Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A binding detection apparatus of a display apparatus according to an embodiment of the present invention is described below with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of a binding detection apparatus of a display apparatus according to an embodiment of the present invention. As shown in fig. 1 to 4, the display device includes a connection module 101, the connection module 101 includes a first connection member 111 and a second connection member 112 matching with the first connection member 111, the connection module 101 forms a plurality of binding units 1011 when the first connection member 111 is bound with the second connection member 112, and each binding unit is electrically conductive.
The binding detection device comprises a first detection point A, a second detection point B and a detection module 201, wherein the detection module 201 is configured to sequentially connect any N binding units 1011 in the plurality of binding units 1011 in series, connect the first ends of the N binding units 1011 connected in series to the first detection point A, connect the second ends of the N binding units 1011 connected in series to the second detection point B, and N is an integer greater than 1; the binding state of the first connecting piece 111 and the second connecting piece 112 is determined by measuring the resistance between the first detecting point a and the second detecting point B.
It can be understood that the detecting module 201 can connect N binding units 1011 in series and in series between the first detecting point a and the second detecting point B, where N is greater than 1 and less than or equal to the total number of the binding units 1011, that is, the detecting module 201 can connect some or all of the binding units 1011 in series, so that the resistance between the first detecting point a and the second detecting point B is the resistance after the partial binding units 1011 or all binding units 1011 are connected in series, when at least one of the N binding units 1011 connected in series has a binding abnormality, the resistance of the N binding units 1011 is abnormal, that is, the resistance between the first detecting point a and the second detecting point B is abnormal, when the N binding units 1011 connected in series are normally bound, the resistance of the N binding units 1011 is normal, that is, the resistance between the first detecting point a and the second detecting point B is normal, therefore, the binding effect can be timely and accurately confirmed by testing the resistance values of the N binding units connected in series, and the problem that the binding state of part of binding points cannot be monitored due to the fact that only one binding resistance value can be measured is solved.
Further, when the resistance value between the first detection point a and the second detection point B is greater than the preset resistance value, it is determined that the binding state between the first connecting member 111 and the second connecting member 112 is abnormal.
It should be noted that the preset resistance value may be determined in combination with an actual process, and may be, for example, 20 Ω.
That is, when at least one of the N binding units 1011 connected in series has a binding abnormality, the resistance values of the N binding units 1011 exceed a preset resistance value, that is, the resistance value between the first detection point a and the second detection point B is greater than the preset resistance value, and thus, by detecting that the resistance value between the first detection point a and the second detection point B is greater than the preset resistance value, it can be determined that the binding state has an abnormality; when the N binding units 1011 connected in series are normally bound, the resistance values of the N binding units 1011 are less than or equal to the preset resistance value, that is, the resistance value between the first detection point a and the second detection point B is less than or equal to the preset resistance value, and therefore, by detecting that the resistance value between the first detection point a and the second detection point B is less than or equal to the preset resistance value, it can be determined that the binding state is not abnormal.
According to an embodiment of the present invention, as shown in fig. 2-3, the detection module 201 includes a first detection component 211 and a second detection component 212, the first detection component 211 includes a 1 st detection end J1 to an nth detection end JN, the second detection component 212 includes a (N +1) th detection end J (N +1) to a 2 nth detection end J (2N), N is an odd number, wherein the 1 st detection end J1 is connected to the first detection point a, and the 1 st detection end J1 is further connected to the first ends of the 1 st binding units of the N binding units, the 2 nd detection end J2 to the nth detection end JN are respectively connected to the first ends of the 2 nd binding units to the nth binding units of the N binding units, and each two detection ends of the 2 nd detection end J2 to the nth detection end JN are connected in series to connect the first ends of the corresponding two binding units in series; the (N +1) th detection end J (N +1) is connected with the second detection point B, the (N +1) th detection end J (N +1) is connected with the second end of the N-th binding unit in the N-th binding units, the (N +2) th detection end J (N +2) to the 2N-th detection end J (2N) are correspondingly connected with the second ends of the 1-th binding unit to the (N-1) th binding unit in the N-th binding units respectively, and every two detection ends in the (N +2) th detection end J (N +2) to the 2N-th detection end J (2N) are connected in series to connect the second ends of the corresponding two binding units in series.
