Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment one
Figure 1 shows that and comprise glass substrate end (Chip on Glass) 1, flexible printed circuit board end (Film on Glass) 2, test group 3, and off normal test group 4 by the one display module that the utility model embodiment one provides.Wherein, test group 3 comprises test board 3A and bus 3B corresponding thereto, and test board 3A takes the shape of the letter U, and comprise two test-strips 3a and connecting portion 3b, 3a and 3b is integrally formed.Off normal test group 4 comprises off normal test board 4A and bus 4B corresponding thereto, off normal test board 4A takes the shape of the letter U, comprise two off normal test-strips 4a and connecting portion 4b, 4a and 4b is integrally formed, the width of off normal test-strips 4a is less than the width of off normal bus 4B corresponding thereto, and the width of off normal bus 4B is equal with the width of bus 3B.The test-strips of the bus of flexible printed circuit board end with glass substrate end connected, the horizontal contact section of each test-strips bus is corresponding thereto divided into contact length.The Maximum Contact length of off normal test group 4, length when namely off normal bus 4B contacts completely with off normal test-strips 4a, is less than the Maximum Contact length of test group 3, length when namely bus 3B contacts completely with test-strips 3a.The material of test board 3A and off normal test board 4A is the stacking material of aluminium, molybdenum and molybdenum, aluminium, molybdenum, and the material of bus 3B and off normal bus 4B is aluminium.
Alternatively, the material of test board 3A and off normal test board 4A is the stepped construction of the stacking material of aluminium and molybdenum or aluminium, molybdenum, aluminium, or can be separately tin indium oxide (ITO) material, does not limit, as long as all material is conductive material at this.
Alternatively, test board 3A and off normal test board 4A can be non-integral shaped structure, and namely test-strips 3a and bus 3B can be splicing construction, and equally, off normal test-strips 4a and bus 4B can be splicing construction.
Alternatively, the number of test-strips 3a and/or off normal test-strips 4a can be greater than 2.
Alternatively, the number of off normal test group 4 can be multiple, does not limit at this, is more than or equal to 1.
Alternatively, in off normal test group 4, the width of bus 4B can be less than the width of test-strips 4a, does not limit width at this, as long as make the Maximum Contact length of off normal test group 4 be less than the maximum length of test group 3.
Thus, when testing, in conjunction with test platform, measure the resistance of binding (bonding) series circuit afterwards.Suppose to produce line patient binding (bonding) off normal value for (bonding) off normal 50% can be bound, so the width design of off normal test-strips 4a can be become 50% of the width of off normal bus 4B corresponding thereto, like this, the Maximum Contact length of off normal test group 4 is less than the Maximum Contact length of test group 3, when off normal occurs in binding (bonding), according to resistance sizes, binding (bonding) off normal situation can be judged.When binding (bonding) off normal 50%, whole string test circuit is open-circuit condition, thus learns that the off normal of binding (bonding) has exceeded product line tolerance value, can make prevention in advance.
Simultaneously, this display modular structure is simple to operate, the width of off normal bus or off normal test-strips in off normal test group is only changed when designing, binding (bonding) situation can be detected on the whole from binding (bonding) during test, the product that effective interception binding (bonding) is not strong, and improve the efficiency of producing line binding (bonding) and detecting.
Embodiment two
As shown in Figure 2, the one provided for the utility model embodiment two shows module.Repeat no more with previous embodiment same section in the present embodiment, only describe different piece.Different from previous embodiment, in the present embodiment, the width of the width off normal bus 4B corresponding thereto of off normal test-strips 4a is equal, and the width of off normal test-strips 4a and off normal bus 4B is less than the width of test-strips 3a and bus 3B.
Thus, when testing, in conjunction with test platform, measure the resistance of binding (bonding) series circuit afterwards.Suppose to produce line patient binding (bonding) off normal value for (bonding) off normal 50% can be bound, so off normal test-strips 4a can be become 50% of test-strips 3a and bus 3B width with the width design of off normal bus 4B, like this, the Maximum Contact length of off normal test group 4 is less than the Maximum Contact length of test group 3, when off normal occurs in binding (bonding), according to resistance sizes, binding (bonding) off normal situation can be judged.When binding (bonding) off normal 50%, whole string test circuit is open-circuit condition, thus learns that the off normal of binding (bonding) has exceeded product line tolerance value, can make prevention in advance.
Simultaneously, this display modular structure is simple to operate, the width that simultaneously can regulate off normal bus and off normal test-strips in off normal test group is only changed when designing, improve the accuracy of test, binding (bonding) situation can be detected on the whole from binding (bonding) during test, the product that effective interception binding (bonding) is not strong, and improve the efficiency of producing line binding (bonding) and detecting.
