Description

Technical Field

[0001] The present invention relates to the technical field of display devices, and in particular to a chip burning device and method for an in-vehicle display unit, and an in-vehicle display device. Background Art

[0002] There are currently two ways to adjust and program the parameters of the Touch and Display Driver Integration (TDDI) IC for automotive displays. One is to program the TDDI IC in the CFOG state (a specific stage or process in the manufacturing process of the LCD module that binds the TDDI IC to the LCD module). The video signal generator directly programs the TDDI IC through the SPI interface led out by the TDDI IC. The other is to design an SPI interface or observation point on the driver board of the display, or to design an I 2 C interface or measuring point, through which the video signal generator is connected for burning.

[0003] If OTP is performed in CFOG mode, some products require aging of the entire structural components, which can affect LCD characteristics and cause display problems. Therefore, OTP is performed after aging. This requires disassembling the structural components and programming via SPI communication with the TDDI IC. This back-and-forth disassembly of the structural components can easily damage the product and cause losses. Using a probe to program at the SPI test point on the PCB has a high failure rate, requiring very strict probe touch accuracy and the largest possible test point, which also compresses the PCB area. Summary of the Invention

[0022] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0023] It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0024] Figure 1 A schematic diagram of the structure of a chip burning device for a vehicle-mounted display device provided by an embodiment of the present invention, referring to Figure 1The vehicle-mounted display system 100 includes a display panel 110 and a driver chip 120. The driver chip 120 is used to provide a display signal for the display panel 110. The chip burning device 200 includes a control chip 210, a first communication interface 220, and a microprocessor 230 and a second communication interface 240 integrated in the vehicle-mounted display system 100. The driver chip 120 and the second communication interface 240 are both connected to the microprocessor 230, the control chip 210 is connected to the first communication interface 220, and the first communication interface 220 and the second communication interface 240 are communicatively connected.

[0025] It should be noted that to improve the display consistency of the display panel 110, the industry has proposed a one-time programmable (OTP) burning solution for the drive voltage. By burning the drive voltage adjustment value into the driver chip 120 via OTP, the output voltage value of the supporting driver chip 120 can be adjusted to match the drive voltage of the display panel 110 and meet various customer color requirements. Typically, the driver code containing the debugging data of the driver chip 120 is written into the driver chip 120. When the display panel 110 starts operating, the driver code is activated to drive the display panel 110. When the driver code needs to be modified, the updated driver code is written into the driver chip 120. In the early stages of screen lighting, the driver code needs to be frequently modified to ensure consistency. By adjusting these codes in the driver chip 120, gamma correction and shift register (VSR) timing can be performed to improve the display effect. Once the delivery meets the customer's expectations, these codes are not changed (OTP curing operation). This is different from other codes in the driver chip 120 in that some basic function items in the driver chip 120 are factory default settings and do not need to be changed according to different project requirements of the display panel 110. The driver code needs to be debugged, which is related to the display panel 110 required by different projects.

[0026] The control chip 210 may include a system-on-chip (SoC). It should be noted that an SoC is a dedicated integrated circuit that contains all the contents of a complete system and embedded software. An SoC typically integrates a microprocessor, analog IP core, digital IP core, and memory (or an off-chip memory control interface) on a single chip to form a miniature system. SoC technology is highly integrated and firmware-based. By combining multiple integrated circuits with specific functions on a single chip, a complete hardware system and the embedded software it carries are formed. This design not only saves space but also improves system reliability and performance.

[0027] The embodiment of the present invention can use the control chip 210 to transmit the debugging data of the driver chip 120 to the driver chip 120 for burning through the first communication interface 220 and the second communication interface 240 and microprocessor 230 integrated in the vehicle-mounted display unit 100. The burning efficiency is high, and the burning can be completed without disassembling the structural parts of the vehicle-mounted display unit 100, which can avoid damage to the product caused by disassembling the structural parts.

[0028] Optionally, based on the above embodiment, the control chip 210 transmits the debugging data of the driver chip 120 to the microprocessor 230 through the first communication interface 220 and the second communication interface 240. The microprocessor 230 converts the communication protocol and transmits the debugging data to the driver chip 120 for burning.

