Description

Technical Field

[0001] The present invention relates to the technical field of display modules, and particularly to a method for a module factory to enable a client to quickly identify a module supplier. Background Art

[0002] In the current liquid crystal module industry, there are often multiple different display module suppliers for the same project of a client. For the finished modules provided by different module suppliers for the same project, it is often difficult to distinguish from which module supplier they come from in terms of appearance. Only the FPC silk screen can be used for differentiation, but each module factory has its own specification for the silk screen naming of the FPC, resulting in great difficulty for the client to distinguish solely through the silk screen. Moreover, the method of identifying the module supplier only through the FPC silk screen not only has low timeliness but also may lead to misjudgment, so that the wrong module is used, resulting in the outflow of defective products with wrong screens installed. Further, after the end customer installs the machine, problems such as the whole machine flashing the screen, not displaying, abnormal current, and high power consumption may occur, leading to complaints and fines from the end customer. Therefore, the existing technology has defects and needs to be improved. Summary of the Invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a technology combining software and hardware to accurately identify the supplier of a module from both software and hardware aspects, which can well avoid the problems of low accuracy, low efficiency, high cost, and easy misjudgment in manually judging the module supplier by identifying the silk screen on the module FPC, thereby preventing the outflow of defective products with wrong screens installed to the end customer and avoiding potential losses and risks in the follow-up. Specifically, a method for a module factory to enable a client to quickly identify a module supplier is provided.

[0004] The technical solution of the present invention is as follows: A method for a module factory to enable a client to quickly identify a module supplier according to the present invention includes the following steps: Step 1: Obtain the module supplier through the first method and the second method respectively; Step 2: Compare the results of the module suppliers obtained by the first method and the second method; Step 3: If the comparison result in Step 2 is the same, output the module supplier.

[0005] Wherein: The first method is: Set a voltage detection circuit on the module FPC; Determine the module supplier by detecting and comparing the voltage of the voltage detection circuit; The second method is: Determine the module supplier by identifying and comparing the address and value of the register of the module.

[0006] Further, in the first method, the voltage detection circuit includes a first resistor and a second resistor. One end of the first resistor is electrically connected to the power supply terminal, and the other end of the first resistor is electrically connected to the detection terminal and one end of the second resistor respectively. The other end of the second resistor is grounded.

[0007] Further, in the voltage detection circuit, a voltage division structure one and / or a voltage division structure two and / or a voltage division structure three are included; wherein,

[0008] The voltage division structure one is: the resistance value of the first resistor is not 0, and the resistance value of the second resistor is 0;

[0009] The voltage division structure two is: the resistance value of the first resistor is 0, and the resistance value of the second resistor is not 0;

[0010] The voltage division structure three is: the resistance values of the first resistor and the second resistor are both not 0.

[0011] Further, in step 3, if the comparison result in step 2 is different, then step 4 is entered; step 4 is: perform step 1 and step 2 again. If the comparison results are the same, then the module supplier is output.

[0012] Further, in step 4, if the comparison results are still different, then the result of failed recognition is output.

[0013] Adopting the above solution, the beneficial effects of the present invention are as follows: Through the combination of software and hardware for detection and comparison, this solution compares with the set value from two dimensions of hardware and software, and then quickly and accurately identifies which supplier the module comes from, thus avoiding the inaccuracy and low efficiency caused by manually judging the module supplier from the module FPC silk screen, avoiding the risk that may be caused by delivering the product with the wrong module installed to the end customer for installation, greatly reducing the potential hazards, and reducing the risks and economic losses that may cause the whole machine to have display defects or even be scrapped. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is the circuit diagram of the voltage detection circuit of an embodiment of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The present invention will be described in detail below in conjunction with the drawings and specific embodiments.

[0016] Please refer to Figure 1, in this embodiment, the present invention provides a method for a module factory to enable a client to quickly identify a module supplier, including the following steps: Step 1: Obtain the module supplier through the first method and the second method respectively. Among them: The first method is: Set a voltage detection circuit on the module FPC; Determine the module supplier by detecting the voltage of the voltage detection circuit and comparing it with the pre-stored data. Among the pre-stored voltage values, specific voltage values correspond to specific module suppliers. When the detected voltage value matches the pre-stored data, it can be determined as the product of this module supplier. The second method is: Determine the module supplier by identifying and comparing the address and value of the register of the module. This method reads the corresponding address and value of the register after the module is powered on. The system can judge which module supplier the corresponding address and corresponding value come from according to the read address and value and the pre-stored corresponding chips, and can also accurately and quickly identify the module supplier.

[0017] Step 2: Compare the module supplier results obtained by the first method and the second method. Step 3: If the comparison results in Step 2 are the same, output the module supplier. For example, if the module suppliers obtained by the first method and the second method are A, then the results are the same at this time, and the module supplier A can be output.

[0018] Further, in the first method, the voltage detection circuit includes a first resistor R1 and a second resistor R2. One end of the first resistor R1 is electrically connected to the power supply terminal (IOVCC terminal in this embodiment, with a voltage of 1.8V), and the other end of the first resistor R1 is electrically connected to the detection terminal (LCD_ID terminal in this embodiment) and one end of the second resistor R2 respectively. The other end of the second resistor R2 is grounded.

[0019] Further, in the voltage detection circuit, it includes a voltage division structure one and / or a voltage division structure two and / or a voltage division structure three; among them,

[0020] The voltage division structure one is: The resistance value of the first resistor R1 is not 0, and the resistance value of the second resistor R2 is 0. At this time, the voltage detected at the LCD_ID terminal is the voltage of IOVCC (1.8V).

[0021] The voltage division structure two is: The resistance value of the first resistor R1 is 0, and the resistance value of the second resistor R2 is not 0. At this time, the voltage detected at the LCD_ID terminal is 0V.

[0022] The voltage division structure three is: The resistance values of the first resistor R1 and the second resistor R2 are both not 0. At this time, the voltage detected at the LCD_ID terminal = IOVCC / (R1 + R2)*R2.

[0023] Through the design of the hardware ID circuit, after the module is powered on, the LCD_ID signal detection pin will read the corresponding voltage value. The module factory can set the corresponding voltage value for a specific voltage value by the client. Furthermore, the module factory can match the voltage division resistors R1 and R2 of the corresponding hardware ID circuit in the FPC to obtain the special voltage value desired by the customer, so that when the module is powered on, the system can quickly and accurately determine the module supplier by reading the LCD_ID voltage value.

[0024] Further, in the step 3, if the comparison result in the step 2 is different, then enter the step 4; the step 4 is: perform the step 1 and step 2 again. If the comparison results are the same, then output the module supplier.

[0025] Further, in the step 4, if the comparison results are still different, then output the result of failed recognition.

[0026] In summary, the beneficial effects of the present invention are as follows: By means of combining software and hardware for detection and comparison, comparing with the set value from two dimensions of hardware and software, and then quickly and accurately identifying which supplier the module comes from, thus avoiding the inaccuracy and low efficiency caused by manually judging the module supplier from the module FPC silk screen, avoiding the risk that the product with the wrong module installed is given to the end customer for installation, greatly reducing the potential hazards, and reducing the risk and economic loss that may cause the whole machine to have display defects or even be scrapped.

[0027] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
