Abstract: 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.

Abstract: The disclosure discloses a TV backlight control method, which includes the following operations: acquiring current first ambient brightness information and a user type in a space where a TV set is located; determining a backlight adjustment value according to the first ambient brightness information and the user type. The brightness value of the TV backlight is reduced according to the backlight adjustment value. The present disclosure further discloses a control device, a TV set and a readable storage medium.

Abstract: 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.
