Automatic controllable display device according to image display direction

(amended) An operation method of a display device capable of automatically controlling an image display direction, the method comprising the steps of:

• a) acquiring a slope information of an image display unit;
• b) extracting an image display control data fit for the tilted state acquired by the image display unit;
• c) storing an image data in a memory according to be matched with the extracted image display control data;
• and
• d) outputting the image data stored in the memory on the image display unit;
• wherein the step (a) comprises the steps of;
• (a-1) detecting location information of the image display unit by a location detection sensor;
• (a-2) converting the detected location information of the image display unit to a digital signal;
• and (a-3) quantizing the slope information of the image display unit to be matched with a set period by referring to the location information of the image display unit converted to the digital signal;
• wherein the image display control data extracted in the (b) step comprises the information for a start point and an end point at which the image display is started and ended according to the tilted state of the image display unit, and a scan direction.

(amended) A display device capable of automatically controlling the image display direction, comprising:

• an image display unit for displaying an image;
• at least one gyro-sensor for detecting a slope information of the image display unit;
• an analog digital conversion unit for converting an analog signal of the slope information outputted from the gyro-sensor to a digital signal;
• a quantization processing unit for quantizing the digital signal outputted from the digital conversion unit, and outputting the quantized digital signal as a control data;
• a control unit for receiving the slope information of the image display unit detected by the quantization processing unit, and producing an image control signal according to the 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, and supplying the stored image signal to the image display unit;
• wherein the control unit comprises;
• a microcomputer for processing an essential operation;
• an input/output control unit for processing a communication between the microcomputer and the image display control unit;
• and a control unit memory for storing an image display control data which is essentially required in the control unit according to a slope of the image display unit.

(amended) A display device capable of automatically controlling an image display direction, comprising:

• an image display unit having a gyro-sensor auxiliarily installed and an image display panel on an upper side thereof to display image;
• a circuit installation unit placed on a lower side of the image display unit and hinge-coupled with one side of the image display unit, and provided with an element to control the image display direction by a slope of the image display unit detected by the gyro-sensor;
• a fixing unit installed on a lower side of the circuit installation unit to make the display device possibly fixed on a wall or a ceiling;
• and
• a portrait hinge vertically inserted into the circuit installation unit and the fixing unit to make the circuit installation unit possibly rotate.
