Description

Technical Field

[0001] This application relates to the field of display technology, and more particularly to a lamp testing device. Background Technology

[0002] Display screens are used to display images and colors. During the manufacturing process, multiple inspection procedures are required. One crucial procedure is testing the cut display screens to confirm the absence of defects in the displayed images and colors. Taking a Liquid Crystal Display (LCD) as an example, the testing process first involves inputting a test signal to the LCD screen, causing its pixels to display colors. Then, a defect detection device checks each pixel individually to ensure its quality; this process is called light-on testing. Light-on testing prevents defective products from entering the next production process, ensuring that the finished product meets customer quality requirements.

[0003] However, the lighting test of the display screen involves a series of processes, including lighting, debugging, and testing. Each process is carried out by different instruments and equipment, resulting in a large number of instruments and equipment and increasing the lighting test cost of the display screen. Utility Model Content

[0004] In view of the above, it is necessary to provide a lighting test device to solve the problem of high lighting test cost of display screen due to the large number of instruments and equipment required for lighting test.

[0005] This application provides a lighting test device for testing a display screen. The lighting test device includes a communication processor, a power manager, a signal converter, and an optical measuring instrument. The input terminal of the power manager is connected to the communication processor, and the output terminal of the power manager is connected to the display screen. The input terminal of the signal converter is connected to a computer device, and the output terminal of the signal converter is connected to the display screen. The optical measuring instrument is connected to the communication processor. Specifically: the power manager manages the power of the display screen, outputting a power voltage to the display screen or stopping the power voltage output based on the electrical signal output by the communication processor; when the power manager outputs the power voltage to the display screen, the signal converter performs signal conversion based on a first type of image signal output by the computer device, and outputs a converted second type of image signal to the display screen, causing the display screen to display a preset image; the optical measuring instrument measures the optical parameters of the display screen when displaying the preset image and transmits the optical parameters back to the communication processor; the communication processor outputs the optical parameters to the computer device and receives the lighting test results sent by the computer device.

[0006] In some embodiments, there are multiple signal converters, with the input of each signal converter connected to the computer device and the output of each signal converter connected to a display screen of the corresponding signal type.

[0007] In some embodiments, the optical measuring device includes a connecting part and a measuring end. The measuring end is connected to the communication processor through the connecting part. The measuring end is attached to the surface of the display screen and is used to measure the optical parameters of the display screen and transmit the optical parameters to the communication processor through the connecting part.

[0008] In some embodiments, the measuring end includes a brightness sensor.

[0009] In some embodiments, the communication processor is connected to the computer device and the display screen respectively, and is used to receive debugging parameters determined by the computer device based on the lamp test results, and output the debugging parameters to the chip of the display screen to configure the display screen.

[0010] In some embodiments, the lighting test device further includes a signal amplifier, the input of which is connected to the signal converter, and the output of which is connected to the display screen. The signal amplifier is used to receive a second type of image signal output by the signal converter, amplify the second type of image signal, and output the amplified image signal to the display screen.

[0011] In some embodiments, the lighting test device further includes a first housing compartment for accommodating the communication processor, the power manager, the signal converter, and the optical measuring instrument.

[0013] In some embodiments, the first and second accommodating compartments have multiple openings, each opening being used to provide a communication interface.

[0014] In some embodiments, the first receiving compartment includes a first surface and a second surface arranged along a preset direction, the lighting test device includes a gripping part and an anti-slip member, the gripping part is disposed on the first surface and spaced apart from the second receiving compartment, and the anti-slip member is disposed on the second surface.

[0015] As can be seen from the above technical solution, the lighting test equipment includes a communication processor, a power manager, a signal converter, and an optical measuring device. The power manager is used for power management of the display screen. Based on the electrical signal output by the communication processor, the power manager outputs a power voltage to the display screen or stops outputting a power voltage. When the power manager outputs the power voltage to the display screen, the signal converter performs signal conversion based on the first type of image signal output by the computer device and outputs the converted second type of image signal to the display screen, causing the display screen to display a preset image. The optical measuring device measures the optical parameters of the display screen when displaying the preset image and sends the optical parameters back to the communication processor.

