摘要： An image quality optimization method based on local dimming includes: based on an input image signal, calculating a PWM duty cycle of a current image signal corresponding to each of backlight regions; comparing a preset first PWM duty cycle and a preset second PWM duty cycle with each PWM duty cycle of the current image signal corresponding to each of the backlight regions to determine whether there exists a high backlight region and a low backlight region in the backlight regions; in determining that there exists the high backlight region and the low backlight region, decreasing a PWM duty cycle of the low backlight region to decrease an output current, and increasing a PWM duty cycle of the high backlight region to increase an output current, thereby increasing a contrast of the current image signal. The present application also provides related apparatus and computer readable storage medium.

摘要： A smart control device is provided. The smart control device and a display panel of a smart TV are separately provided. The smart control device includes: a lifting unit, and a charging unit, and a main control unit including a main control circuit board configured to control the display panel. The lifting unit includes a bearing platform configured to bear a target object, an infrared sensor, and a lifting motor. The main control unit is configured to control an operation of the lifting motor and adjust a position of the bearing platform according to a detection signal of the infrared sensor. The charging unit is configured to charge the target object upon receiving a preset position signal generated in response to a determination that the bearing platform reaches a preset position.
