摘要:
Disclosed is a full color flat display panel by using an organic electro-luminescent(EL) device, a manufacturing method thereof and a driving circuit of the organic EL device, in particular, which includes first, second and third pixels, a plurality of first electrodes, and a plurality of second electrodes perpendicularly intersecting the first electrodes, in which each of the first, second and third light emitting pixels is arranged in each of intersecting positions of the first and second electrodes. Light emitting pixels are arranged to have different areas according to luminous efficiency so that a red light emitting area with relatively poorer efficiency is sized larger than a blue or green light emitting area thereby manufacturing an efficient full color organic EL display panel. Also, the influence from the line resistance in the anode lines and the cathode lines is reduced when a constant current is introduced into the device structured of the RGB array in order to realize the white light as full color. Thus, the voltage loss on the line resistance is prevented and the area ratio of the device is adjusted to make each of the RGB pixels for generating the white light have the similar value of drive voltage thereby minimizing power loss.

A three-dimensional (3D) space interface apparatus and method are provided. The 3D space interface apparatus provides an interface in which a user may directly touch and transform a 3D virtual object of a 3D space, which is shown in various ways depending on a position of the user. The 3D space interface apparatus may provide for manipulation of the 3D virtual object by the user using a sensing signal that senses the position and movement of a manipulation object the user. Specifically, an interface unit of the apparatus verifies, using the sensing signal, whether a predetermined movement of the manipulation object has occurred or whether a contact between the 3D virtual object and the manipulation object has been made, and generates a predetermined reaction corresponding to the predetermined movement or the contact.
