Description

Technical Field

[0001] The present application relates to the technical field of display screen testing, and in particular to a display screen testing system. Background Art

[0002] Before the display screen leaves the factory, in addition to the need for screen dot detection to determine whether there are any display abnormalities on the screen, it is also necessary to undergo aging testing to ensure the stability of the performance of the display screen during later use.

[0003] The aging furnace for aging test usually has several compartments (for example, four), which are used to place the display screen to be tested and a trolley equipped with multiple pattern generators (PG). The pattern generator is used to obtain the point screen data from the computer equipment outside the furnace (called the host computer in the industry) and make the tested display screen display the test screen based on the point screen data. For example, if the aging furnace has a total of 4 compartments, there will generally be 4 trolleys pushed into the compartment for subsequent testing. The overall structural process of the entire test is as follows:

[0004] After the trolley containing the pattern generator is pushed into the corresponding compartment of the aging furnace, the power connector is connected to connect the power supply line and communication line. The power source in the aging furnace provides power to start the pattern generator. After the pattern generator is started, according to the IP address set by the dialer, and the ports 3956 (command port) and 43690 (data port) set by the program, a socket socket node based on the UDP protocol for network communication is created. The computer equipment outside the furnace also creates two network communication socket nodes based on the UDP protocol. The two socket socket nodes use the two local ports opened by the computer equipment (for example: 3957, 5002), the target IP and the target port to interact with the pattern generator, where the target IP and the target port are the pattern generator's IP + command port and IP + data port respectively. The pattern generator is controlled through a network link with a network cable and a switch and based on the above software design.

[0005] Under this control, a computer device needs to issue control instructions to hundreds of pattern generators, and the IP correspondence between the computer device and the hundreds of pattern generators is fixed in advance, for example:

[0006] 1. Before the burn-in test, the staff responsible for installing the trolley will manually dial the IP address of each pattern generator to a fixed address. Assuming there are 200 pattern generators participating in the burn-in test, the IP address of PG1 will be dialed to: 192.168.5.1, the IP address of PG2 will be dialed to: 192.168.5.2, ..., the IP address of PG200 will be dialed to: 192.168.5.200; PG1-PG18 will be placed on the first trolley, PG19-PG36 will be placed on the second trolley; ..., the corresponding first trolley will be placed in the first cabin;

[0007] 2. When establishing communication, the computer automatically assumes that the first vehicle is placed in the first compartment, and that the IP addresses of the PGs in the first compartment are in the 192.168.5.1-192.1168.5.18 range. Therefore, the computer sends control instructions for PG1 to the IP addresses 192.168.5.1... and for PG18 to the IP address 192.168.5.18. This implies that if the second vehicle is mistakenly placed in the first compartment, the target IP addresses in the sockets used by the computer to send instructions and data to the first compartment will still be 192.168.5.1-192.1168.5.18. However, since the IP addresses of the pattern generators on the second vehicle are 192.168.5.19-192.1168.5.36, normal communication cannot be established.

[0008] However, in actual applications, because each compartment of the aging furnace needs to frequently replace equipment, products to be tested, etc., the trolleys in the compartments are often pushed out and pushed in. Since the aging test lines are generally configured with multiple lines, assuming there are 4 test lines and each test line has 4 compartments, there are a total of 16 trolleys corresponding to each compartment. Therefore, in the process of frequently pushing and pushing the trolleys, it is easy to confuse the trolleys in adjacent compartments. When the compartment is pushed in again, the trolley often fails to be pushed into the corresponding compartment, resulting in communication errors and affecting work efficiency. On the other hand, because the IP address corresponding to each compartment is fixed, the spare trolley of each compartment (the spare trolley refers to the spare material used to replace the trolley when the working trolley fails) can only be used in the compartment. If the trolleys in other compartments fail, the spare trolleys cannot be used directly, and the IP address information of the PG on the spare trolley needs to be manually changed, which makes the aging test extremely cumbersome and affects the production efficiency of the production line.

[0038] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions of the embodiments of the present application will be clearly and completely described below in conjunction with the drawings of the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments.

Thus, an object defined as "first," "second," etc. may explicitly or implicitly include one or more of such objects.

[0040] The following combination Figure 1A display screen testing system is described, which is a display screen aging testing system capable of performing aging test on display screens. The system includes a computer device 10, a plurality of trolleys 30 and an aging testing furnace 20. The computer device 10 can be a PC, which is configured to provide dot screen data. Each trolley 30 is provided with a plurality of pattern generators 31, which are configured to acquire the dot screen data from the computer device 10 and cause the display screen under test to display a test picture based on the acquired dot screen data. The aging testing furnace 20 has a plurality of compartments 21 for accommodating the trolleys 30. Each trolley 30 is capable of moving into and out of any one of the plurality of compartments 21. In order to facilitate the movement of the trolleys 30, walking casters can be arranged at the bottom of the trolleys 30.

[0041] In addition, the system further includes a plurality of first identifiers 32 and a plurality of second identifiers 22. The plurality of first identifiers 32 are arranged on the plurality of trolleys 30 one-to-one, so as to mark the identities of the plurality of trolleys 30 by means of the first identification information possessed by the first identifiers 32. The plurality of second identifiers 22 are arranged in the plurality of compartments 21 one-to-one, so as to mark the identities of the plurality of compartments 21 by means of the second identification information possessed by the second identifiers 22. The first identifiers 32 are operatively connected to each of the second identifiers 22 and the computer device 10, so as to acquire the corresponding second identification information from the second identifiers 22 and transmit the second identification information and the corresponding first identification information to the computer device 10.