[0023] Explanation of key component symbols:

[0024] The device includes: a lighting test device 100, a first receiving compartment 10, a second receiving compartment 20, HDMI signal input interfaces 101 and 102, an LVDS signal output interface 103, V-BY-ONE signal output interfaces 104, 107, and 108, a multi-function interface 105, a V-BY-ONE signal input interface 106, a communication processor 11, a power manager 12, a signal converter 13, an optical measuring instrument 14, a connector 141, a measuring end 142, a first surface 15, a second surface 16, a computer device 200, and a display screen 300. Detailed Implementation

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] The light-on test for a display screen involves several steps, including lighting, adjustment, and inspection. For example, a test signal is first input to the display screen to make its pixels display color. Next, based on the lighting, the display screen's parameters are optimized to achieve the desired display effect. Finally, a defect detection device checks each pixel individually to ensure it is functioning correctly; this process is called light-on testing.

[0027] However, the lighting test of a display screen involves several processes, including lighting, debugging, and testing, each performed by different instruments and equipment. For example, different models of display screens require different lighting devices during the lighting process. In the debugging process, multiple debugging devices are needed to configure the timing controller and program the chips. In the testing process, optoelectronic equipment is required to measure the optical parameters of the display screen. Therefore, the use of multiple instruments and equipment during the lighting test of a display screen increases the cost of the lighting test.

[0028] In view of the above problems, this application provides a lighting test device that integrates lighting, debugging and testing functions into the same device, avoiding the use of multiple instruments and equipment for lighting tests and reducing the lighting test cost of the display screen.

[0029] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the connection relationship of the lighting test equipment provided in the embodiments of this application. Figure 2This is a schematic diagram of signal transmission for lighting testing provided in an embodiment of this application. This application provides a lighting testing device 100 for performing lighting tests on a display screen 300. The lighting testing device 100 includes a communication processor 11, a power manager 12, a signal converter 13, and an optical measuring instrument 14. The communication processor 11 is connected to the power manager 12, the signal converter 13, and the optical measuring instrument 14, respectively, via wired connections. For example, the communication processor 11 is connected to the power manager 12, the signal converter 13, and the optical measuring instrument 14 via signal lines.

[0030] In some embodiments, the communication processor 11 serves as the global control center of the lighting test equipment 100, and can control the remaining components within the lighting test equipment 100 based on a microcontroller. The type of microcontroller can be set according to actual needs; for example, the microcontroller may include an STMicroelectronics 32-bit (STM32) microcontroller.

[0031] In some embodiments, the communication processor 11 is connected to the computer device 200 via a signal line and is used to receive a lighting test command sent by the computer device 200. The lighting test command is used to instruct the display screen 300 to perform a lighting test. The communication processor 11 parses the lighting test command to control other components within the lighting test device 100. For example, after receiving the lighting test command, the communication processor 11 outputs an electrical signal to the power manager 12 and transmits the electrical signal to the power manager 12.

[0032] In some embodiments, the communication processor 11 is connected to the display screen 300 via a signal line, and is used to receive debugging parameters output by the computer device 200, and output the debugging parameters to the chip in the display screen 300 to configure the display screen 300. The display screen 300 may contain multiple chips; for example, it may include a timing control (TconCode) chip and a driver board memory (X-board flash) chip, with different chips corresponding to different communication types. For example, the TconCode chip needs to be connected to the communication processor 11 via an Inter-Integrated Circuit (IIC) bus, and the X-board flash chip needs to be connected to the communication processor 11 via a Serial Peripheral Interface (SPI) bus. The debugging parameters can be obtained by the computer device 200 through analysis and processing of the lamp test results. Debugging parameters may include contrast, brightness, color gamut mapping, refresh rate, white balance parameters, etc., and are not limited here. In this embodiment, the communication processor 11 is connected to the computer device 200 and the display screen 300 respectively. The computer device 200 analyzes the lighting test results and outputs debugging parameters to the communication processor 11. The communication processor 11 outputs the debugging parameters to the display screen 300. The display screen 300 adjusts the relevant parameters originally stored in the chip according to the debugging parameters, so that the lighting test device 100 has a debugging function.