Embodiment three
As shown in Figure 3, the one provided for the utility model embodiment three shows module.Repeat no more with previous embodiment same section in the present embodiment, only describe different piece.Different from previous embodiment, the width of the width off normal bus 4B corresponding thereto of off normal test-strips 4a is equal, but the spacing of two off normal test-strips 4a is greater than the spacing of two off normal bus 4B.
Alternatively, when the width of the width off normal bus 4B corresponding thereto of off normal test-strips 4a is equal, the spacing that can arrange two off normal test-strips 4a is less than the spacing of two off normal bus 4B, do not limit at this, as long as make the Maximum Contact length of off normal test group 4 be greater than the Maximum Contact length of test group 3.
Thus, when testing, in conjunction with test platform, measure the resistance of binding (bonding) series circuit afterwards.Suppose to produce line patient binding (bonding) off normal value for (bonding) off normal 50% can be bound, when the width of the width off normal bus 4B corresponding thereto of off normal test-strips 4a is equal, the spacing arranging two off normal test-strips 4a is less than/is greater than the spacing of two off normal bus 4B, the Maximum Contact length of off normal test-strips 4a and off normal bus 4B is made to be 50% of test-strips 3a and bus 3B, when off normal occurs in binding (bonding), according to resistance sizes, binding (bonding) off normal situation can be judged.When binding (bonding) off normal 50%, whole string test circuit is open-circuit condition, thus learns that the off normal of binding (bonding) has exceeded product line tolerance value, can make prevention in advance.
Simultaneously, this display modular structure is owing to adding the spacing of unit area build-in test bar or bus, the quantity of the test-strips therefore in unit area or bus reduces, reduce cost of manufacture, and binding (bonding) situation can be detected on the whole from binding (bonding) when testing, (bonding) not strong product is tied up in effective interception, and improves the efficiency of producing line binding (bonding) and detecting.
Embodiment four
As shown in Figure 4, the one provided for the utility model embodiment four shows module.Repeat no more with previous embodiment same section in the present embodiment, only describe different piece.Different from previous embodiment, the width of off normal test-strips 4a is less than the width of its relative off normal bus 4B, and the spacing of two off normal test-strips 4a is greater than the spacing of two off normal bus 4B.
Alternatively, the width of off normal test-strips 4a can be less than the width of its relative off normal bus 4B, and the spacing of two off normal test-strips 4a is less than the spacing of two off normal bus 4B.
Alternatively, the width of off normal test-strips 4a can be greater than the width of its relative off normal bus 4B, and the spacing of two off normal test-strips 4a is less than the spacing of two off normal bus 4B.
Alternatively, the width of off normal test-strips 4a can be greater than the width of its relative off normal bus 4B, and the spacing of two off normal test-strips 4a is greater than the spacing of two off normal bus 4B.
What need again to illustrate at this is, here the width of off normal test-strips 4a and off normal bus 4B and spacing are not limited, as long as ensure the Maximum Contact length of off normal test-strips 4a and off normal bus 4B, namely horizontal length when off normal test-strips 4a and off normal bus 4B contacts completely is greater than the Maximum Contact length of test-strips 3a and bus 3B, horizontal length when namely test-strips 3a contacts completely with bus 3B.
Thus, when testing, in conjunction with test platform, measure the resistance of binding (bonding) series circuit afterwards.Suppose to produce line patient binding (bonding) off normal value for (bonding) off normal 50% can be bound, then by the width of adjustment off normal test-strips 4a or off normal bus 4B, and the spacing making spacing two off normal bus 4B corresponding thereto of two off normal test-strips 4a is not etc., the Maximum Contact length of off normal test-strips 4a and off normal bus 4B is made to be 50% of test-strips 3a and bus 3B, when off normal occurs in binding (bonding), according to resistance sizes, binding (bonding) off normal situation can be judged.When binding (bonding) off normal 50%, whole string test circuit is open-circuit condition, thus learns that the off normal of binding (bonding) has exceeded product line tolerance value, can make prevention in advance.
Simultaneously, this display modular structure adds the dirigibility of module design, the off normal test group of the different situations design different display module needs of module can be shown according to difference, and binding (bonding) situation can be detected on the whole from binding (bonding) when testing, (bonding) not strong product is tied up in effective interception, and improves the efficiency of producing line binding (bonding) and detecting.
Finally it should be noted that, those skilled in the art can carry out various change and modification to the utility model and not depart from spirit and scope of the present utility model.Like this, if these amendments of the present utility model and modification belong within the scope of the utility model claim and equivalent technologies thereof, then the utility model is also intended to comprise these change and modification.
