Description

Technical Field

[0001] The utility model relates to the technical field of display screen testing, in particular to a custom panel cell testing device. Background Art

[0002] With the continuous development of display panels, display devices have been applied to various industries. Thin Film Transistor (TFT) is a device. TFT display screen is the mainstream display device on various laptops and desktops. Each liquid crystal pixel on this type of display screen is driven by a thin film transistor integrated behind the pixel. Therefore, TFT display screen is also a type of active matrix liquid crystal display device. It is one of the best LCD color displays. TFT display has the advantages of high responsiveness, high brightness, high contrast, etc., and its display effect is close to that of CRT display.

[0003] During the production process of TFT LCD screens, large panels need to be cut and split using a press head to separate them into smaller pieces. Considering the economic applicability of display panel production, the masks designed for display panel molds rarely design only a single model of panel. Instead, an economical panelization method is adopted, that is, multiple sizes of panels are designed on one mask.

[0004] However, for panels made from masked panels, after the subsequent large panel cutting, they enter the electrical testing and lighting stage. Since a large panel has panels of different models and sizes, it is easy to cause mixing of goods when distinguishing them, which will extend the delivery cycle and affect product delivery efficiency. Summary of the invention

[0005] In the prior art, when large panels with display panels of different models and sizes are cut, mixing of goods is likely to occur, which results in a longer delivery cycle and a decrease in delivery efficiency.

[0006] To solve the above problems, a customized panel cell testing device is proposed. By setting customized buttons on the testing device, different test sequences can be selected. When the test frame is used to test panel cells of different sizes, abnormal signals will be displayed on the display unit due to the different test sequences, thereby screening out panel cells of various sizes, improving the electrical testing efficiency and avoiding the problem of mixed goods.

[0042] In the prior art, when large panels with display panels of different models and sizes are cut, mixing of goods is likely to occur, which results in a longer delivery cycle and a decrease in delivery efficiency.

[0043] Aiming at the above problems, a panel Cell testing device is proposed.

[0044] A custom panel cell test device includes a test frame, a control circuit 120, a test circuit 130, and a custom button; the test frame is used to fix the panel cell to be tested. The test circuit 130 is arranged on the test frame, one end of which is electrically connected to the control circuit 120, and the other end is used to be electrically connected to the panel cell to be tested, and is used to perform lighting test and screening according to the sizes of different panel cells obtained from cutting of a first large board; the custom button is electrically connected to the control circuit 120, and is used to select the corresponding test sequence according to the size of the panel cell.

[0045] like Figure 3 , Figure 3 It is a structural schematic diagram of a custom panel cell testing device in the utility model. Furthermore, the custom buttons include a first button 141 and a second button 142. The first button 141 and the second button 142 are electrically connected to the control circuit 120, respectively, for selecting a first test sequence and a second test sequence, respectively.

[0046] In this embodiment, the test circuit may be a conventional electrical test circuit for testing cells.

[0047] The test device also includes a frame 101, a bracket 170 and a base 160. Furthermore, the test device also includes a display unit 150. The display unit 150 can be a display screen of various types. The display screen can display abnormal information of the electrical test, and then screen the panel cells of different sizes. By setting a custom button on the test device to select different test sequences, when using the test stand to test the panel cells of different sizes, due to the different test sequences, an abnormal signal will be displayed on the display unit 150, and then the panel cells of various sizes will be screened out, thereby improving the efficiency of electrical testing and avoiding the problem of mixed goods.

[0048] In this embodiment, the test rack may include two, corresponding to the first button 141 and the second button 142 respectively. For the first test rack 111, it is used to test the first puzzle cell 211, and the first test sequence can be selected by the first button 141. For the second test rack 112, it is used to test the second puzzle cell 221, and the second test sequence can be selected by the second button 142. The first test sequence is different from the second test sequence, as shown in Figure 2 (a)-Figure 2 (b), Figure 2 (a)-Figure 2 (b) are respectively schematic diagrams of the structures of the first puzzle cell 211 and the second puzzle cell 221 in the present invention.

[0049] like Figure 1 , Figure 1It is a schematic diagram of the panel cell splicing structure of a large panel; the first large panel includes a first area 210 and a second area 220; the first area 210 is cut with a first unit size to obtain a plurality of first panel cells 211; the second area 220 is cut with a second unit size to obtain a plurality of second panel cells 221.

[0050] In this embodiment, the first panel cell 211 and the second panel cell 221 are both square in shape, and are used to make a square display screen. Preferably, the area of ​​the first panel cell 211 is larger than the area of ​​the second panel cell 221.

[0051] Preferably, the first test sequence is one of TRGB, RTGB, RGTB, and RGBT.

[0052] Preferably, the second test sequence is one of TRGB, RTGB, RGTB, and RGBT.

[0053] Figure 1 The schematic diagram of arranging the first panel cell211 (Panel A) and the second panel cell221 (Panel B) on a large board, in which there are two small pieces, the first panel cell211 (Panel A) and the second panel cell221 (Panel B). After production and cutting, the first panel cell211 (Panel A) and the second panel cell221 (Panel B) are mixed together, and electrical measurement and lighting are required to separate the goods. Since the two small pieces are close in size, if the first panel cell211 (Panel A) and the second panel cell221 (Panel B) are not distinguished, the small pieces will be mixed.

[0054] Referring to Figures 2 (a)-2 (b), in this embodiment, the structural designs of the first panel cell 211 (Panel A) and the second panel cell 221 (Panel B) are differentiated. The first test sequence of the quick test pad of the first panel cell 211 (Panel A) is TRGB, and the second test sequence of the quick test pad of the second panel cell 221 (Panel B) is RTGB. During electrical testing, the first panel cell 211 (Panel A) and the second panel cell 221 (Panel B) have their own corresponding first test racks 111 and second test racks 112. If the first test rack 111 is used to electrically test and light up the second panel cell 221 (Panel B), an abnormal display screen will appear, that is, an abnormal signal. Similarly, when the second test rack 112 is used to electrically test and light up the first panel cell 211 (Panel A), an abnormal display screen will also appear, that is, an abnormal signal. This phenomenon can be used to distinguish the first panel cell 211 (Panel A) and the second panel cell 221 (Panel B), and separate the goods to reduce the risk of mixed goods and improve production efficiency.

[0055] A custom panel cell testing device of the utility model is implemented, and different test sequences are selected by setting custom buttons on the testing device. When using the test frame to test panel cells of different sizes, due to the different test sequences, abnormal signals will be displayed on the display unit 150, and then panel cells of various sizes will be screened out, thereby improving electrical testing efficiency and avoiding the problem of mixed goods.

[0056] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