[0033] In some embodiments, the power manager 12 can be used for power management of the display screen 300. The operating state of the power manager 12 can include outputting power voltage and stopping outputting power voltage. The input terminal of the power manager 12 is connected to the communication processor 11, and the output terminal of the power manager 12 is connected to the display screen 300. It is used to output power voltage to the display screen 300 based on the electrical signal output by the communication processor 11, so that the display screen 300 is powered on, or to stop outputting power voltage to the display screen 300, so that the display screen 300 is powered off. The electrical signal can include low-level signals and high-level signals. For example, when the electrical signal is a high-level signal, the power manager 12 outputs power voltage to the display screen 300. When the electrical signal is a low-level signal, the power manager 12 stops outputting power voltage to the display screen 300. In this embodiment, the power manager 12 switches its operating state according to the electrical signal of the communication processor 11. By outputting power voltage to the display screen or stopping outputting power voltage, the power manager 12 realizes power management of the display screen 300, enabling the lighting test device 100 to have a lighting function.

[0034] In some embodiments, there are multiple signal converters 13. The input terminal of each signal converter 13 is connected to the computer device 200, and the output terminal of each signal converter 13 is connected to a corresponding type of display screen 300. For example, there are two signal converters 13, referred to as the first converter and the second converter, respectively. The output terminal of the first converter is a 30-pin output terminal, and the output terminal of the second converter is a 51-pin output terminal. The 30-pin output terminal is used to connect to the display screen 300 with a low-voltage differential signaling (LVDS) signal type, and the 51-pin output terminal is used to connect to the display screen 300 with a V-by-One signal type. In some embodiments, the input terminal of the signal converter 13 is connected to the computer device 200 to receive a first type of image signal sent by the computer device 200. The signal converter 13 is used to perform signal conversion on the first type of image signal and output the converted second type of image signal to the corresponding display screen 300 through the output terminal, so that the display screen 300 displays the image corresponding to the second type of image signal (for ease of description, this application simply refers to it as a "preset image"). The image signal sent by the computer device 200 can be of the High Definition Multimedia Interface (HDMI) signal type. The signal converter 13 needs to convert the HDMI signal type image signal into image data compatible with the display screen 300. For example, the first converter is used to convert the HDMI signal type image signal into the LVDS signal type (i.e., the second type is the LVDS signal type), and the second converter is used to convert the HDMI signal type image signal into the V-by-One signal type (i.e., the second type is the V-by-One signal type). In this embodiment, the signal converter 13 performs signal conversion on the uniform first type image signal, converting it into a signal type compatible with the display screen 300 (i.e., the second type), so that the display screen 300 can display image data normally, ensuring the lighting test effect of the lighting test device 100. In addition, by setting multiple signal converters 13, each signal converter 13 is connected to different types of display screens 300, so that the lighting test device 100 can perform lighting tests on multiple different types of display screens 300, improving the adaptability and compatibility of the device.

[0035] In some embodiments, please refer to Figure 3 , Figure 3 This is a schematic diagram of the structure of the optical measuring device provided in the embodiments of this application. Figure 3As shown, the optical measuring device 14 includes a connecting part 141 and a measuring end 142. The measuring end 142 is connected to the communication processor 11 through the connecting part 141. The measuring end 142 is attached to the surface of the display screen 300 and is used to measure the optical parameters of the display screen 300 and transmit the optical parameters to the communication processor 11 through the connecting part 141. The connecting part 141 may include a signal line. The measuring end 142 may include a brightness sensor or other sensors used for measuring optical parameters. For example, the brightness sensor is placed at a designated position on the display screen 300, and the optical parameters of the display screen 300 can be monitored by the brightness sensor. The optical parameters may include the flicker index. The designated position can be set according to actual needs; for example, the designated position may include the center position or the edge position of the display screen 300, without limitation.

