According to the delay control system for the power source of the lithium battery fork lift truck, it is ensued that the instrument is lightened rapidly after the fork lift truck starts to operate, and all electrical components are powered off when the fork lift truck stops operating; and hot plug hazards are avoided, and the power-lack hazard caused by long-time storage of a lithium battery is effectively avoided.

The invention discloses a method and system for quickly drawing a circular trajectory. The method includes the following steps: Step 1. When the mobile terminal is in a standby state, detect in real time whether a touch circular trajectory is generated on the touch screen; It is determined that the mobile terminal has a lighted touch screen operation when the trajectory is shaped; step 2. collects the coordinates of the touch circular trajectory; step 3. obtains the clock direction sequence of the circular trajectory according to the coordinates of the circular trajectory, and the clock direction sequence includes Clockwise and counterclockwise; step 4. Calculate the four coordinate points of the tangent line along the edge of the circular trajectory, draw a circular trajectory that coincides with the generated touch circular trajectory according to the order of the clock direction, and light up the screen. In the standby mode of the present invention, the user operates a circular gesture to light up the screen, and only needs to obtain the four coordinate points and the order of the clock direction for drawing the edge tangent of the circular trajectory, to quickly draw a circular rule, quickly light up the screen, and improve user experience.

The invention discloses a method for controlling the starting of an electric ballast of a high strength gas discharger lamp. Lamp resistance can be acquired by the method based on the voltage and the current of the lamp. The characteristics of a bulb can be judged and real time control can be achieved according to the lamp resistance. As the state of the lamp can be judged most effectively and correctly by the lamp resistance, the accuracy and the reliability of control can be ensured. The bulb is lighted quickly by controlling the starting of the bulb. The control method can ensure that the starting of the bulb is smooth and the bulb does not flicker. In addition, the service life of the bulb is protected by shortening the time of overpower operation of the bulb as much as possible.

The embodiment of the present application discloses a method, device, terminal, and storage medium for controlling a screen, which belong to the field of computer technology and enable the terminal to detect whether the rotation angle generated by itself from the first moment to the second moment is greater than the rotation angle threshold. If the angle is greater than the rotation angle threshold, then it is detected whether the screen is in a down-tilt state. When the screen is in a down-tilt state, the screen is turned on. When the screen is turned on, it starts to detect whether the terminal meets the preset conditions within the target time period. When the terminal If the preset condition is met within the target time period after lighting up, the screen will be turned off. It can be seen that this embodiment can turn on the screen when the rotation angle of the terminal in the specified time period is greater than the threshold, and then turn off the screen when the terminal meets the preset conditions, so as to ensure that the terminal quickly lights up the screen and prevents the terminal from being delayed. The effect of continuous power consumption after the screen is turned on.

A display device includes a display panel, a backlight module and a backlight control circuit. The backlight module is electrically connected to the display panel for providing backlight to the display panel. The backlight module further includes a plurality of backlight driving circuits. The backlight control circuit is electrically connected to the backlight module, and the backlight control circuit is used to control the backlight module to operate in one of the first display mode and the second display mode.

The application discloses an intelligent high-intensity discharge (HID) lamp lighting method. The method comprises the following steps: detecting a power voltage (Vin), a load voltage (Vlamp) and a load current (Ilamp); determining the type and the state of the load according to the detection result; and according to the type and the state of the load, outputting a corresponding control signal to control the load. In addition, the application also discloses an HID electronic ballast and an HID illumination system, according to the scheme, an HID lamp that is turned off due to grid voltage fluctuation is determined as the thermolamp; after the cooling of the HID lamp, the HID lamp is turned on again, thereby preventing the hot HID lamp from being damaged due to repeated lighting triggering and thus prolonging the service life of the HID lamp. When the load is switched to another HID lamp, the open-circuit protection is identified and the HID lamp is lighted after the first fixed time interval, thereby realizing rapid HID lighting.
