Description

A kind of LCD module short circuit test adapter
Technical field
The utility model relates to LCM test device field, refers to a kind of LCD module short circuit test adapter especially.
Background technology
In existing LCD module short circuit test, when being connected providing the control chip of test resource with tested LCD MODULE, because the arrangement mode of the output port of control chip and the arrangement mode of each pin of tested LCD MODULE are not quite similar, need operating personnel for different tested LCD MODULE, connected by the wiring of complexity, the pin of the output port of control chip with tested LCD MODULE is connected; Meanwhile, often test a LCD MODULE, all need to repeat said process, this has had a strong impact on the work efficiency of whole test.
Utility model content
In view of this, the purpose of this utility model is to propose the LCD module short circuit test adapter that a kind of structure is simple, testing efficiency is higher.
Based on a kind of LCD module short circuit test adapter that above-mentioned purpose the utility model provides, comprising: general loading plate and special card extender; There is provided the control chip of test resource to be fixed on described general loading plate, described special card extender is dismountable is connected to described general loading plate; Described special card extender is provided with PCB layout to be connected first interface group and the second interface group, described first interface group is connected with the output terminal of control chip, described second interface group is used for being connected with tested LCD MODULE, and the arrangement of the interface of described second interface group is arranged identical with the pin of tested LCD MODULE.
Optionally, the output terminal of control chip is connected with the first interface group of described special card extender by PCB layout or winding displacement.
As can be seen from above, the LCD module short circuit test adapter that the utility model provides, control chip and special card extender is fixed by general loading plate, the LCD MODULE of different model uses the special card extender corresponding with it, realize simple fast connection, avoid in existing method of testing, the mode of manual line, improves work efficiency.
Accompanying drawing explanation
Fig. 1 is the LCD module short circuit test adapter schematic diagram of the utility model embodiment;
Fig. 2 is the control chip output terminal schematic diagram used in the utility model embodiment;
Fig. 3 is the special card extender schematic diagram of the utility model embodiment.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with specific embodiment, and with reference to accompanying drawing, the utility model is further described.
With reference to figure 1, it is the LCD module short circuit test adapter schematic diagram of the utility model embodiment.
The utility model embodiment provides a kind of LCD module short circuit test adapter, comprising: general loading plate 1 and special card extender 2; There is provided the control chip 3 of test resource to be fixed on described general loading plate 1, described special card extender 2 is dismountable is connected to described general loading plate 1; Described special card extender is provided with PCB layout to be connected first interface group and the second interface group, described first interface group is connected with the output terminal of control chip 3, described second interface group is used for being connected with tested LCD MODULE 4, and the arrangement of the interface of described second interface group is arranged identical with the pin of tested LCD MODULE 4.
General loading plate 1 is mainly used in the position of fixing control chip 3 and special card extender 2, makes the compact conformation of whole device.Concrete, special card extender 2 is one piece of pcb board, is provided with first interface group and the second interface group, and wherein, first interface group is used for being connected with control chip 3, and the second interface group is used for being connected with tested LCD MODULE 4; First interface group is connected by PCB layout with before the second interface group.By the PCB layout on special card extender 2, interface in interface in first interface group and the second interface group is connected one to one, output terminal by control chip 3 is connected to the different pins of tested LCD MODULE 4 accordingly, realize the test resource of control chip 3 being applied in tested LCD MODULE 4, to carry out the short-circuit test to tested LCD MODULE 4.
Referring to figs. 2 and 3, be respectively the special card extender schematic diagram of control chip output terminal schematic diagram and the utility model embodiment used in the utility model embodiment.
Special card extender 2 is corresponding with tested LCD MODULE 4, namely when the LCD MODULE of test different model, specification, chooses different special card extenders 2.For the tested LCD MODULE 4 of different model, the arrangement mode of the pin of its difference in functionality is not quite similar, but the output end position of control chip 3 is changeless.Then by the special card extender 2 of the utility model embodiment, when testing the LCD MODULE of different model, select the special card extender 2 supporting with it.Between different special card extenders 2, its first interface group part is identical, namely all can be connected with the output terminal of control chip 3; Different parts is the arrangement mode of interface in PCB layout on special card extender 2 and the second interface group.On distinct interface in the second interface group each output terminal of control chip 3 being connected to corresponding thereto by the PCB layout on special card extender 2, during test, the test resource namely achieving control chip 3 that only needs tested LCD MODULE 4 to be directly connected with the second interface group of special card extender 2 applies tested LCD MODULE 4.
As preferably, general loading plate 1 is one piece of pcb board, and by the wiring on it, the output terminal of control chip 3 is connected with the first interface group of special card extender 2; In addition, also by winding displacement, the first interface group of the output terminal of control chip 3 with special card extender 2 can be connected.
For the utility model, by changing the control chip 3 that can provide different test resource, test adapter of the present utility model can be made further for testing the other technologies parameter of LCD MODULE.
Those of ordinary skill in the field are to be understood that: the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle; any amendment of making, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