For example, as shown in fig. 2-3, in the first detecting element 211, the 1 st detecting terminal J1 to the nth detecting terminal JN may be sequentially arranged from left to right, and in the second detecting element 212, the (N +1) th detecting terminal J (N +1) to the 2 nth detecting terminal J (2N) may be sequentially arranged from right to left. And, the 1 st to nth binding units may also be sequentially arranged from left to right. It is understood that the N binding units may be any N binding units of the plurality of binding units, including but not limited to, the 1 st binding unit to the nth binding unit may be N consecutive binding units of the plurality of binding units, for example, as shown in fig. 2, may be N consecutive binding units on the left side of the connection module 101; alternatively, the 1 st to nth binding units may be N binding units spaced by a plurality of binding units, for example, as shown in fig. 3, N binding units are selected from every 1 binding unit of the plurality of binding units.
Therefore, the N binding units are connected between the first detection point A and the second detection point B in series, and the binding state can be judged through the resistance value between the first detection point A and the second detection point B.
It is understood that every two adjacent detection terminals among the 2 nd detection terminal J2 through the nth detection terminal JN may be connected in series, and every two adjacent detection terminals among the (N +2) th detection terminal J (N +2) through the 2 nth detection terminal J (2N) may be connected in series. That is, the 1 st detecting terminal J1 and the detecting terminals other than the (N +1) th detecting terminal J (N +1) may be connected two by two. For example, as shown in FIGS. 2-3, the 2 nd detection terminal J2 can be connected to the 3 rd detection terminal J3, the 4 th detection terminal J4 can be connected to the 5 th detection terminal J5, the 6 th detection terminal J6 can be connected to the 7 th detection terminal J7, and so on, until the (N-1) th detection terminal J (N-1) can be connected to the Nth detection terminal JN. Similarly, the (N +2) th detecting terminal J (N +2) may be connected to the (N +3) th detecting terminal J (N +3), the (N +4) th detecting terminal J (N +4) may be connected to the (N +5) th detecting terminal J (N +5), the (N +6) th detecting terminal J (N +6) may be connected to the (N +7) th detecting terminal J (N +7), and so on until the (2N-1) th detecting terminal J (2N-1) may be connected to the 2N-th detecting terminal J (2N).
The detection principle of the detection module 201 is described in detail below with reference to the embodiment of fig. 2. As shown in fig. 2, the 1 st detection end J1 to the nth detection end JN may sequentially correspond to N consecutive binding units on the left side of the connection module 101, that is, the 1 st detection end J1 to the nth detection end JN respectively correspond to N binding units at positions 1 to N in fig. 2; moreover, the (N +1) th detection end J (N +1) to the 2N th detection end J (2N) sequentially correspond to N consecutive binding units on the left side of the connection module 101, that is, the 2N detection end J (2N) to the (N +1) th detection end J (N +1) respectively correspond to N binding units at positions 1 to N in fig. 2.
Furthermore, the first detection point a can be connected to the first end of the 1 st binding unit (the binding unit at position 1 in fig. 2) through the 1 st detection end J1, the second end of the 1 st binding unit is connected to the 2N-th detection end J (2N), the 2N-th detection end J (2N) is connected to the (2N-1) th detection end J (2N-1), and the (2N-1) th detection end J (2N-1) is connected to the second end of the 2 nd binding unit (the binding unit at position 2 in fig. 2), so that the 1 st binding unit and the 2 nd binding unit are connected in series. Also, the first terminal of the 2 nd binding unit is connected to the 2 nd sensing terminal J2, the 2 nd sensing terminal J2 is connected to the 3 rd sensing terminal J3, and the 3 rd sensing terminal J3 is connected to the first terminal of the 3 rd binding unit (the binding unit at position 3 in FIG. 2), so that the 2 nd binding unit and the 3 rd binding unit are connected in series. By analogy, through the foregoing connection manner, consecutive N binding units may be connected in series, and the N binding units may be connected in series with reference to the dotted line in fig. 2.
Therefore, N continuous binding units in the plurality of binding units can be connected in series, and the resistance value between the first detection point A and the second detection point B is the sum of the resistance values of the N binding units, so that when at least one binding unit is not bound, such as broken circuit, the resistance value of at least one binding unit is larger, the resistance value between the first detection point A and the second detection point B is detected to exceed the preset resistance value, and the binding state can be judged to be abnormal according to the resistance value between the first detection point A and the second detection point B.