[0029] It is understandable that different driver chips 120 may support different communication protocols. To ensure that the programming process can proceed smoothly, it is necessary to select a suitable communication protocol to convert the debugging data of the driver chip 120 according to the specific model and interface type of the chip.

[0030] In the embodiment of the present invention, during the programming process, the microprocessor 230 converts the communication protocol and transmits the debugging data to the driver chip 120 for programming, which can improve the efficiency and accuracy of data transmission.

[0031] Figure 2 A schematic structural diagram of another chip burning device for a vehicle-mounted display device according to an embodiment of the present invention. Optionally, based on the above embodiment, reference is made to Figure 2 The first communication interface 220 and the second communication interface 240 both include controller area network (CAN) modules 201 and 202 . The control chip 210 is used to convert the signal containing debugging data into a CAN signal and transmit it to the first communication interface 220 . The CAN signal is transmitted to the microprocessor 230 through the second communication interface 240 .

[0032] It should be noted that the Controller Area Network (CAN) modules 201 and 202 are serial communication network modules used to implement distributed real-time control. CAN signals are a serial communication protocol used in automotive and industrial automation. Any node on the network can actively send data to any other node at any time, providing flexible communication. They offer excellent real-time performance and are suitable for systems requiring fast response times. They also have a reliable error detection mechanism, resulting in an extremely low data error rate and automatic disconnection from the bus in the event of a serious error.

[0033] The embodiment of the present invention uses controller area network CAN modules 201 and 202 to realize communication between the control chip 210 and the microprocessor 230, and can convert the signal containing debugging data into a CAN signal containing debugging data and quickly transmit it to the microprocessor 230 with a low error rate.

[0034] Optionally, based on the above embodiment, the microprocessor 230 is used to convert the CAN signal into a serial peripheral interface SPI signal or an integrated circuit bus I 2 C signal is then transmitted to the driver chip 120 .

[0035] It is understandable that when the driver chip 120 supports SPI communication, the microprocessor 230 converts the CAN signal containing the debugging data into a serial peripheral interface SPI signal containing the debugging data and transmits it to the driver chip 120. 2 During C communication, the microprocessor 230 converts the CAN signal containing the debugging data into an integrated circuit bus IC signal containing the debugging data. 2 C signal is then transmitted to the driver chip 120 .

[0036] The embodiment of the present invention uses the microprocessor 230 to transmit debugging data, and can convert the CAN signal containing the debugging data into a signal type supported by the driver chip 120 and transmit it to the driver chip 120, thereby improving the efficiency and accuracy of data transmission.

[0037] Figure 3 A schematic structural diagram of another chip burning device for a vehicle-mounted display device according to an embodiment of the present invention. Optionally, in the above Figure 1 Based on the corresponding embodiments, refer to Figure 3 The first communication interface 220 includes a serializer 203, the second communication interface 240 includes a deserializer 204, and the control chip 210 is used to convert the signal containing debugging data into a video parallel signal and transmit it to the first communication interface 220. The video parallel signal is converted into a video serial signal through the first communication interface 220, and the video serial signal is transmitted to the microprocessor 230 through the second communication interface 240.

[0038] It should be noted that the primary function of serializer 203 is to convert parallel data into serial data, facilitating data transmission and communication within limited transmission bandwidth. Serializer 203 also acts as a demodulator (demultiplexer), restoring serial data to its original parallel form. Deserializer 204 is responsible for converting high-speed serial signals back into low-speed parallel signals. Deserializer 204 can be flexibly configured based on specific application requirements, supporting a variety of data widths and encoding methods.

[0039] In an embodiment of the present invention, the serializer 203 and deserializer 204 are used to transmit a video signal containing debugging data, enabling a higher data transmission rate within a limited transmission bandwidth. Because serial communication uses differential signal transmission, it has stronger anti-interference capabilities. The serializer 203 and deserializer 204 support a variety of different data widths and encoding methods, allowing for flexible configuration based on specific application requirements. Furthermore, when using transmission media such as optical fiber or twisted pair cables, serial communication can be adapted for long-distance transmission. Through appropriate coding and modulation techniques, long-distance data transmission can be achieved while maintaining a low bit error rate.

