[0030] The screen needs to be tested before assembly to ensure the yield of the final product. Due to cost considerations, most small businesses cannot afford to purchase automated production lines for screen testing, so many small businesses complete screen testing manually. Specifically, the interfaces usually set up on the screen to be tested include TP interface, light valve interface, screen backlight interface, screen power supply interface and screen signal interface. Therefore, the technician can plug the TP line on the test terminal into the TP interface, the light valve line into the light valve interface, the screen backlight line into the screen backlight interface, the screen power supply line into the screen power supply interface and the screen signal into the screen signal interface, and then start the test program for testing. However, the screen to be tested is basically unprotected before assembly, so the probability of damaging the screen to be tested in this way is also slightly higher. For example, due to the negligence of the technician, the screen to be tested falls to the ground, thereby breaking the screen to be tested.
[0031] Therefore, there are screen test jigs on the market to assist manual testing, and screen test jigs can at least play a certain protective role during the manual testing process. However, most screen test jigs on the market are specialized, that is, a screen test jig is usually only suitable for one type of screen. This is because the screen test jigs on the market also pursue the convenience of wiring, which requires that the relevant circuits and / or structures of the screen test jig need to be set according to the interface on the screen, that is, it is affected by the interface position of the screen. Therefore, if the manufacturer chooses the manual testing method and there are testing requirements for multiple types of screens, the manufacturer needs to purchase multiple dedicated screen test jigs, resulting in increased production costs.
[0032] To this end, an embodiment of the present application provides a screen testing fixture and a screen testing system. The screen testing fixture can be compatible with various types of screens to be tested, thereby solving the problems existing in the prior art.
[0033] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0034] The screen test fixture 100 provided in the embodiment of the present application is shown in FIG. Figures 1 to 5 , may include a base 110 , two screen supports 120 , a splitter 130 , a plurality of test interfaces 140 , a plurality of first branch interfaces 150 and a plurality of second branch interfaces 160 .
[0035] Two screen brackets 120 are symmetrically arranged at the left and right ends of the base 110 with respect to the vertical axis of the base 110, and are used to place the screen 200 to be tested. The splitter 130 is arranged on the base 110 and is located in the middle area. The middle area mentioned here refers to the middle area of the base 110 in the vertical direction. In this case, it can be understood that the two screen brackets 120 are respectively arranged in the left and right areas. A plurality of test interfaces 140 are arranged in front of the base 110. For example, the plurality of test interfaces 140 may include a part or all of the TP interface 141, the light valve interface 142, the screen backlight interface 143, the screen power supply interface 144 and the screen signal interface 145.
[0036] The demultiplexer 130 is used to divide the test interface 140 into a first demultiplexer 150 and a second demultiplexer 160, that is, to divide the test interface 140 into two. Exemplarily, the TP interface 141 is divided into two demultiplexers (151, 161), the light valve interface 142 is divided into two demultiplexers (152, 162), the screen backlight interface 143 is divided into two demultiplexers (153, 163), the screen power supply interface 144 is divided into two demultiplexers (154, 164), and the screen signal interface 145 is divided into two demultiplexers (155, 165). It should be noted that the demultiplexer 130 is already a prior art, and the embodiments of the present application do not limit the implementation thereof.
[0037] A plurality of first tapping ports 150 are disposed on one of the screen brackets 120, for example, Figure 2 As shown, the tapping ports (151, 152, 153, 154, 155) are arranged on the left screen support 120. A plurality of second tapping ports 160 are arranged on another screen support 120, for example, Figure 3 As shown, the tapping ports ( 161 , 162 , 163 , 164 , 165 ) are arranged on the right screen support 120 .
[0038] In the embodiment of the present application, the test interface 140 is used to connect the test terminal, and one of the first sub-interface 150 and the second sub-interface 160 is used to connect the screen to be tested 200. Exemplarily, first, one of the pair of sub-interfaces can be connected to the screen to be tested 200, for example, assuming that the first sub-interface 151 is closer to the TP interface of the screen to be tested 200, then the first sub-interface 151 is connected to the TP interface of the screen to be tested 200; similarly, the second sub-interface 162 (assuming) closer to the light valve interface of the screen to be tested 200 can be connected to the light valve interface of the screen to be tested 200, the second sub-interface 163 (assuming) closer to the screen backlight interface of the screen to be tested 200 can be connected to the screen backlight interface of the screen to be tested 200, the first sub-interface 154 (assuming) closer to the screen power supply interface of the screen to be tested 200 can be connected to the screen power supply interface of the screen to be tested 200, and the first sub-interface 155 (assuming) closer to the screen signal interface of the screen to be tested 200 can be connected to the screen signal interface of the screen to be tested 200. Then, the TP line on the test terminal can be plugged into the TP interface 141, the light valve line can be plugged into the light valve interface 142, the screen backlight line can be plugged into the screen backlight interface 143, the screen power line can be plugged into the screen power interface 144, and the screen signal line can be plugged into the screen signal interface 145. In this way, the test program can be started to perform the test.