In addition, the detection principle of the detection module 201 will be described in detail below with reference to the embodiment of fig. 3. As shown in fig. 3, the 1 st detection end J1 to the nth detection end JN may sequentially correspond to N binding units at intervals in the connection module 101, that is, the 1 st detection end J1 to the nth detection end JN respectively correspond to N binding units at N positions, such as position 3, position 5, position 7, and position 9, in fig. 2; moreover, the (N +1) th detection end J (N +1) to the 2N th detection end J (2N) sequentially correspond to N binding units at intervals in the connection module 101, that is, the 2N detection end J (2N) to the (N +1) th detection end J (N +1) respectively correspond to N binding units at N positions, such as position 3, position 5, position 7, and position 9, in fig. 2.
Furthermore, the first detection point a can be connected to the first end of the 1 st binding unit (the binding unit at position 2 in fig. 2) through the 1 st detection end J1, the second end of the 1 st binding unit is connected to the 2N-th detection end J (2N), the 2N-th detection end J (2N) is connected to the (2N-1) th detection end J (2N-1), and the (2N-1) th detection end J (2N-1) is connected to the second end of the 2 nd binding unit (the binding unit at position 5 in fig. 2), so that the 1 st binding unit and the 2 nd binding unit are connected in series. Also, the first terminal of the 2 nd binding unit is connected to the 2 nd sensing terminal J2, the 2 nd sensing terminal J2 is connected to the 3 rd sensing terminal J3, and the 3 rd sensing terminal J3 is connected to the first terminal of the 3 rd binding unit (the binding unit at position 7 in FIG. 2), so that the 2 nd binding unit and the 3 rd binding unit are connected in series. By analogy, through the aforementioned connection manner, N binding units at intervals can be connected in series, and the N binding units can be connected in series with reference to the dotted line in fig. 3.
Therefore, N binding units at intervals in the plurality of binding units can be connected in series, and the resistance value between the first detection point A and the second detection point B is the sum of the resistance values of the N binding units, so that when at least one binding unit is not bound, such as broken circuit, the resistance value of at least one binding unit is larger, the resistance value between the first detection point A and the second detection point B is detected to exceed the preset resistance value, and the binding state can be judged to be abnormal according to the resistance value between the first detection point A and the second detection point B.
According to an embodiment of the present invention, as shown in fig. 2 and 4, each of the 1 st sensing terminal J1 to the 2N nd sensing terminal J (2N) may be defined by a conductive sheet corresponding to one binding unit, and two sensing terminals connected in series are connected by a wire L. That is, the N binding units may be connected in series in a manner that the conductive sheets correspond to the binding units 1011 one to one and the conductive sheets are connected by wires. Specifically, as shown in fig. 2, taking the 2 nd inspection J2 and the 3 rd inspection terminal J3 as an example, one conductive sheet may be used as the 2 nd inspection terminal J2, the one conductive sheet corresponds to one binding unit 1011, that is, the binding unit at position 2 in fig. 2, another conductive sheet may correspond to the 3 rd inspection terminal J3, the another conductive sheet corresponds to another binding unit 1011, that is, the binding unit at position 3 in fig. 2, and the two conductive sheets are connected by a wire L, so as to connect two binding units corresponding to the two conductive sheets.
Therefore, more than two binding units can be connected in series between the first detection point A and the second detection point B in any mode, and the method is easy to implement and low in cost.
According to another embodiment of the present invention, as shown in fig. 3, the 1 st detection terminal J1 to the 2N th detection terminal J (2N) are defined by conductive sheets covering at least two binding units, wherein the two detection terminals connected in series respectively correspond to two ends of the conductive sheets. That is, N binding units may be connected in series in such a manner that one conductive sheet corresponds to a plurality of binding units 1011. Specifically, as shown in fig. 3, taking the 2 nd inspection J2 and the 3 rd inspection terminal J3 as examples, one conductive sheet may correspond to 3 binding units, one end of the conductive sheet may be taken as the 2 nd inspection terminal J2, and the other end of the conductive sheet may correspond to the 3 rd inspection terminal J3, one end of the conductive sheet corresponds to one binding unit 1011, that is, the binding unit at the position 3 in fig. 3, and the other end of the conductive sheet corresponds to the other binding unit 1011, that is, the binding unit at the position 5 in fig. 2, and then the two corresponding binding units are connected through the conductive sheet.
Therefore, the conducting plate with a large area is adopted, effective connection with the binding unit can be ensured, detection errors caused by poor contact between the conducting plate and the binding unit are avoided, and the method is easy to realize and low in cost.