[0040] Figure 4 A schematic structural diagram of another chip burning device for a vehicle-mounted display device according to an embodiment of the present invention. Optionally, in the above Figure 3 Based on the corresponding embodiments, refer to Figure 4 The video parallel signal is converted into a video serial signal by the serializer 203 , and the video serial signal is transmitted to the deserializer 204 via the Gigabit Multimedia Serial Link GMSL or FPD-LINK 250 .

[0041] It should be noted that the Gigabit Multimedia Serial Link (GMSL) or FPD-LINK 250 is a point-to-point video transmission interface used in many automotive applications. It converts multiple parallel data streams (including video, control, and voice data) at the transmitting end into a single serial data stream. At the receiving end, the serial data is then converted back into a parallel video format and low-speed control signals that can be received by the display panel 110 or the control chip 210.

[0042] In the embodiment of the present invention, the control chip 210 converts the signal containing debug data into a video parallel signal containing debug data and transmits it to the serializer 203. The serializer 203 then converts the video parallel signal containing debug data into a video serial signal containing debug data. The video serial signal containing debug data is then converted back into a video parallel signal containing debug data by the deserializer 204 and transmitted to the microprocessor 230. The serializer 203 converts parallel data into serial data, which reduces the number of required transmission channels and device pins, simplifying hardware design and reducing system complexity and cost. The video serial signal is transmitted via the Gigabit Multimedia Serial Link (GMSL) or FPD-LINK 250, enabling a point-to-point video transmission interface with high transmission speeds.

[0043] Optionally, based on the above embodiment, the microprocessor 230 is used to convert the video serial signal into an SPI signal or an I 2 The C signal is transmitted to the driver chip 120 .

[0044] It is understood that the microprocessor 230 of the embodiment of the present invention can convert the video serial signal into an SPI signal or an I2C signal according to the specific model and interface type of the driver chip 120. 2 The C signal is transmitted to the driver chip 120, which can improve the efficiency and accuracy of data transmission.

Figure 6 A schematic structural diagram of another chip burning device for a vehicle-mounted display device according to an embodiment of the present invention. Optionally, based on the above embodiment, reference is made to Figure 5 and Figure 6 The chip burning device 200 also includes a switch module 260 and a video signal generator 270. The first end of the switch module 260 is connected to the driver chip 120, the second end of the switch module 260 is connected to the microprocessor 230, and the third end of the switch module 260 is connected to the video signal generator 270.

[0046] In this embodiment of the present invention, when the first and second terminals of the switch module 260 are closed, the signal provided by the control chip 210 is transmitted to the driver chip 120. When the first and third terminals of the switch module 260 are closed, the signal provided by the video signal generator 270 is transmitted to the driver chip 120.

[0047] It is understood that by providing the switch module 260, when the first and second ends of the switch module 260 are closed, the signal provided by the control chip 210 is transmitted to the driver chip 120, enabling programming of the driver chip 120 while the vehicle-mounted display device 100 is in an online state. When the first and third ends of the switch module 260 are closed, the signal provided by the video signal generator 270 is transmitted to the driver chip 120, enabling programming of the driver chip 120 while the vehicle-mounted display device 100 is in an offline state.

[0048] The solution of the embodiment of the present invention can select different burning methods in different application scenarios, which is more flexible.

[0049] Optionally, based on the above embodiment, continue to refer to Figure 6 When the first and second ends of the switch module 260 are closed, the microprocessor 230 and the driver chip 120 communicate via the SPI bus or I 2 C bus 280 is connected, and the signal provided by the control chip 210 is transmitted via SPI signal or I 2 C signal is transmitted to the driver chip 120. When the first terminal and the third terminal of the switch module 260 are closed, the video signal generator 270 and the driver chip 120 communicate with each other through the SPI bus or I 2C bus 280, the signal provided by the video signal generator 270 is transmitted via SPI signal or I 2 The C signal is transmitted to the driver chip 120 .

