A method for displaying a 360-degree image in an electronic device, and an electronic device thereof are disclosed. The apparatus includes a display, and a at least one processor connected operatively to the display. The at least one processor is configured to acquire 360-degree image data and metadata corresponding to the 360-degree image data, and display an object including a first indicator and a second indicator on the display by using the metadata. The first indicator indicates an angle of view or capturing x-direction along a horizontal direction in a three-dimensional (3D) model space for a first area of the 360-degree image data, and the second indicator indicates an angle of view or capturing y-direction along a vertical direction in the 3D model space.

Disclosed herein is an Active Matrix Organic Light-Emitting-Diode (AMOLED) drive circuit using transient current feedback. The AMOLED drive circuit includes a current Digital-to-Analog Converter (DAC), a data line drive transistor, a constant current source, a variable current source, a differential amplifier, and a transient charging current control unit. The DAC generates current corresponding to input digital data. The data line drive transistor is configured such that the drain terminal thereof is connected to the output node of the current DAC. The constant current source is connected between the source terminal of the data line drive transistor and a ground. The variable current source is connected between both the output node of the current DAC and the drain terminal of the drive transistor, and a voltage source. The differential amplifier is configured to input the output voltage thereof to the gate terminal of the drive transistor. The transient charging current control unit is configured to increase or decrease the bias current of the variable current source depending on variation in the voltage of the output node of the current DAC.