[0042] Specifically, the first identifiers 32 can generate the first identification information, and the second identifiers 22 can generate the second identification information. Since each first identifier 32 is arranged on each trolley 30 one-to-one, and each second identifier 22 is arranged in each compartment 21 one-to-one, as long as the first identification information generated by each first identifier 32 is different from each other, and the second identification information generated by each second identifier 22 is different from each other, the computer device 10 can determine which trolley 30 is arranged in which compartment 21 according to the first identification information and the second identification information acquired from the first identifiers 32, so as to guide the computer device 10 to perform subsequent operations according to the information, such as establishing a communication link with the corresponding pattern generator 31 to send dot screen data to the pattern generator 31.

[0043] In the embodiment, when the trolley 30 is moved into the target compartment 21, the first identifier 32 on the trolley 30 can be operatively connected to the computer device 10 and the second identifier 22 in the compartment 21, so as to acquire the corresponding second identification information from the second identifier 22 and transmit the second identification information and the corresponding first identification information to the computer device 10.

[0044] In the present embodiment, all the pattern generators 31 on the plurality of trolleys 30 have mutually different preset IP addresses, so that the computer device 10 has the ability to communicate with and send the point screen data to all the pattern generators 31 simultaneously. For each of the plurality of trolleys 30, the first identification information of the first identifier 32 thereon and the preset IP address of each pattern generator 31 thereon are pre-stored in the computer device 10 in association with each other. In this way, when the computer device 10 acquires the first identification information of the first identifier 32 on the trolley 30, the IP addresses of the pattern generators 31 on the current trolley 30 can be determined based on the association, so that the point screen data is sent to the pattern generators 31 on the trolley 30 based on the IP addresses.

[0045] In the present embodiment, the computer device 10 can include a display operable to display the aforementioned first identification information and second identification information. In operation, the job personnel can observe the first identification information and second identification information displayed by the computer device 10 through the display. In one example, the display of the computer device 10 displays that the current trolley 30 is No. 2 trolley 30 and is located in No. 1 cabin 21, and No. 1 trolley 30 is located in No. 2 cabin 21, based on which the job personnel can operate the computer device 10 as needed to cause the computer device 10 to send the point screen data to the pattern generators 31 on the No. 2 trolley 30 (or the pattern generators 31 on the No. 1 trolley 30) to cause the display screen under test in the No. 1 cabin 21 to display the test picture. In the aforementioned example, when the job personnel operates the computer device 10 as needed to cause the computer device 10 to send the point screen data to the pattern generators 31 on the No. 2 trolley 30 to cause the display screen under test in the No. 1 cabin 21 to display the test picture, the computer device 10 also automatically sends instructions to other related electrical equipment (such as lighting devices) in the No. 1 cabin 21 to prepare the other related electrical equipment in the No. 1 cabin 21 for the burn-in test of the display screen in the cabin 21.

[0046] In some embodiments, the display is operable to display a human-computer interaction interface having a plurality of operation controls corresponding to the plurality of cabins 21 respectively. When the job personnel desires to perform the burn-in test on the display screen in a cabin 21, the operation control corresponding to the cabin 21 can be operated, whereby the computer device 10 sends the point screen data to the pattern generators 31 on the trolley 30 in the cabin 21 and controls the related electrical equipment in the cabin 21 to prepare for the burn-in test.

[0047] In some embodiments, the first identifier 32 is a serial device networking server, which has a second preset IP address, and the second preset IP address constitutes the aforementioned first identification information. The serial device networking server can be purchased from Shandong Yihua Network Co., Ltd., and its model can be USR-TCP232-302 (commonly known as "Yihua USR-TCP232-302 module"), USR-TCP232-304, USR-TCP232-306, USR-TCP232-410s, or USR-TCP232-test.

[0048] The IP address of the serial device networking server, i.e., the second preset IP address, can be pre-configured and fixed by the operator. When the operator moves a certain trolley 30 into the corresponding cabin 21, the power supply is connected to the serial device networking server and the pattern generator 31 on the trolley 30. After the serial device networking server is powered on and works, it can create a TCP / IP network connection to try to access the service started by the computer device 10, and can obtain the second identification information representing the identity of the cabin 21 from the second identifier 22 of the cabin 21. After the listening port of the computer device 10 obtains the communication information of the serial device networking server that currently requests to connect, the computer device 10 establishes communication with the serial device networking server, parses the IP address of the serial device networking server, i.e., the aforementioned second preset IP address, determines the identity of the trolley 30 according to the second preset IP address, further determines the IP addresses of the pattern generators 31 in the cabin 21 based on the association relationship between the first identification information and the second preset IP address, and then sends the screen point data to the pattern generators 31. In this process, the serial device networking server as the first identifier 32 sends the second identification information of the second identifier 22 to the computer device 10, so that the computer device 10 knows the cabin 21 where the trolley 30 is located, and performs relevant control on the cabin 21.

[0049] In some embodiments, the second identifier 22 is a relay with dial function, and the dial value constitutes the aforementioned second identification information. Such relays can be purchased from Beijing Juying Aerospace Electronics Co., Ltd., and the model can be DAM0404D or DAM0606. Exemplarily, four second identifiers 22 (DAM0404D relays) in the four chambers 21 of the aging test furnace 20 can be dialled to 1, 2, 3 and 4 respectively, and the dial values 1 to 4 correspond to the aforementioned second identification information of the four chambers 21 respectively. When the computer device 10 obtains the first identification information 192.168.5.230 from a certain first identifier 32, and the second identification information is 3, it indicates that the trolley 30 with the IP address 192.168.5.230 is in the third chamber 21. In some embodiments, other electrical devices are arranged in the chamber 21 and electrically connected to the relay, and the power on / off of the other electrical devices is controlled by the relay.