[0039] It can be seen that in the screen test fixture 100 in the embodiment of the present application, the splitter 130 divides the test interface 140 into two sub-interfaces (150, 160). In this way, after the screen 200 to be tested is placed on the screen bracket 120, the sub-interface (150, 160) that is closer to the interface of the screen 200 to be tested is selected for connection. In this way, it will not be affected by the interface position of the screen 200 to be tested, and can be applicable to more types of screens, thereby improving compatibility compared with the prior art.
[0040] In some embodiments, Figure 4 As shown, the screen bracket 120 is provided with an inclined L-shaped structure 121 (shown as the oblique line filled part in the figure), and the screen bracket 120 realizes the function of placing the screen 200 to be tested through this L-shaped structure 121. In some embodiments, the inclination angle of the L-shaped structure 121 is between 25 degrees and 35 degrees, that is, the angle θ shown in the figure is greater than or equal to 25 degrees and less than or equal to 35 degrees. This inclined setting mode can make the screen 200 to be tested more stable after placement and facilitate the interface connection of the screen 200 to be tested. In some embodiments, the surface of the L-shaped structure 121 is provided with a soft material layer (not shown in the figure) to better protect the screen 200 to be tested. In some embodiments, the end of the short side of the L-shaped structure 121 extends upward to form a protrusion 122. When the screen 200 to be tested tilts forward due to an accident or the like, the protrusion 122 can prevent the screen 200 to be tested from tilting forward, prevent the screen 200 to be tested from falling, and play a role in protecting the screen to be tested. Exemplarily, the length of the protrusion 122 is between 5 cm and 8 cm, that is, the length of the protrusion 122 is greater than or equal to 5 cm and less than or equal to 8 cm. This length setting method can meet the size of common screens on the market.
[0041] In some embodiments, Figure 4As shown, the screen bracket 120 is provided with two L-shaped legs 123, and the base 110 is provided with an L-shaped groove 111 corresponding to the two L-shaped legs. It can be understood that the screen bracket 120 can be fixed on the base by inserting the L-shaped legs 123 of the screen bracket 120 into the L-shaped groove 111 of the base 110. In addition, this structural design can also realize the adjustment function to adapt to more sizes of screens 200 to be tested and adjust the position of the screen 200 to be tested. Exemplarily, if the size of the screen 200 to be tested is small, the screen brackets 120 on the left and right sides can be moved inward respectively, so that the adjusted screen bracket can be placed for the screen 200 to be tested with a smaller size, thereby improving applicability and compatibility. Exemplarily, if the position of the screen 200 to be tested needs to be moved for more convenient wiring (assuming that it needs to be moved to the right), the screen bracket 120 on the left can be moved inward, and the screen bracket 120 on the right can be moved outward, so as to achieve the purpose of adjusting the position of the screen 200 to be tested, thereby improving convenience. In some embodiments, the length of the L-shaped groove 111 is between 2 cm and 4 cm, that is, the length of the L-shaped groove 111 is greater than or equal to 2 cm and less than or equal to 4 cm. Such a length setting method can achieve a better adjustment effect.
[0042] In some embodiments, the screen bracket 120 is provided with a magnet, and the surfaces of the first branch interface 150 and the second branch interface 160 are provided with iron sheets, that is, the surface of each branch interface is provided with an iron sheet. Figure 5 As shown, a magnet 124 is provided on the left screen bracket 120, and an iron sheet 1501 is provided on the surface of the first tapping interface 150 (including 151, 152, 153, 154, 155). It is more convenient to fix the tapping interface by magnetic attraction.
[0043] In some embodiments, Figure 2 , Figure 3 and Figure 5 As shown, a pair of first branch interfaces 150 and second branch interfaces 160 are arranged symmetrically about the vertical axis of the splitter 130. For example, in the above example, the first branch interface 151 and the second branch interface 161 are a pair of branch interfaces, the first branch interface 152 and the second branch interface 162 are a pair of branch interfaces, the first branch interface 153 and the second branch interface 163 are a pair of branch interfaces, the first branch interface 154 and the second branch interface 164 are a pair of branch interfaces, and the first branch interface 155 and the second branch interface 165 are a pair of branch interfaces. These five pairs of branch interfaces are arranged symmetrically. Figure 2 , Figure 3 and Figure 5 As shown, a plurality of pairs of first tap interfaces 150 and second tap interfaces 160 are evenly spaced and arranged along the vertical axis of the demultiplexer 130 . For example, in the above example, five pairs of tap interfaces are evenly spaced and arranged.
[0044] Based on this, one of the pair of first tapping interfaces 150 and second tapping interfaces 160 is provided with a cable reel 131; the two cable reels 131 in the two adjacent pairs of first tapping interfaces 150 and second tapping interfaces 160 are respectively provided on the left and right sides. Figure 5 As shown, the reel 131 in the first branch interface 151 and the second branch interface 161 is arranged on the left, the first branch interface 152 and the second branch interface 162 are arranged on the right, and so on. Such an arrangement not only ensures that one of each pair of branch interfaces has an extended function, but also maximizes the use of space. It should be noted that the reel 131 is already a prior art and is not limited in the embodiments of the present application.
[0045] In addition, the present application embodiment also provides a screen testing system, such as Figure 6 As shown, the screen test fixture 100, the screen to be tested 200 and the test terminal as described in any of the above embodiments may be included. For specific implementation, please refer to the above discussion, and the embodiments of this application will not be repeated.