[0036] In some embodiments, one end of the optical measuring device 14 is connected to the communication processor 11 via a connector 141, and the other end (i.e., the measuring end 142) extends from the lighting test device 100. After receiving a lighting test command from the computer device 200, the communication processor 11 generates an electrical signal and transmits the electrical signal to the optical measuring device 14. Based on the electrical signal, the optical measuring device 14 activates the brightness sensor and uses the brightness sensor to monitor the flicker index of the display screen 300. The electrical signal may include a high-level signal or a low-level signal. For example, when the electrical signal output by the communication processor 11 to the optical measuring device 14 is a high-level signal, the optical measuring device 14 activates the brightness sensor; when the electrical signal output by the communication processor 11 to the optical measuring device 14 is a low-level signal, the optical measuring device 14 deactivates the brightness sensor. In this embodiment, the optical parameters of the display screen 300 are measured by the optical measuring device 14, enabling the lighting test device 100 to have a testing function. The optical measuring device 14 extends from the lighting test device 100 through the connecting part 141, so that the measuring end 142 can flexibly determine the display effect of the display screen 300, improving the testing flexibility of the lighting test device 100. In addition, the optical measuring device 14 turns the measuring end 142 on or off according to the electrical signal output by the communication processor 11, which can avoid power consumption of the lighting test device 100.

[0037] In some embodiments, after determining the optical parameters of the display screen 300, the optical measuring device 14 transmits the optical parameters to the communication processor 11 via the connection portion 141. Upon receiving the optical parameters, the communication processor 11 outputs the optical parameters to the computer device 200. The computer device 200 determines the illumination test result of the display screen 300 based on the optical parameters. The illumination test result may include whether the display screen 300 passed the test or failed the test.

[0038] In some embodiments, the lighting test device 100 further includes a signal amplifier, which is connected to both the signal converter 13 and the display screen 300. The input terminal of the signal amplifier is connected to the signal converter 13, and the output terminal of the signal amplifier is connected to the display screen 300. The signal amplifier is used to receive the second type of image signal converted by the signal converter 13, amplify the second type of image signal, and output the amplified image signal to the display screen 300, so that the amplified image signal can meet the high frame rate requirements of the display screen 300.

[0039] For example, if the frame rate of the display screen 300 is less than or equal to the frame rate threshold, a lighting test can be performed using the communication processor 11, power manager 12, signal converter 13, and optical measuring device 14 within the lighting test device 100. If the frame rate of the display screen 300 is greater than the frame rate threshold, a lighting test can be performed using the communication processor 11, power manager 12, signal converter 13, optical measuring device 14, and signal amplifier within the lighting test device 100. Taking the case where the frame rate of the display screen 300 is greater than the frame rate threshold as an example, the power manager 12 outputs a power supply voltage to the display screen 300 or stops outputting a power supply voltage based on the electrical signal output by the communication processor 11. The input terminal of the signal converter 13 is connected to the computer device 200, and the output terminal of the signal converter 13 is connected to the display screen 300. It is used to convert the first type of image signal sent by the computer device 200 and output the converted second type of image signal to the signal amplifier. The signal amplifier amplifies the second type of image signal, ensuring that the amplified image signal meets the high frame rate requirements of the display screen 300, and outputs the amplified image signal to the display screen 300. The display screen 300 displays a preset image based on the amplified image signal. The optical measuring instrument 14 is connected to the communication processor 11 and is used to measure the optical parameters of the display screen 300 when displaying the preset image, and outputs the optical parameters to the communication processor 11. The communication processor 11 outputs the optical parameters to the computer device 200 and receives the lighting test results sent by the computer device 200. The frame rate threshold can be set according to actual needs; for example, the frame rate threshold can be 102Hz. This embodiment of the application amplifies the low frame rate image signal using a signal amplifier to obtain a high frame rate image signal, and transmits the high frame rate image signal to the display screen 300, ensuring that the image signal meets the frame rate requirements of the display screen 300, thus improving the adaptability and compatibility of the lighting test device 100.