For example, as shown in fig. 4, in the first detecting element 211, the 1 st detecting terminal J1 to the nth detecting terminal JN may be sequentially arranged from left to right, and in the second detecting element 212, the (N +1) th detecting terminal J (N +1) to the 2 nth detecting terminal J (2N) may be sequentially arranged from right to left. And, the 1 st to nth binding units may also be sequentially arranged from left to right. It is understood that the N binding units may be any N binding units of the plurality of binding units, including but not limited to, the 1 st binding unit to the nth binding unit may be N consecutive binding units of the plurality of binding units, for example, as shown in fig. 4, may be N consecutive binding units on the left side of the connection module 101; alternatively, the 1 st to nth binding units may be N binding units spaced by a plurality of binding units, for example, N binding units are selected from every 1 st binding unit in the plurality of binding units.
Therefore, the N binding units are connected between the first detection point A and the second detection point B in series, and the binding state can be judged through the resistance value between the first detection point A and the second detection point B.
It is understood that every two adjacent ones of the 2 nd to (N-1) th detection terminals J2 to J (N-1) may be connected in series, and every two adjacent ones of the (N +1) th to 2N detection terminals J (N +1) to J (2N) may be connected in series. That is, the detection terminals other than the 1 st detection terminal J1 and the N-th detection terminal JN may be connected two by two. For example, as shown in FIG. 4, the 2 nd detection port J2 can be connected to the 3 rd detection port J3, the 4 th detection port J4 can be connected to the 5 th detection port J5, the 6 th detection port J6 can be connected to the 7 th detection port J7, and so on, until the (N-2) th detection port J (N-2) is connected to the (N-1) th detection port J (N-1). Similarly, the (N +1) th detecting terminal J (N +1) may be connected to the (N +2) th detecting terminal J (N +2), the (N +3) th detecting terminal J (N +3) may be connected to the (N +4) th detecting terminal J (N +4), the (N +5) th detecting terminal J (N +5) may be connected to the (N +6) th detecting terminal J (N +6), and so on until the (2N-1) th detecting terminal J (2N-1) may be connected to the 2N-th detecting terminal J (2N).
The detection principle of the detection module 201 is described in detail below with reference to the embodiment of fig. 4. As shown in fig. 4, the 1 st detection end J1 to the nth detection end JN may sequentially correspond to N consecutive binding units on the left side of the connection module 101, that is, the 1 st detection end J1 to the nth detection end JN respectively correspond to N binding units at positions 1 to N in fig. 4; moreover, the (N +1) th detection end J (N +1) to the 2N th detection end J (2N) sequentially correspond to N consecutive binding units on the left side of the connection module 101, that is, the 2N detection end J (2N) to the (N +1) th detection end J (N +1) respectively correspond to N binding units at positions 1 to N in fig. 2.
Furthermore, the first detection point a can be connected to the first end of the 1 st binding unit (the binding unit at position 1 in fig. 4) through the 1 st detection end J1, the second end of the 1 st binding unit is connected to the 2N-th detection end J (2N), the 2N-th detection end J (2N) is connected to the (2N-1) th detection end J (2N-1), and the (2N-1) th detection end J (2N-1) is connected to the second end of the 2 nd binding unit (the binding unit at position 2 in fig. 4), so that the 1 st binding unit and the 2 nd binding unit are connected in series. Also, the first terminal of the 2 nd binding unit is connected to the 2 nd sensing terminal J2, the 2 nd sensing terminal J2 is connected to the 3 rd sensing terminal J3, and the 3 rd sensing terminal J3 is connected to the first terminal of the 3 rd binding unit (the binding unit at position 3 in FIG. 4), so that the 2 nd binding unit and the 3 rd binding unit are connected in series. By analogy, through the foregoing connection manner, consecutive N binding units may be connected in series, and the N binding units may be connected in series with reference to the dotted line in fig. 4.
Therefore, N continuous binding units in the plurality of binding units can be connected in series, and the resistance value between the first detection point A and the second detection point B is the sum of the resistance values of the N binding units, so that when at least one binding unit is not bound, such as broken circuit, the resistance value of at least one binding unit is larger, the resistance value between the first detection point A and the second detection point B is detected to exceed the preset resistance value, and the binding state can be judged to be abnormal according to the resistance value between the first detection point A and the second detection point B.
In addition, N binding units spaced among the plurality of binding units may also be connected in series, and the connection manner is similar to that in the embodiment of fig. 3, and will not be described in detail here.
Furthermore, in some embodiments of the present invention, as shown in fig. 2-4, the first connection element 111 includes a plurality of first binding points 1111, the second connection element 112 includes a plurality of second binding points 1121, each of the first binding points 1111 and the corresponding second binding point 1121 form a binding unit 1011, and the first binding point 1111 serves as a first end of the binding unit 1011, and the second binding point 1121 serves as a second end of the binding unit 1011.
