[0040] Next, in combination with the accompanying drawings, based on the above optical engine test system, some embodiments of the present application will be described in detail. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.
[0041] Please refer to Figure 2 , Figure 2 which is a schematic flowchart of an optical engine test method provided by an embodiment of the present application.
[0042] As shown Figure 2 in the figure, the optical engine test method specifically includes steps S101 to S103.
[0043] S101. Based on the optical engine type of the current optical engine, determine the target interface unit corresponding to the current optical engine in the field programmable gate array (FPGA) module;
[0044] In this embodiment, the optical engine types include the type corresponding to the serial peripheral interface (SPI) interface (i.e., Serial Peripheral Interface), the type corresponding to the command mode of the high-speed serial interface between the processor and the display module (i.e., MIPI DSI Command Mode), and the type corresponding to the video mode (i.e., MIPI DSI Video Mode). The interface units corresponding to each type of optical engine are predefined in the interface control module of the FPGA module. When testing the current optical engine, obtain the optical engine type of the current optical engine. Then, among the predefined interface units in the interface control module of the FPGA module, determine the interface unit corresponding to the optical engine type of the current optical engine, and use this interface unit as the target interface unit.
[0045] In one embodiment, each optical engine type is numbered in the host computer in advance. For example, the optical engine type corresponding to the SPI interface is numbered 0, the optical engine type corresponding to the MIPI DSI Command Mode is numbered 1, the optical engine type corresponding to the MIPI DSI Video Mode is numbered 2, etc. Based on the start command of the test process issued by the host computer, the parameter parsing unit in the FPGA module parses the data sent by the host computer. Among them, the sent data includes test data and system commands; the system commands include start commands and stop commands; the test data includes a test picture set, the optical engine interface type, and display parameters; the display parameters include display timing and display pixel size. When the start command is parsed, the interface control module in the FPGA module determines the target interface unit according to the optical engine type of the current optical engine among the interface units corresponding to each optical engine type.
[0046] S102. Based on the target interface unit, send test data to the current optical engine so that the current optical engine performs image display based on the test data;
[0047] In this embodiment, the test data includes test pictures and the display timing of the optical engine to be tested. Among them, the test pictures can be a test picture set, and the test picture set includes specific pictures, such as all-white, all-black, all-red, all-green, all-blue pictures or pictures of grids of various colors, etc. As Figure 3As shown, the display timing includes display line pixels (i.e., horizontal display pixels), column pixels (i.e., vertical display pixels), vertical back porch pixels VBP, vertical front porch pixels VFP, horizontal back porch pixels HBP, horizontal front porch pixels FBP, vertical sync pulse width VSYNC, horizontal sync pulse width HSYNS, and the blanking area (i.e., the gray area in the figure) other than the display active area in the figure, etc. After determining the target interface unit in the interface control module, the target interface unit sends test data to the current optical engine. Thus, the current optical engine displays the corresponding image according to the test data for optical engine testing.
[0048] In one embodiment, when the optical engine to be tested can generate display timing according to its own screen parameters internally, only the test picture is obtained as the test data; if the optical engine to be tested cannot generate display timing according to its own screen parameters, the test picture and the display timing corresponding to the optical engine to be tested (i.e., the screen of the optical engine to be tested) are obtained as the test data. Among them, the screen parameters include resolution, refresh rate (i.e., the number of times the electron beam scans the image on the screen within 1 s), color gamut, color accuracy, and color depth, etc.
[0049] In another embodiment, the test picture and its corresponding display timing can be defaultly obtained as the test data, that is, the target interface unit sends the test data including the test picture and its corresponding display timing to the current optical engine. If the current optical engine can generate display timing according to the test picture internally, the image is output with the display timing generated internally by the current optical engine.
[0050] S103. Test the current optical engine based on the display result of the current optical engine.
[0051] In this embodiment, in order to perform optical engine testing on the current optical engine, it is necessary to make the current optical engine output a specific image. Then, the display parameters such as the pixel size, color, and color temperature of the displayed image are detected. If there are no abnormalities in the parameters to be detected, it means that the current optical engine passes the test; otherwise, it means that the current optical engine test fails.
[0052] Specifically, after the target interface unit outputs the test data to the current optical engine, the display result of the current optical engine for the image corresponding to the test data is obtained, and the test of the current optical engine is completed according to the display result. If the display result is that all display parameters are within the preset range, it means that the current optical engine passes the test; otherwise, it means that the current optical engine test fails.
[0053] This embodiment provides an optical engine testing method. Based on the optical engine type of the current optical engine, a target interface unit corresponding to the current optical engine is determined in a field programmable gate array (FPGA) module; based on the target interface unit, test data is sent to the current optical engine so that the current optical engine performs image display based on the test data; based on the display result of the current optical engine, the current optical engine is tested. In the above manner, this application provides interface units corresponding to multiple types of optical engines based on the FPGA module, and then determines the target interface unit corresponding to the current optical engine according to the optical engine type of the current optical engine to be tested. And the test data is sent to the current optical engine through the target interface unit to implement the optical engine test of the current optical engine. Thus, based on the multiple interface units provided by the FPGA module, an optical engine testing device can support multiple types of optical engine interfaces, and multiple types of optical engines can be tested by one optical engine testing device, thereby improving the optical engine testing efficiency.