[0040] Please see Figure 4 , Figure 4 This is a schematic diagram of the lighting test equipment provided in an embodiment of this application. Figure 4As shown, the lighting test equipment 100 includes a first receiving compartment 10 and a second receiving compartment 20. The first receiving compartment 10 is used to house the communication processor 11, the power manager 12, the signal converter 13, and the optical measuring instrument 14. Figure 4 (Not shown in the image). The communication processor 11 is connected to the power manager 12, the signal converter 13, and the optical measuring instrument 14 via signal lines. The positional relationship of the communication processor 11, the power manager 12, the signal converter 13, and the optical measuring instrument 14 in the first receiving compartment 10 can be set according to actual needs and is not limited here. The second receiving compartment 20 is detachably connected to the first receiving compartment 10 and is used to house the signal amplifier (…). Figure 4 (Not shown in the image). This embodiment of the application sets up two storage compartments: the first storage compartment 10 is used to store components that can meet most frame rate requirements, and the second storage compartment 20 is used to store components that meet specific frame rate requirements, thereby making the lighting test device 100 highly compatible.

[0041] Please refer to the following: Figure 5 , Figure 6 and Figure 7 . Figure 5 This is a schematic diagram of the communication interface provided in the first embodiment of this application. Figure 6 This is a schematic diagram of the communication interface provided in the second embodiment of this application. Figure 7 This is a schematic diagram of the communication interface provided in the third embodiment of this application. In some embodiments, the first receiving compartment 10 and the second receiving compartment 20 have multiple openings, each opening being used to set up a communication interface. The type of the communication interface is related to the type of signal line of the components in the first receiving compartment 10. The number and position of the openings can be set according to actual needs and are not limited here. For example, the first receiving compartment 10 can have 5 openings, respectively providing 2 HDMI signal input interfaces (denoted as HDMI signal input interface 101 and HDMI signal input interface 102), 1 LVDS signal output interface (denoted as LVDS signal output interface 103), 1 V-BY-ONE signal output interface (denoted as V-BY-ONE signal output interface 104), and a multi-function interface (denoted as multi-function interface 105). The second receiving compartment 20 can have three openings, each providing one V-BY-ONE signal input interface (denoted as V-BY-ONE signal input interface 106) and two V-BY-ONE signal output interfaces (denoted as V-BY-ONE signal output interface 107 and V-BY-ONE signal output interface 108, respectively). This embodiment of the application, by creating multiple openings in the receiving compartment and providing communication interfaces at these openings, enables multiple components within the lighting test equipment 100 to communicate and connect, as well as allows the lighting test equipment 100 to communicate with the computer equipment 200, ensuring the normal operation of the lighting test equipment 100.

[0042] In some embodiments, the first receiving compartment includes a first surface 15 and a second surface 16 arranged along a preset direction. The lighting test device 100 includes a grip (not shown) and an anti-slip component (not shown). The grip is disposed on the first surface 15 of the first receiving compartment 10 and spaced apart from the second receiving compartment 20. The anti-slip component is disposed on the second surface 16 of the first receiving compartment 10. The grip is shaped to be easily held by a human hand, for example, an approximate cylinder, an elliptical cylinder, or a curved surface with ergonomic features. The anti-slip component is made of a material with a high coefficient of friction, such as a soft elastomer like silicone rubber or a textured hard plastic. This embodiment of the application improves the portability of the lighting test device 100 by providing a grip, making it easier to move. The anti-slip component enhances the anti-slip effect of the lighting test device 100.

[0043] The lighting test device 100 provided in this application embodiment manages the power of the display screen 300 through a power manager 12 and outputs corresponding type image signals to the display screen 300 through a signal converter 13, thereby realizing the lighting process of the display screen 300; it measures the optical parameters of the display screen 300 when displaying a preset image through an optical measuring instrument 14, thereby realizing the detection process of the display screen 300; and it receives the lighting test results sent by the computer device 200 through a communication processor 11, thereby realizing the debugging process of the display screen 300. The above device integrates the lighting, debugging and testing functions into a single device, avoiding the use of multiple instruments and equipment for lighting tests and reducing the lighting testing cost of the display screen 300.