It should be noted that the first binding point 1111 and the second binding point 1121 may be conductive strips. Conductive adhesive is further disposed between the first connecting element 111 and the second connecting element 112, so that each first binding point 1111 and the corresponding second binding point 1121 can conduct electricity after being bound.
Specifically, when the first connecting element 111 is bonded to the second connecting element 112, that is, the first connecting element 111 is bonded to the second connecting element 112, each first bonding point 1111 is connected to a corresponding second bonding point 1121, and a conductive adhesive is disposed between the two bonding points, so as to form a bonding unit 1011 capable of conducting electricity well. In this way, any N binding units are sequentially connected in series through the detection module 201, an external power supply is applied to the first detection point a and the second detection point B, the N binding units can form a conductive path, and then the resistance value between the first detection point a and the second detection point B is measured, so that the binding state of the first connecting piece 111 and the second connecting piece 121 can be judged.
It can be understood that the external power source may be a voltage source or a current source, when the external power source is a voltage source, the current sequentially flows through the N binding units through the first detection point a and then flows out through the second detection point B, at this time, the current of the conductive path may be measured, for example, the current flowing into the first detection point a, the current flowing through any one of the binding units, or the current flowing out of the second detection point B, and then the resistance value between the first detection point a and the second detection point B may be obtained according to the measured current and the voltage of the voltage source. When the external power source is a current source, the current flows through the N binding units in sequence through the first detection point A and then flows out through the second detection point B, at the moment, the voltage between the first detection point A and the second detection point B can be measured, and then the resistance value between the first detection point A and the second detection point B can be obtained according to the measured voltage and the current of the current source.
Further, as shown in fig. 5, the first detecting element 211 may abut against the exposed portion of the plurality of first binding points 1111 relative to the second connecting member 112, and the second detecting element 212 may abut against the exposed portion of the plurality of second binding points 1121 relative to the first connecting member 111.
That is, when the first connector 111 is coupled to the second connector 112, a portion of the first binding point 1111 is coupled to a portion of the second binding point 1121, while the remaining portion of the first binding point 1111 is exposed to facilitate coupling with the first sensing element 211 and the remaining portion of the second binding point 1121 is exposed to facilitate coupling with the second sensing element 212.
Specifically, the first connector 111 may be a connector of a display panel, and the second connector 112 may be a connector of a flexible circuit board. The first connector 111 and the second connector 112 may be mating connectors.
According to some embodiments of the present invention, as shown in fig. 5, the binding detection apparatus of the display apparatus further includes: and a pressing plate 202, wherein the pressing plate 202 is arranged opposite to the first detection assembly 111 so that the first detection assembly 211 is in close contact with the first ends of the N binding units, or the pressing plate 202 is arranged opposite to the second detection assembly 212 so that the second detection assembly 212 is in close contact with the second ends of the N binding units.
It should be noted that, when the pressing plate 202 is disposed opposite to the first detecting component 111, the pressing plate 202 and the first detecting component 111 may be disposed on two sides of the first connecting component 111, respectively, and the pressing plate 202 may enable the detecting end of the first detecting component 111 to abut against the exposed portion of the plurality of first binding points 1111 relative to the second connecting component 112. When the pressing plate 202 and the second detecting element 212 are disposed opposite to each other, the pressing plate 202 and the second detecting element 212 may be disposed on two sides of the second connecting element 112, respectively, so that the detecting end of the second detecting element 212 can better abut against the exposed portion of the plurality of second binding points 1112 opposite to the first connecting element 111 through the pressing plate 202.
For example, as shown in fig. 5, the second detecting element 212 is disposed below the second connecting element 112, and the pressing plate 202 can be disposed above the second connecting element 112, so that the pressure exerted by the pressing plate 202 can ensure that the detecting end of the second detecting element 212 can be well pressed against the exposed portion of the plurality of second binding points 1112 relative to the first connecting element 111, thereby ensuring accurate and effective detection.
In summary, according to the binding detection device of the display device in the embodiment of the invention, the detection module is configured to sequentially connect any N binding units in the plurality of binding units in series, connect the first ends of the N binding units connected in series to the first detection point, connect the second ends of the N binding units connected in series to the second detection point, and determine the binding state of the first connecting element and the second connecting element by measuring the resistance between the first detection point and the second detection point, so that the binding effect can be timely and accurately determined by testing the resistance of the N binding units connected in series, and the problem that the binding state of some binding points cannot be monitored because only one binding resistance can be measured is avoided.
