Abstract: A driving apparatus for an organic light-emitting diode includes an organic light-emitting diode, a driving switch that drives the organic light-emitting diode in response to a control voltage applied to a gate terminal of the driving switch, a high-level voltage source that supplies a high-level voltage to the driving switch, a data driving circuit that supplies a data voltage to a data line of the driving apparatus, a reference voltage source that supplies a reference voltage to the driving apparatus, and a capacitor that applies the control voltage to the gate terminal of the driving switch, the control voltage being a difference between the data voltage and the reference voltage.

Abstract: A driving circuit of an organic light emitting display includes: a first PMOS transistor turned on in response to a driving signal to transfer a data signal; an OLED (organic light emitting diode) where an amount of light emitted is controlled by a control current; a second PMOS transistor for supplying the control current to the OLED; a third PMOS transistor connected to a node to which the first and second PMOS transistors are connected; a first capacitor connected between the first PMOS transistor and the third PMOS transistor; and a second capacitor connected between the second PMOS transistor and the first PMOS transistor.

Abstract: An organic light emitting diode device includes a substrate having first and second surfaces and a diode on the first surface of the substrate. The diode includes a first electrode, a second electrode facing the first electrode and an organic emitting layer between the first and second electrodes. Light is emitted from the diode toward the first and second surfaces of the substrate. A brightness compensation plate having a thickness that varies across a length of the plate is disposed on the second surface of the substrate for transmitting the light. The brightness compensation plate may improve a uniformity of a brightness of the organic light emitting diode device.

Abstract: The present invention relates to dermal replacement prepared from mesenchymal cells of hair follicle. As compared with fibroblast, the mesenchymal cells separated from the hair follicle, especially from the hair follicle in human beard produce a lot of growth factor and matrix protein stimulating cell-regeneration, and produce a little enzyme decomposing matrix protein. Therefore, the dermal replacement prepared from the present invention has more excellent cell-regeneration effect than the conventional artificial skin.

Abstract: The present invention discloses a hair trasplanter. A needle to be inserted into a scalp has a pointed end portion to reduce damage of the scalp, and a guide plate in adhered to an end portion of a sliding unit reciprocating in the longitudinal direction of the needle outside the needle, in order to prevent hair roots from being separated at the time of the separation of the needle. As a result, the hair roots inserted into a needle insertion groove are not damaged and are naturally settled in the scalp without modification, thereby stably performing the hair transplantation.
