[Previous technology] For TFT-LCD, the key components of the display structure include glass substrate, color filter, polarizer, driver 1C, liquid crystal material, alignment film, backlight module, conductive film, and other liquid crystal units. • Materials and chemical supplies to be used in the manufacturing process. The principle of LCD display is that the light from the backlight is first irradiated on the polarizer, and the light is polarized after passing through the polarizer (the molecules of each light have the same characteristics in energy, phase, frequency and direction). Polarized light passes through the liquid crystal. Because the arrangement of liquid crystal molecules is affected by the voltage generated by the electrodes, the liquid crystal can change the polarization angle of polarized light. The intensity of light produced by different polarization angles will be different. Through the red, blue, and green pixels of the color filter, a variety of pixels of different brightness and colors will be displayed. Finally, each pixel can be used to form various images and graphics that can be seen by the naked eye. # In the conventional technology, the detection of whether the pixel unit of the panel is damaged is generally achieved by a set of mechanical vision automatic detection equipment consisting of a detection probe, a flexible circuit board (FLEXIBLE PCB, FPCB), a computer, and a microscope. The detection probe, as shown in the first figure, is a double-ended needle (10), and the double-ended needle G0) is usually fixed and arranged on a base (12) by a predetermined number of probe bodies (11) at a predetermined fine pitch. ), The connection end (111) of each probe body (11) needs to be inserted into the connector (14) of the flexible circuit board (13), and the detection end (112) is in contact with the glass plate of the LCD test panel (19). Based on this, each pixel is detected. Therefore, the number and spacing of the probe bodies (Η) of the double-ended pins (10) and the design of the flexible circuit board need to correspond to LCD panels of different specifications. M283166 testing is performed in a dark room. With the LCD panel of different specifications, the applicable double-ended pins (10) and flexible circuit boards (13) are selected. The current problem is that replacing double-ended pins (10) and flexible circuit boards (13) in a dark room is quite intolerable. The connection end of each probe body （is difficult to insert into the connector (14) of the flexible circuit board ，, and the problem of misalignment often occurs. The double-ended pin ⑽ and the flexible circuit board (13) are easy to use. It is damaged, so that the operator needs to spend a long time debugging to confirm that it is a problem of the panel to be tested, or a problem of the double-headed pin (10) or the flexible circuit board (13), which is not in line with the principle of efficiency. [New content] In view of the above problems, the new person in this case proposes a specific solution. In this case, a device for detecting a pixel unit of a display panel includes a micro circuit board; a plurality of predetermined numbers of probe bodies are juxtaposed with respect to a fine pitch, one end of which is a connection end, and the other end is a detection end. The signal input unit connected to the circuit board of the Qing, the terminal is in contact with the glass plate of a display panel under test to correspond to each pixel; the number of right stems corresponds to the signal transmission line corresponding to the probe body, and the connection of each transmission line And the signal output section of the micro circuit board is fixedly connected; the ends of the signal transmission lines are integrated into a specific type of plug, and the plug can be connected to a specific connector of a circuit board of a detection computer, ·-base 'The above micro circuit board, the connection end of the probe body, and the connection creep of the signal transmission line are fixed; the base can be fixed—and to be displayed on the test panel. The purpose and effect achieved in this case is that the probe body is in contact with the display panel to be tested to form an electrical joint. The function of each pixel is converted into an electronic signal through the micro circuit board and output to the detection computer. To check whether the function of each pixel is normal. The second purpose and effect of this series is that the detection probe in this case can be made into different specifications in a modular manner according to the specifications of the panel to be inspected and display M283166. Replace with the specifications of the display panel during inspection. The third purpose and effect achieved in this case is that the detection probe in this case is mainly inserted into a specific connector of a computer circuit board with a specific type of plug, and both the plug and the circuit board connector have a specific type. 'Even if the operator is in a dark room, they can be quickly and correspondingly connected by groping. Compared with the operator, this case improves the practicality and convenience, and protects the detection probe and the detection computer. The circuit board is less likely to be damaged by incorrect bonding. The fourth purpose and efficacy achieved in this case is to improve the stability of the probe body and the accuracy of the test results. [Embodiment] As shown in the second, third, and fourth figures, the device for detecting a pixel unit of a display panel in this case includes: a micro circuit board (Micro PCB) (20); a predetermined number of probe bodies (30), The distance is juxtaposed, one end is a connection end (31), and the other end is a detection end (32); the connection end (31) is fixed to the signal input part of the micro circuit board (20), and the detection end (32) is connected with The glass plate contact of the LCD panel to be tested corresponds to each pixel; a number of signal transmission lines (40) corresponding to the probe body (32), a connection end (41) of each transmission line (40) and the microcircuit The signal output section of the board (20) is fixedly connected; as shown in the figure, the signal transmission lines (40) are bundled together by a heat-shrinkable sleeve (43); the signal transmission lines (40) are converted into conventional Cable (50) mode, the end of the cable (50) is integrated into a specific type of plug (51), and the plug (51) can be connected to a specific connector of the circuit board of the detection computer (80) A base (60), connecting the micro circuit board (20), the connection end (31) of the probe body (30), and the signal transmission line (40); Connection terminal (41) to be fixed to the cover. Therefore, the probe end (32) of the probe body (30) protrudes from the outside of the base (60) by a predetermined exposed length (L1), and its exposed length (li) 7 M283166 'is obviously The length (L2) fixed by Xiaochun's base ⑽). The base 固定) is further provided with a plurality of fixing holes (61), so that the fixing element is fixed on the testing machine. As shown in the fifth picture ..._ the panel ⑽ is positioned at the stage (71) i ^ which can be the vertical and horizontal axis (χ, γ axis) axis, the glass panel of the LCD panel touches the pixel point, and with the probe The main body ⑽) is in contact with the display panel (70) to be tested to form an electrical connection, and the function of each pixel is converted into an electronic signal through the micro circuit board 输出 to be output to a detection computer (80). Check whether the function of each pixel is normal. _ The detection probe in this case also needs to be made in accordance with the display panel specifications (such as 15 忖, 17 pairs, 19 · _ · _), because the structure described in this case is so modular that it can be made without The detection probe of the grid is replaced in accordance with the specifications of the display panel during the detection. The test is performed in a dark room. The operator plugs the cable ⑽ a specific type of plug at the end 谓) into the test computer ⑽) specific connector on the circuit board, and both the plug (51) and the circuit board connector have The specificity of the response (commonly known as the foolproof design), even in a dark room, the operator can quickly connect the two correspondingly by fumbling to complete the connection between the detection probe and the detection computer. This case is quite practicable and convenient compared with the prior art, and it is less likely that the inspection probe pin and the detection computer circuit board will be damaged by the wrong connection. In addition, the probe end (32) of the probe body (30) of the present case protrudes outside the base (60) with a predetermined bare length, and its bare length is significantly smaller than that fixed by the base.) Length (L2). This can improve the stability of the probe body and improve the accuracy of the test results. Although this case is described with a preferred embodiment, those skilled in the art can make various changes under the spirit of the "case-inspired" case. The above-mentioned embodiments are only used to illustrate the case, not for use. In order to limit the scope of this case. For example, any modification or change that does not violate this case belongs to the scope of patent application in this case.
