Abstract: Provided are a random wrinkle structure-formable compound, a composition including the same, a film including a random wrinkle structure, a method of forming the film, and an organic light emitting device including the film. A compound according to the present invention is coated and then, a film having a surface structure of random wrinkles may be simply formed through simple ultraviolet (UV) curing or thermosetting. When the film thus formed is used in an organic light emitting device, light generated from the organic light emitting device is scattered on surfaces of the random wrinkles to prevent light guide or total reflection, and thus, light is extracted to the outside. That is, a random structure disposed at the outside of the device performs a light extraction function and consequently, light efficiency of the organic light emitting device may be increased.

Abstract: A pixel circuit includes a sensing block, a stimulation block, a first line control circuit, and a second line control circuit. The sensing block outputs biometric data of a biosignal in response to a first selection signal. The stimulation block radiates a stimulation signal in response to a second selection signal. The first line control circuit outputs the first selection signal for selecting the sensing block as a target sensing block, and outputs the second selection signal for selecting the stimulation block as a target stimulation block. The second line control circuit processes characteristic data associated with the biometric data and the stimulation signal.
