According to the direct and rapid testing tool, the problem of testing mass liquid crystal screens before leaving a factory is solved, a testing result is visual, and judgment can be rapidly carried out.
Description
Technical field
The utility model relates to the LCDs field, relates in particular to the test of the operation interface of the button on the liquid crystal display module, USB socket, VGA socket and puts tool.
Background technology
LCD is widely used in various electronic equipments and shows, such as the man-machine dialog interface of GPS automobile travel recorder, this LCDs adopts the production and processing mode of COB; Have the advantages that temperature range is wide, reliability is high, the antivibration ability is good; Usually have usb socket, video interface socket and operation at the LCDs periphery, be connected to customer interface through the interface line FPC on the liquid crystal display module again, accomplish control external unit; And the interface line FPC on the liquid crystal display module is the 20PIN pin; The FPC FPC winding displacement that the more spacing of pin is closeer adopts artificial welding to be easy to generate the situation of open circuit, short circuit, rosin joint, be to FPC welding back test; If complete machine carries out the operation interface test; Test speed can be very slow, influences shipment in enormous quantities, needs a kind of quick, simple test to put tool and satisfy the demand of producing.
Summary of the invention
The utility model has proposed a kind of test quick, the simple test LCDs to above problem and has put tool.
The technical scheme of the utility model is: a kind of lcd panel test is put tool; Comprise testing and put the tool body; On body, be used to the LED lamp that shows test results; It is characterized in that, put the liquid crystal/button that is provided with on the tool body in test and light card extender, light clinching that 20PIN FPC connecting line on the locking liquid crystal module is arranged on the card extender 2 and the press strip of being with adhesive tape at liquid crystal/button; Put on the tool in test and to also have and female plug of USB that the public headstock of liquid crystal display USB is pegged graft and the female plug of VGA of pegging graft with the public headstock of VGA on the liquid crystal module.
The beneficial effect of the utility model is: tool is put in a kind of directly and efficiently test, solve the test problem of liquid crystal display in enormous quantities before dispatching from the factory, and test result is directly perceived, can judge fast.
Description of drawings
Fig. 1 is the utility model one example structure synoptic diagram.
Wherein: 1, the tool body is put in test; 2, liquid crystal/button is lighted card extender; 3, clinching; 4, press strip; 5, the female plug of USB; 6, the female plug of VGA.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.
Embodiment 1:
The technical scheme of the utility model is: a kind of lcd panel test is put tool; Comprise testing and put tool body 1; Put the LED lamp that is used to show test results on the tool body 1 in test; It is characterized in that, put the liquid crystal/button that is provided with on the tool body 1 in test and light card extender 2, at the press strip 4 of clinching 3 that 20PIN FPC connecting line on the locking liquid crystal module is arranged on liquid crystal/button card extender 2 and band adhesive tape; Put on the tool in test and to also have and female plug 5 of USB that the public headstock of liquid crystal display USB is pegged graft and the female plug 6 of VGA of pegging graft with the public headstock of VGA on the liquid crystal module.
At first the liquid crystal module of testing being placed on test puts on the tool body 1; The 20PIN FPC connecting line of liquid crystal display module is aimed at liquid crystal/button light card extender 2; Depress clinching 3; Pin the press strip 4 of band adhesive tape, the 20PIN FPC connecting line on the liquid crystal module is connected with the built-in control panel of driving liquid crystal, and light card extender 2 with liquid crystal/button and link to each other.
Also through pressing press strip 4, connected the 20PIN FPC on the liquid crystal module and transferred being connected of winding displacement simultaneously, accomplished the liquid crystal display module and light being connected of card extender with the double LED of the USB/VGA on the testing making apparatus with USB/VGA.
The tester is inserted into the female plug 5 of USB of band line on the testing making apparatus in the public headstock of USB on the liquid crystal module then, and the female plug 6 of VGA is inserted into the public headstock of VGA on the liquid crystal module.
The above has accomplished the connection of the liquid crystal display module testing hardware of test.
Again the testing jig power switch is opened, let drive the built-in control panel energising of liquid crystal work,, differentiate the fine or not situation of liquid crystal display assembling, accomplish the first step of LCDs test through the LCDs content displayed.
The tester presses four buttons on the liquid crystal module one by one, and the button LED of testing making apparatus lighted lantern festival and lighted one by one this moment, if do not work, is the open circuit performance, accomplishes the test of first operation interface.
Tester fluctuation arrange up and down LED voltage transitions waved switch each once, corresponding USB/VGA go up row's LED lamp and USB/VGA down row LED lantern festival in turn quilt lighted.
If there is the LED lamp not work, be the liquid crystal display module open circuit performance of test.
If bank light is bright up and down simultaneously for the LED lamp, then be the liquid crystal display module short circuit performance of test.
The liquid crystal display module that below all can be test is connected open circuit with the wiring of three operation interfaces, short circuit, the defective products of rosin joint.
Claims (1)
1. a lcd panel test is put tool; Comprise that test puts the tool body, on body, be used to the LED lamp that shows test results, it is characterized in that; Put the liquid crystal/button that is provided with on the tool body in test and light card extender; Light the clinching that 20PIN FPC connecting line on the locking liquid crystal module is arranged on the card extender and the press strip of band adhesive tape at liquid crystal/button, put on the tool in test and also have and female plug of USB that the public headstock of liquid crystal display USB is pegged graft and the female plug of VGA of pegging graft with the public headstock of VGA on the liquid crystal module.
