In one or more embodiments, the controller 120 can detect the state of the hall switch 130 through an interrupt or I/O.
The hall switch 130 includes an on state and an off state. In one or more embodiments, the controller 120 can cause the in-vehicle display screen 100 to enter a diagnostic mode based on when the hall switch 130 is in the on state. In one or more embodiments, the controller 120 can cause the in-vehicle display screen 100 to enter a diagnostic mode based on when the hall switch 130 is in the off state.
The hall switch 130 may be, for example, a digital hall switch. Preferably, the hall switch 130 is a bipolar hall switch. The bipolar hall switch is triggered to turn on by one pole (e.g., the S pole) of the magnetic field and remains on until it is triggered to turn off by the other pole (e.g., the N pole) of the magnetic field.
In one or more embodiments, the plurality of display modules 111 includes at least one touch display module. When the touch display screen module senses a predetermined gesture, the controller 120 causes the in-vehicle display screen 100 to enter a diagnostic mode. The predetermined gesture is, for example, ten fingers touching the touch display screen module simultaneously for ten seconds, one finger drawing five circles on the touch display screen, and the like.
In one or more embodiments, the controller 120 can display the diagnostic information by superimposing text on the video stream. For example, diagnostic information text to be displayed is superimposed on the video stream by the image enhancement module 113. It is understood that the controller 120 can also directly superimpose the diagnostic information text to be displayed onto the video stream without going through the image enhancement module 113. The diagnostic information may include one or more of environmental information, display module information, video information, touch information, and general information. The environmental information may include, for example, one or more of a backlight LED (Illumination) temperature, a glass temperature, a PCB temperature, an Ambient Light Sensor (ALS) temperature, a power supply voltage, and the like. The display module information may include, for example, one or more of brightness, ambient light intensity (ALS), picture enhancement (IE) status, and the like. The Video information may include, for example, one or more of GMSL/Video link quality, watermark information, and the like. The touch information may include, for example, coordinate values and the like. The general information may include, for example, one or more of CPU load, security status, firmware version information, etc.
In one or more embodiments, the controller 120 can also indicate different diagnostic information by displaying different colors on the display screen module 111. For example, the controller 120 may enable display of different colors on the display screen module 111 through the image enhancement module 113 to indicate different diagnostic information. It is understood that the controller 120 may also directly cause the display module 111 to display different colors to indicate different diagnostic information without going through the image enhancement module 113. For example, a GMSL link error may be indicated by displaying blue full screen, a video error by displaying yellow full screen, and a poor connection quality by displaying green full screen.
The in-vehicle display screen 100 further includes a computer-readable storage medium 140 having stored thereon a plurality of instructions to be executed by the controller 120 to implement a diagnostic information display method of the in-vehicle display screen as will be described in detail below.
