Abstract: A method for adjusting frame brightness is provided. First, an image data in YUV format is received. Next, a dimming curve is determined according to an overall average pixel level value of the image data and a number distribution of pixel level values. Then, the image data is divided into a plurality of blocks, and a block average pixel level value of pixels in each of the blocks is calculated. Thereafter, the block average pixel level values are substituted into the dimming curve to obtain a plurality of block brightness values. Afterward, the image data is outputted and backlight sources corresponding to each of the blocks are driven to provide the block brightness values to each of the blocks for displaying a frame.

Abstract: A base structure is used for bearing a display. The base structure includes a support and a seat.

Abstract: An audio system including an inverter, a first amplifier, a first mixer, a main speaker, and a first audio output port is provided. The inverter receives a first audio signal and inverts the first audio signal into an inverted audio signal. The first amplifier receives the inverted audio signal from the inverter and multiplies the inverted audio signal by a first gain to generate a first compensating audio signal. The first mixer receives a second audio signal and mixes the first compensating audio signal with the second audio signal to generate a first low-interference audio signal. The main speaker receives and plays the first audio signal. The first audio output port receives the first low-interference audio signal from the first mixer and transmits the first low-interference audio signal to a first external speaker. An electronic device and a car audio system capable of generating the low-interference audio signal are provided.

Abstract: A method for increasing a frame contrast ratio is suitable for a liquid crystal display (LCD) having a direct-type light emitting diode (LED) backlight module. The method includes establishing a local dimming demo mode in an on-screen-display (OSD) menu of the LCD, so as to determine to turn on or turn off a local dimming control function. Besides, according to this method, when the local dimming demo mode is turned on, the local dimming control function is continuously and repeatedly turned on or turned off in the direct-type LED backlight module in a time-division manner based on image contents in the whole frame of the LCD, so as to increase the frame contrast ratio of the LCD.