[0054] Please refer to Figure 4 , Figure 4 which is a schematic flowchart of an optical engine testing method provided by an embodiment of this application.
[0055] As Figure 4 shown, before step S102, this optical engine testing method further includes:
[0056] S110, determining the test data based on the optical engine type of the current optical engine.
[0057] In one embodiment, since the internal part of some optical engines can generate a display timing, therefore, the host computer or the FPGA module does not need to further send a display timing to this type of optical engine. Thus, according to the two types of optical engines that can generate a display timing and those that cannot, the test data is classified. Specifically, the optical engine type and its corresponding test data are set in advance. For the optical engine that can generate a display timing according to the test picture, the corresponding test data is the test picture, and for the optical engine that cannot generate a display timing according to the test picture, the corresponding test data is the test picture and the display timing corresponding to this optical engine type.
[0058] In one embodiment, the display timing control module in the FPGA module pre-generates the display timing corresponding to each type of optical engine according to the display timing requirements of each type of optical engine, such as the display line pixel size requirement, column pixel requirement, or blanking area requirement, etc.
[0059] Further, the S110 specifically includes:
[0060] When the optical engine type of the current optical engine is the first type, obtaining a test picture as the test data, where the optical engine of the first type is an optical engine that can generate a display timing.
[0061] When the type of the current optical engine is the second type, obtain a test picture and the display timing corresponding to the current optical engine as the test data, where the optical engine of the second type is an optical engine that cannot generate display timing.
[0062] In this embodiment, the type of the optical engine includes a first type, that is, an optical engine type in which the display timing can be generated according to its own display screen parameters inside the optical engine, such as the type corresponding to MIPI DSI Command Mode and the type corresponding to SPI, and a second type, that is, an optical engine type in which the display timing cannot be generated according to its own display screen inside the optical engine, such as the type corresponding to MIPI DSI Video Mode.
[0063] When the display timing can be generated according to the test picture inside the optical engine of the current optical engine, that is, the type of the current optical engine is the first type, only obtain the test picture as the test data;
[0064] If the display timing cannot be generated inside the optical engine of the current optical engine, that is, the type of the current optical engine is the second type, then obtain the test picture and the display timing corresponding to the optical engine to be tested as the test data.
[0065] In the above manner, determine the test data according to the type of the optical engine, which can simplify the test data and further improve the test efficiency of the optical engine.
[0066] Further, before the step S102, it further includes:
[0067] Obtain the test data from an external memory and store the test data in an internal storage module in the FPGA module.
[0068] In this embodiment, the host computer (that is, a computer that can directly issue control commands, such as a control terminal such as a computer or a tablet) sends the test data (that is, the test picture) to the FPGA module through a communication interface (such as a common serial port or USB). When the parameter parsing module in the FPGA module parses that the data sent by the host computer is a test picture, write the test picture into the external memory. Then store the test picture in the external memory in the internal storage module in the FPGA module.
[0069] In one embodiment, the test pictures with a usage frequency exceeding a preset value can be stored from the external memory to the internal storage module in the FPGA module to reduce the sending time of the test data and further improve the test efficiency of the optical engine.
[0070] In another embodiment, when it is parsed that the data sent by the host computer is a start command, read the test picture from the external memory (the external memory is a power-failure non-volatile device such as Flash) according to the start instruction and cache it in the internal storage module.
[0071] In more embodiments, after the host computer sends a test picture to the external memory once, according to a preset period, it is determined whether the test picture set in the host computer is updated. If it is updated, the host computer is made to re-send the updated test picture set; if it is not updated, there is no need for the host computer to re-send the picture set in subsequent tests.
[0072] Further, sending the test data to the current optical engine based on the target interface unit includes:
[0073] Based on the target interface unit, sending the test picture to the current optical engine according to the display timing.
[0074] In this embodiment, as Figure 5 shown, the test data in the internal storage module is output to the target interface unit according to the display timing corresponding to the current optical engine. The target interface unit then outputs the test picture to the current optical engine according to the display timing.
[0075] Further, before the step S101, it further includes:
[0076] Based on the number of optical engines to be tested, determine the number of interface units, and instantiate the interface units corresponding to the number of interface units.
[0077] In this embodiment, the interface control module can pre-instantiate multiple interface units according to the size of the test resources and the requirements for the number of optical engines to be tested. For example, instantiate 4 DSI Video Mode interfaces or SPI interfaces. Among them, instantiating an interface unit is the process of creating an object interface with a class in object-oriented programming. One interface can only send test data to one optical engine at the same time. By controlling multiple interface units to send test data to multiple optical engines at the same time, not only can a test device test multiple types of optical engines, but also multiple optical engines can be tested simultaneously, further improving the optical engine test efficiency.
