specific embodiment

In order to make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, each embodiment of the present invention will be described in detail below with reference to the accompanying drawings. However, those of ordinary skill in the art can appreciate that, in various embodiments of the present invention, many technical details are provided for the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solutions claimed in the present application can be realized. The following divisions of the various embodiments are for the convenience of description, and should not constitute any limitation on the specific implementation of the present invention, and the various embodiments may be combined with each other and referred to each other on the premise of not contradicting each other.

The first embodiment of the present invention relates to a detection method, and the specific process is shown in Figure 1, which includes the following steps:

Step 101, detecting whether the display driver is abnormal.

Specifically, the detection system corresponding to the detection method in this embodiment includes a display driver and a microcontroller, wherein the execution subject of this embodiment is the display driver.

In practical applications, the display driver can periodically detect whether it is abnormal, and at the same time, each detection will send a feedback signal to the microcontroller; when the display driver detects that it is normal, the display driver sends a signal to the microcontroller indicating that it is normal When the display driver detects that it is abnormal, the display driver sends a feedback signal representing the abnormality to the microcontroller.

Step 102 , if the display driver is abnormal, send a feedback signal representing the abnormality to the microcontroller connected to the display driver, so that the microcontroller can repair the display driver according to the feedback signal representing the abnormality.

Specifically, when the display driver detects that it is abnormal, the display driver will send a feedback signal representing the abnormality to the microcontroller. After the microcontroller receives the feedback signal representing the abnormality, that is, the microcontroller receives the abnormal operation of the display driver. signal, which causes the microcontroller to initiate the repair procedure.

In practical applications, the display driver will periodically send feedback signals to the microcontroller; when the display driver detects that it is normal, the display driver will send a normal feedback signal to the microcontroller, and the microcontroller will receive a normal feedback signal. After the feedback signal, the repair program will not be started; when the display driver detects that it is abnormal, the display driver will change the signal strength of the feedback signal, that is, the feedback signal is abnormal at this time, and send the abnormal feedback signal to the microcontroller, so that The microcontroller can determine whether the feedback signal is abnormal according to the signal strength of the feedback signal. After the microcontroller determines that the received feedback information is a feedback signal representing an abnormality, the microcontroller starts a repair program to repair the display driver.

The conventional detection method used in the prior art is to obtain the state parameters of the display driver after the detection command sent by the microcontroller to the display driver, and the microcontroller determines whether the parameters of the display driver are abnormal, and when the microcontroller determines the state of the display driver When the parameter is abnormal, it means that the display driver is abnormal. After the status parameters of the display driver are transmitted to the microcontroller, the microcontroller also needs to determine whether the display driver is abnormal in order to obtain the abnormal information of the display driver, which will cause the microcontroller to obtain the abnormal information of the display driver at a slower speed. . Therefore, in this embodiment, the display driver detects whether it has an abnormality by itself. After the display driver detects that it is abnormal, it sends a feedback signal representing the abnormality to the microcontroller, so that the microcontroller can directly obtain the display driver. Abnormal information, compared with the prior art, the microcontroller can acquire the abnormal information of the display driver in a more timely manner, and repair the display driver in time.

In one example, detecting whether the display driver is abnormal includes: detecting a value of a status indicator of the display driver, and determining whether the display driver is abnormal according to the value of the status indicator; wherein, the status indicator is when the status of the display driver is normal or abnormal. value is different. Specifically, there is a status mark inside the display driver, and the value of the status mark can be determined according to the operating state of the display driver. When the display driver is abnormal, the value of the status mark will be different from the value of the status mark when it is normal; therefore, In this embodiment, it is judged whether the display driver is abnormal by the value of the status flag of the display driver, which can reduce the pressure of the judgment of the display driver.

In one example, the value of the status flag is the value of a register within the display driver. Specifically, there is a register in the display driver, and the value of the register will change according to the operating state of the display driver. For example, when the operating state of the display driver is normal, the value of the register is a fixed value A, when the operating state of the display driver is When it is abnormal, the value of the register is an indeterminate value B, where A is not equal to B, that is to say, when the value of the current register is different from the fixed value A, it means that the running state of the display driver is abnormal, and the display driver will Send a feedback signal that characterizes the anomaly to the microcontroller. In other embodiments, it may be determined whether the display driver is abnormal through the values of other status identifiers of the display driver.

A second embodiment of the present invention relates to a detection method. The second embodiment is roughly the same as the first embodiment, and the main difference is that: in the second embodiment of the present invention, sending a feedback signal representing an abnormality to a microcontroller includes: sending a feedback signal representing an abnormality to the microcontroller through the second channel feedback signal.

The personnel know that the signal sent through MIPI will be truncated by the image processing chip, so that the detection command sent by the microcontroller to the display driver will be truncated by the image processing chip. In this application scenario, the use of conventional detection methods cannot be effective Check the monitor.

Therefore, in this embodiment, the display driver 202 detects its own abnormality. When the display driver 202 detects that it is abnormal, it can directly send a feedback signal representing the abnormality to the microcontroller 201 through the second channel, so that the abnormality The feedback signal can be detected without passing through the image processing chip 203 . In addition, after the microcontroller 201 receives the abnormal feedback signal, it repairs the display driver 202, and the repair process does not need to be sent through MIPI. Therefore, the repair process will not be blocked by the image processing chip 203, so that the detection method of the present application is not blocked. The interference of the image processing chip 203 to the detection process of the display driver 202 is eliminated.
