The invention discloses a display screen blank screen detection method, display screen blank screen detection equipment and a vehicle, the display screen blank screen detection method is used for detecting the blank screen problem of a vehicle-mounted machine system, the vehicle-mounted machine system comprises a display screen module, a vehicle-mounted machine module and a software link, the software link is connected with the display screen module and the vehicle-mounted machine module, and the software link is connected with the display screen module and the vehicle-mounted machine module. Applying electrostatic energy to a display screen of the display screen module; in response to the process of applying the electrostatic energy to the display screen, detecting the input voltage of the display screen module if the display screen is black; in response to the fact that the input voltage of the display screen module is lowered, prompting to overhaul or adjust hardware of the vehicle-mounted terminal module and line connection of the vehicle-mounted terminal module; and in response to the fact that the input voltage of the display screen module is not lowered, prompting to overhaul or adjust hardware of the display screen module and circuit connection thereof. Therefore, a prompt for overhauling or adjusting hardware and circuit connection of the module can be sent in a targeted manner, the display screen is prevented from being restarted repeatedly, and the service life of the display screen is effectively prolonged.
本申请公开了一种显示屏黑屏的检测方法、显示屏黑屏的检测设备以及车辆,该显示屏黑屏的检测方法用于检测车机系统的黑屏问题,其中,车机系统包括显示屏模块、车机模块及软件链路,软件链路连接显示屏模块和车机模块,对显示屏模块的显示屏施加静电能量;响应于对显示屏施加静电能量的过程中,显示屏出现黑屏,则检测显示屏模块的输入电压;响应于显示屏模块的输入电压被拉低,提示检修或调整车机模块的硬件及其线路连接;响应于显示屏模块的输入电压没有被拉低,提示检修或调整显示屏模块的硬件及其线路连接。由此,可有针对性的发出提示检修或调整该模块的硬件及线路连接,避免反复重启显示屏,有效的提高显示屏的寿命。