[0050] Among them, the SPI bus is used to transmit the serial peripheral interface SPI signal. 2 C bus is used to transmit integrated circuit bus I 2 When the driver chip 120 supports SPI communication, the microprocessor 230 converts the CAN signal containing the debugging data into a serial peripheral device interface SPI signal containing the debugging data and transmits it to the driver chip 120. 2 During C communication, the microprocessor 230 converts the CAN signal containing the debugging data into an integrated circuit bus IC signal containing the debugging data. 2 C signal is then transmitted to the driver chip 120 .

[0051] Optionally, based on the above embodiment, the driver chip 120 includes a touch and display driver integrated chip.

[0052] Among them, the touch and display driver integrated chip can achieve integrated control of touch and display functions by integrating the touch chip and display chip into a single chip.

[0053] In an embodiment of the present invention, the control chip 210 transmits the debugging data of the touch and display driver integrated chip to the touch and display driver integrated chip for burning through the first communication interface 220 and the second communication interface 240 and microprocessor 230 integrated in the vehicle-mounted display device 100. The burning efficiency is high, and the burning can be completed without disassembling the structural parts of the vehicle-mounted display device 100, which can avoid damage to the product caused by disassembling the structural parts.

[0054] Optionally, based on the above embodiment, continue to refer to Figure 6 The control chip 210 and the first communication interface 220 are integrated on the vehicle controller 300 .

[0055] The control chip 210 and the first communication interface 220 of the embodiment of the present invention are integrated on the vehicle controller 300, and can use the existing vehicle-mounted display device to burn the driver chip 120. The burning efficiency is high, and the burning can be completed without disassembling the structural parts of the vehicle-mounted display unit 100, which can avoid damage to the product caused by disassembling the structural parts.

[0056] In summary, during the chip burning process of the vehicle-mounted display system provided by the embodiment of the present invention, the microprocessor converts the communication protocol and transmits the debug data to the driver chip for burning, which can improve the efficiency and accuracy of data transmission. And because the second communication interface and the microprocessor are integrated into the vehicle-mounted display system, burning can be completed without disassembling the structural parts of the vehicle-mounted display system back and forth, which can avoid damage to the product caused by disassembling the structural parts. In addition, the microprocessor 230 converts the communication protocol and transmits the debug data to the driver chip 120 for burning, which can improve the efficiency and accuracy of data transmission. The controller area network CAN modules 201 and 202 are used to realize communication between the control chip 210 and the microprocessor 230, and the signal containing the debug data can be converted into a CAN signal containing the debug data and quickly transmitted to the microprocessor 230 with a low error rate. The microprocessor 230 is used to transmit the debug data, and the CAN signal containing the debug data can be converted into a signal type supported by the driver chip 120 and then transmitted to the driver chip 120, thereby improving the efficiency and accuracy of data transmission. The use of serializer 203 and deserializer 204 to realize the transmission of video signals containing debugging data can achieve a higher data transmission rate under limited transmission bandwidth. Since serial communication uses differential signal transmission, it has stronger anti-interference ability. Serializer 203 and deserializer 204 support a variety of different data widths and encoding methods, and can be flexibly configured according to specific application requirements. And when using transmission media such as optical fiber or twisted pair, serial communication can be suitable for long-distance transmission. Through appropriate coding and modulation technology, long-distance data transmission can be achieved while maintaining a low bit error rate. The serializer 203 converts parallel data into serial data, which can reduce the required transmission channels and device pins, not only simplifying the hardware design, but also reducing the complexity and cost of the system. The video serial signal is transmitted through the Gigabit Multimedia Serial Link GMSL or FPD-LINK 250, which can realize a point-to-point video transmission interface with a fast transmission speed. The microprocessor 230 can convert the video serial signal into an SPI signal or I2C signal according to the specific model and interface type of the driver chip 120. 2 The C signal is transmitted to the driver chip 120, which can improve the efficiency and accuracy of data transmission. By providing a switch module 260 and a video signal generator 270, different programming methods can be selected for different application scenarios, providing greater flexibility. Integrating the control chip 210 and the first communication interface 220 on the vehicle controller 300 allows the driver chip 120 to be programmed using existing on-board display devices.
