Abstract: An organic light emitting device including a first electrode connected to a thin film transistor formed on a substrate, a second electrode opposite to the first electrode, and an organic laminate formed between the first electrode and the second electrode and including a hole transport layer, a multilayer-light emitting structure, and an electron transport layer. The multilayer-light emitting structure includes at least two light emitting layers emitting light of different colors through recombination of electrons and holes injected through the first and second electrodes, and a charge transport control layer formed of a bipolar material transporting both electrons and holes at boundaries between the at least two light emitting layers and controlling the amount of charges transported between the at least two light emitting layers.

Abstract: Exemplary embodiments of the present invention relate to a touch technology, and more specifically, to a signal control circuit, a power control circuit, a drive circuit, a timing controller, a touch system, and a touch sensitive display device and a driving method thereof that can simply swing various voltages in a display device for a touch mode period by using a modulated ground voltage obtained by swinging a ground voltage, thereby effectively providing touch driving and preventing unnecessary parasitic capacitance from being generated not only in an active area but also in all other areas.

Abstract: Discussed are a high efficiency reflector which reflects multiple color light, and a display device which can increase display quality by applying the high efficiency reflector thereto. The reflector includes a first reflective layer pair reflecting red light, a second reflective layer pair reflecting green light, and a third reflective layer pair reflecting blue light. The first to third reflective layer pairs are formed as a plurality of inorganic layers.

Abstract: Disclosed herein are a liquid crystal display panel and a method for fabricating the same wherein color reproducibility and superior image quality are achieved. The liquid crystal display panel comprises a color filter array substrate including a black matrix and a plurality of color filters arranged on a substrate, wherein each of the color filter includes a first color filter, a second color filter and a third color filter, each of them yielding a different color; and at least one selected from a fourth color filter yielding a mixed color of the first and second color filters, a fifth color filter yielding a mixed color of the second and third color filters, and a sixth color filter yielding a mixed color of the first and third color filters.

Abstract: A liquid crystal display device includes: first and second substrates facing and spaced apart from each other; a liquid crystal layer between the first and second substrates; a first polarizing plate on an outer surface of the first substrate; a second polarizing plate on an outer surface of the second substrate, the second polarizing plate including an anti-static pressure sensitive adhesive (ASPSA) layer; and a conductive tape electrically connected to the ASPSA layer.
