Abstract
The utility model relates to a transform interface circuit device used for the test of a flat display screen. The device comprises a printed circuit board, a chovr FPC arranged on the board and a porous circuit socket. The utility model improves the trivial procedure in the prior art that the display screen is required to be respectively and directly swapped with each testing equipment, therefore, a lattice screen is not required to be assembled and disassembled repeatedly, the procedure is greatly saved, and the production efficiency is improved. Meanwhile, in the testing process, all row-columns on the display screen are lightened, therefore, the lack row-column display phenomenon can not occur, and the display screen can be ensured to display uniformly after being tested.
Description
Technical field
The utility model relates to a kind of converting interface circuit arrangement that is used for the test of panel display screen.
Background technology
In the prior art, after the processing of finishing display screen on the production line, generally all need by behind this procedure of process test, product just can dispatch from the factory.Common test step comprises two parts, at first is the screen body is carried out high temperature aging, and be conventionally test then to the screen body.
The circuit of high temperature aging of the prior art test, be negative electrode with the dot matrix screen by a lead material short circuit, draw by a lead again; The situation of anode is identical.Because the connection of sort circuit is very unsettled, row occurs lacking in the time of can causing the full screen display of dot matrix screen and show.This situation causes the dot matrix screen through after the high temperature aging, non-uniform phenomenon (lack the place of row when high temperature is seasoned, its brightness meeting is darker than other normal regions) can occur showing.Moreover existing test step is because of the restriction of tested person device, cause operation steps very loaded down with trivial details: at first, display screen need be connected with the testing apparatus of high temperature aging, as shown in Figure 2, after high temperature aging is finished the screen body is taken off, and then display screen reconnected conventionally test equipment, energising is tested, as shown in Figure 3.
Because each piece display screen all needs when entering test so not only to have limited the efficient of producing in batches by manually it is connected, takes off, connect, take off the ground repeatable operation with testing apparatus, increased working hour expense simultaneously, also increased the input of equipment.
The utility model content
The utility model will solve the above-mentioned problem that exists in existing test step, a kind of novel converting interface circuit arrangement is provided, and be used to connect display screen and each testing apparatus.
A kind of converting interface circuit arrangement that is used for panel display screen test, this device comprise a printed circuit board (PCB) and are positioned at switching FPC and porous circuitry socket on this plate.
The quantity of FPC lead-in wire is identical with dot matrix screen lead-in wire.
The utility model can improve display screen in the prior art to be needed respectively and the direct loaded down with trivial details operation of plug of each testing apparatus, adopt converting interface circuit arrangement of the present utility model, as long as with the porous circuitry socket conversion different testing apparatuss of pegging graft, just can realize the test of conventional dot matrix screen, can carry out the high temperature aging test again, need not load and unload the dot matrix screen more repeatedly, save operation greatly, improve production efficiency.Simultaneously because the lead-in wire of the FPC on the converting interface circuit arrangement that adopts be with the lead-in wire of dot matrix screen one to one, in test process, ranks on the display screen are all lighted, and just can not occur lacking the phenomenon that row shows, can guarantee can show evenly after display screen is through test.

Embodiment:
Description of reference numerals:
1 is display screen; 2 is the FPC circuit; 3 is printed circuit board (PCB); 4 is the porous power source socket; 5 is frock clamp; 6 is the circuit interface of normal temperature testing apparatus; 7 is the circuit interface of the seasoned testing apparatus of high temperature; 61 are the circuit lead for connection normal temperature testing apparatus in the prior art; 81 is the circuit lead that connects the seasoned testing apparatus of high temperature in the prior art; 82 is the circuit lead that connects the seasoned testing apparatus of high temperature in the utility model.
When the utility model is tested display screen, at first use frock clamp that display screen is connected with the converting interface circuit arrangement, as shown in Figure 6, wherein 5 is frock clamp.
Lead-in wire on the display screen links to each other with the lead-in wire of FPC, and as Fig. 4, shown in Figure 5, wherein COM1～COM63 is a dot matrix screen negative electrode odd-numbered line, and COM0～COM62 is a dot matrix screen negative electrode even number line, and SEG1～SEG131 is the anode column of dot matrix screen.Because the FPC on the converting interface circuit arrangement goes between be and lead-in wire one correspondence of dot matrix screen, in test process, the ranks on the display screen are all lighted, and the phenomenon of row demonstration just can not occur lacking, can guarantee can show evenly after display screen is through test.
Then, the circuit interface of normal temperature testing apparatus is connected with porous socket on the converting interface circuit arrangement, display screen is carried out the normal temperature test.The circuit plug of normal temperature testing apparatus joins with porous socket as shown in Figure 6.
After finishing the normal temperature test, again the circuit interface of the porous socket on the converting interface circuit arrangement with the seasoned testing apparatus of high temperature is connected, display screen is carried out the seasoned test of high temperature.Because picking out the lead-in wire that comes, the plug during the high temperature aging test needs short circuit, be 64 naked input same signals that are connected together of lead-in wire of COM0～COM63,132 naked being connected together of lead-in wire of same SEG1～SEG131, the synoptic diagram that its plug is connected with porous socket as shown in Figure 7.
By above-mentioned embodiment, use converting interface circuit arrangement of the present utility model, the operation when having saved the display screen test has greatly improved production efficiency, also can not produce the infringement to the display screen body simultaneously.
Although describe the present invention in conjunction with the preferred embodiments; but the present invention is not limited to the foregoing description and accompanying drawing; be to be understood that; under the guiding of the present invention's design; without departing from the spirit and scope of the present invention; a few modifications that those skilled in the art only carry out and retouching are protection scope of the present invention and cover
