through connecting band 186.Form a through hole 187 between two connecting bands 186 and diaphragm 182, the movable plate 185; These through hole 187 areas are slightly larger than the area of link slot 142; Can ccontainingly protrude from the signal link slot 142 on the circuit board 140 after being used to assemble, make the integral thickness of covered protection structure 180 be unlikely increase or excessively increase.And formed long and narrow tangent line 186a between connecting band 186 and the diaphragm 182 makes also can start through hole 187 in the lump when movable plate 185 is raised, and with the complete signal link slot 142 that exposes, it is conveniently connected with other element.The thickness of diaphragm 182 is as if the thickness less than signal link slot 142, and the integral thickness of signal link slot 142 after adding safeguard structure 180 can not increase.Even the thickness of diaphragm 182 is greater than the thickness of signal link slot 142, the integral thickness of signal link slot 142 after adding safeguard structure 180 can excessively not increase yet.In the present embodiment, the area of flexible member 190 and movable plate 185 about equally or smaller is arranged at the upside of movable plate 185; Flexible member 190 also can be attached at the downside of movable plate 185, and attaching side does not influence its function.Yet as long as flexible member 190 provides enough stress buffers, flexible member 190 need not equate with the area of movable plate 185.In addition; Flexible member 190 is summed up the thickness a little more than signal link slot 142 with the thickness of movable plate 185; To form a stress buffer device; When making shell on the back 198 pressurizeds, extraneous stress produces the effect that stress is concentrated through element or the joint that flexible member 190 slows down on the circuit board 140, and then reduces the fraction defective generation of backlight module 160 distortion.
Fig. 3 illustrates flat-panel screens 100 constitutional diagrams of Fig. 1, and this figure is the synoptic diagram (shell on the back 198 is combination as yet) after safeguard structure, circuit board, backlight module and display panel group are stood.After 100 groups of flat-panel screens were stood, backlight module 160 is (please with reference to Fig. 1) between display panel 120 and shell on the back 198, and the circuit board 140 of display panel 120 then turns over and places between backlight module 160 and the shell on the back 198 (please with reference to Fig. 1).Safeguard structure 180 covers circuit board 140, and through hole 187 need and signal link slot 142 mutual corresponding fits, to expose signal link slot 142.Flexible member 190 is attached on the wherein one side of movable plate 185, in order to buffering stress; Flexible member 190 also can be attached between movable plate 185 and the backlight module 140, and attaching side does not influence its function.Movable plate 185 has a pull handle 194, and this pull handle 194 and through hole 187 are positioned at two relative edges of movable plate 185, raises movable plate 185 through pulling pull handle 194, can carry out the plug operation of signal link slot 142 and other element.
Fig. 4 illustrates the upright figure of signal connector group.This figure is that movable plate 185 opens and exposes the signal link slot 142 on the circuit board 140, and signal connector 200 is inserted a synoptic diagram of signal link slot 142.In the present embodiment; The terminal corner of movable plate 185 has a plurality of breach 193; When flexible member 190 is attached at movable plate 185 upsides; The glued membrane 192 of flexible member 190 makes glued membrane 192 be able to be pasted on backlight module 160 or the signal connector 200 outside will being revealed in respect to breach 193 places of movable plate 185, fixing movable plate 185 after accomplishing so as to Yu Zuli.Generally, can signal connector 200 be placed on the flexible member 190, also can be placed between movable plate 185 and the backlight module 160, put the stress buffer effectiveness that the position does not influence flexible member carrying out signal connector when inserting operation process.If desire places signal connector 200 between movable plate 185 and the backlight module 160, pulling pull handle 194 then capable of using is raised movable plate 185, and carries out signal connector 200 and the upright operation of the group of signal link slot 142.When signal connector 200 is inserted after operation finishes; Pulling pull handle 194 is covered in movable plate 185 on the signal connector 200; And utilize glued membrane 192 and fixing movable plate 185 positions on the flexible member 190, make flexible member 190 simultaneously as the stress buffer protective device of signal connector 200.When desiring to pull out signal connector 200, need carry out movable plate 185 equally and lift and put operation.
In above-mentioned preferred embodiment, diaphragm 182, movable plate 185 and pull handle 194 are made up of insulating material; Flexible member 190 is materials such as elastic composite material or foam.
Fig. 5 is the safeguard structure figure that illustrates another preferred embodiment of the present invention.In this embodiment, safeguard structure 180 ' comprises a layer insulating 188 and one deck conductive layer 189.In group immediately, insulation course 188 is in order to contacting with circuit board 140, and with as the protective layer that prevents circuit board 140 short circuits, 189 of conductive layers are between insulation course 188 and shell on the back 198.When conductive layer 189 ground connection, make safeguard structure 180 also have the function of electromagnetic protection.
The safeguard structure that the above embodiment of the present invention disclosed utilizes a protective film outwards to spread out and stretches movable plate, and a flexible member is set on the movable plate, can be used for protecting the optical element in the backlight module, particularly backlight module.Diaphragm on the present general circuit plate, the defencive function that improves backlight module also increases its fiduciary level.
Certainly; The present invention also can have other various embodiments; Under the situation that does not deviate from spirit of the present invention and essence thereof; Those of ordinary skill in the art can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection domain of claim of the present invention.
