A display device capable of controlling an external light and a control method are provided. Image display of the display device and the external light are synchronously controlled through a synchronization signal generated by a control module in the display device. The control module generates a first and a second light source control signal during first cycles and second cycles of the synchronization signal. The first and the second light source control signal are used to control the external light to operate at a first operation state and at a second operation state respectively. Through the techniques of controlling the external light by the display device, i.e. turning off or reducing illumination intensity of the external light every other specific period, both influence of the external light on contrast ratio and light reflection from the display device are reduced. Power of the external light is also saved.

A video system suitable for being set in one of several scene modes and controlling one of several ambient light sources is disclosed. The video system includes a storage unit, a signal transceiver, and a control module. The storage unit stores several brightness setting values, in which the brightness setting values correspond to the scene modes and/or several specification data respectively, and the specification data is contained in the several ambient light sources respectively. The signal transceiver is used for receiving the specification data of one of the ambient light sources. The control module is electrically coupled to the signal transceiver, and controls the signal transceiver to transmit a corresponding brightness setting value in the storage unit to the ambient light source according to the set scene mode and the received specification data.

Video system capable of controlling ambient light and control method thereof

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.

When an image frame is generated, a plurality of backlight blocks are driven according to percentage of the image frame being generated, and a left shutter and a right shutter of a pair of shutter glasses are switched according to the time the image frame is generated. In this way, ghost shadows resulting from right eye images or left eye images can be avoided.

A backlight module including a circuit board, at least one first light emitting diode (LED) device, at least one second LED device, and a reflection device is provided. The first and second LED devices are disposed on a carrying surface of the circuit board and electrically connected to the circuit board. The brightness of the first LED device is greater than that of the second LED device. The reflection device is disposed on the circuit board and exposes the first and second LED devices. The reflection device has at least one first reflection region disposed around the first LED device and at least one second reflection region disposed around the second LED device. The reflection ratio of the first reflection region opposite to the light-emitting energy of the first LED device is smaller than that of the second reflection region opposite to the light-emitting energy of the second LED device.

An image signal processing method is disclosed for maintaining high image display quality by avoiding signal-mode misjudgment. The image signal processing method includes generating a first threshold based on a plurality of motion values generated prior to a first time when an image input signal is detected to be of a film mode, generating a second threshold based on the first threshold and a first offset, generating a third threshold based on the first threshold and a second offset, and determining whether the image input signal between the first time and a second time is the film mode or a video mode based on the second and third thresholds.

In a signal coordinating method and apparatus, a pulse generating circuit receives a VSYNC signal and generates a plurality of critical pulses that define critical time periods from fields can control edges of the VSYNC signal. A determining circuit receives an HSYNC signal and the critical pulses, and generates a trigger signal upon detecting that a line scan control edge of the HSYNC signal appears during one of the critical time periods. A time delay loop introduces a time delay into the VSYNC signal upon receipt of the trigger signal to cause the critical time period to appear after the line scan control edge of the HSYNC signal.
