Abstract

A display device with automatic display adjustment. One or multiple brightness sensors in a display device detect environmental brightness signals and generate a brightness signal value, transmitted to a display control circuit of the display device. The display control circuit records, compares, and evaluates the brightness signal value and adjusts the display settings of the display device accordingly.

Claims

1. A display device with automatic display adjustment, comprising:

at least one brightness sensor, detecting environmental brightness and generating a brightness signal value; and

a display control circuit, coupled to the brightness sensor, processing the brightness signal value from the brightness sensor and automatically adjusting a default display setting of a display device accordingly.

2. The display device as claimed in claim 1, wherein the display control circuit records, compares, and evaluates the brightness signal value and adjusts the display settings of the display device accordingly.

3. The display device as claimed in claim 1 further comprising a storage medium, storing the default display setting and the brightness signal value.

4. The display device as claimed in claim 1, wherein the display device is a TV, monitor, LCD TV, plasma TV, projector, or LED billboard.

5. The display device as claimed in claim 1, wherein the brightness sensor is a circuit comprising a semiconductor element, an optical element, an integrated optical element, or a photoresistor.

6. The display device as claimed in claim 1, wherein the brightness signal is an optical signal, an analog signal, or a digital signal.

7. A display device with automatic display adjustment, comprising:

at least one brightness sensor, detecting environmental brightness to obtain an initial brightness signal value and continuing detecting the environmental brightness to obtain a first brightness signal value; and

a display control circuit, coupled to the brightness sensor, comparing the initial brightness signal value with the first brightness signal value when environmental brightness changes, and automatically adjusting display settings of a display device accordingly.

8. The display device as claimed in claim 7 further comprising a storage medium, storing the display settings and the brightness signal values.

9. The display device as claimed in claim 7, wherein the display device is a TV, monitor, LCD TV, plasma TV, projector, or LED billboard.

10. The display device as claimed in claim 7, wherein the brightness sensor is a circuit comprising a semiconductor element, an optical element, an integrated optical element, or a photoresistor.

11. The display device as claimed in claim 7, wherein the brightness signal is an optical signal, an analog signal, or a digital signal.
