Patent ID: 7170534

Claim:
A display device capable of automatically controlling an image display direction comprising: an image display unit for displaying an image; a slope information processing unit for detecting a slope information of the image display unit; a control unit for receiving the slope information of the image display unit detected by the slope information processing unit, and producing an image control signal according to a tilted state of the image display unit; an image display control unit for receiving the image control signal produced by the control unit, and processing the image signal to be displayed on the image display unit; and an image display memory for storing the image signal processed in the image display control unit according to the image control signal, and supplying the stored image signal to the image display unit; wherein the slope information processing unit essentially comprises a location detection unit for detecting the slope information of the image display unit and a quantization processing unit for quantizing the slope information of the image display unit by the location signal detected by the location detection unit to be matched with a set period; wherein the location detection unit comprises at least one gyro-sensor; and wherein the quantization processing unit allots installation values with a predetermined gap according to the tilted state of the image display unit.
