Abstract: Disclosed is an organic light-emitting display device having a micro lens array (MLA) structure applied to a display panel in order to improve light extraction efficiency. In the organic light-emitting display device, an optical device, including a reactive mesogen (RM) and a dye, is provided between a polarizer and a quarter wave plate (QWP) to block light spreading to a viewing angle, thereby reducing a diffuse reflection component due to the application of the MLA structure.

Abstract: A method of controlling a supply of electric power to an electric load and a circuit thereof are disclosed. The circuit includes a control voltage generating part means for generating a control voltage which decreases over time, an amassing part for amassing the control voltage upon a voltage signal increasing over time and discharging the amassed voltage nearby a zero crossing point of AC voltage from the AC source in order to generate a saw-tooth wave, a trigger signal generating part for generating trigger signals based on the saw-tooth wave, wherein the phase angle of the trigger signals varies depending on the saw-tooth wave, and a switch part for supplying electric energy from the AC power source to the electric load in response to the trigger signals. Therefore, electric power being supplied to an electric load fades out.
