An image forming apparatus, guide providing method thereof, cloud server and error analyzing method thereof are provided. The image forming apparatus may include a scanner configured to scan a script and generate a scan image, a communicator configured to communicate with a cloud server, a display configured display a screen, and a processor configured to control the communicator to transmit the generated scan image to a cloud server, and in response to receiving an error solution guide of the scan image from the cloud server, control the display to display the received error solution guide.

Image forming apparatus, guide providing method thereof, cloud server, and error analyzing method thereof

A power system for an organic light emitting diode (OLED) display includes a power supplier and a power source controller. The power supplier respectively supplies a first power source voltage and a second power source voltage to first and second power source voltage application lines. The power source controller calculates a reference power source voltage corresponding to a maximum average grayscale using a distribution for each grayscale of first to third image data, models each voltage drop of the first and second power source voltages for first to third subpixels, and reflects the voltage drop to the reference power source voltage to change the second power source voltage.

Organic light emitting display device using an adjustable power source voltage and driving method thereof

A pixel capable of minimizing power consumption is disclosed. In one embodiment, the pixel includes an organic light emitting diode (OLED), a first transistor for controlling an amount of current supplied from a first power supply to the OLED to correspond to a voltage applied to a first node, and a second transistor and a third transistor coupled between a second node electrically coupled to a data line and the first node in parallel in a period where a scan signal is supplied.

Pixel for minimizing power consumption and organic light emitting display using the same

There is provided an organic light emitting display device capable of reducing power consumption by adjusting a voltage according to an input image and deterioration of the organic light emitting display device and a method of driving the same.
