Abstract:
PURPOSE: An RFID display pixel and a display panel using thereof are provided to reduce the power consumption by supplying an electric power to drive from an RFID tag. CONSTITUTION: An RFID(radio frequency identification) display pixel(100) comprises the following: an RFID tag(140) including an IC chip and an antenna; a display device(120) receiving information from the antenna to drive the display device while the predetermined information is saved in the RFID tag; and an RFID reader(200) transmitting or renewing the saved information by a wireless communication. The display device receives a necessary power source to drive the display device by the RFID tag.

A method for aging a field emission device is provided to decrease an error rate of a display device by repairing a short-circuit portion of the tri-pole field emission device. A tri-pole field emission device includes a cathode electrode(110), an anode electrode(140), a gate electrode(120), an insulation layer(125), and an emitter(130). The gate electrode is laminated on the cathode electrode. The insulation layer is formed between the cathode and gate electrodes. The emitter is formed in an emitter hole, which is formed on the gate electrode. The emitter is formed on the cathode electrode to be connected to the cathode electrode. The emitter is made of one of CNT(Carbon Nano Tube), silicon, and molybdenum.

Abstract:
A method of manufacturing a field emission array type light emitting unit is provided to improve optical efficiency as improving uniformity of emitted light. A field emission array type light emitting unit includes a rear substrate(20), a front substrate(10), and plural spacers(33). The rear substrate includes a cathode electrode and a CNT(Carbon Nano Tube) emitter. The front substrate includes an anode electrode and a fluorescent layer(12). The spacers are arranged to maintain a constant distance between the front and rear substrates. Diffusion patterns(11) are formed on a front surface of a glass substrate for the front substrate through a wet etching process. The front surface of the glass substrate is divided into at least two regions. The diffusion patterns having different diffusion ratios are formed on the respective regions on the glass substrate.
Abstract:
A field emission display device and a field emission type backlight device having a sealing structure for vacuum exhaustion are provided to remove a rear space by removing an exhaust tube protruded to a backside of a panel. A field emission display device includes a cathode substrate and an anode substrate in order to form predetermined images. A vacuum-exhausted panel space is formed between the cathode substrate and the anode substrate. A sealing member(150) is formed along edges between the cathode substrate and the anode substrate in order to seal the panel space. At least, one inlet(152) exposed to the panel space and an exhaust path for connecting the display device to the outside are formed in the sealing member. The sealing member includes a rectangular frame and a pair of exhaust tubes and a pair of frit bars extended in a long side and an exhaust path formed along a length extended in a short side.
