| 20140261169 | SPUTTERING APPARATUS FOR REDUCING SUBSTRATE DAMAGE AND METHOD FOR APPLYING THE SAME - The present disclosure discloses a sputtering apparatus for reducing the damage to the base board caused by ITO sputtering and the method thereof. The sputtering chamber of the sputtering apparatus includes a base board connection structure for setting a base board and a target connection structure for setting a target. The target connection structure makes the target locate on the side of the base board connection structure. The target connection structure forms a precalculated angle with the base board. There is a space between the target and the base board. The target connection structure includes a negative potential generator for generating negative potential. The negative potential is applied to the target which is connected to the target connection structure. The sputtering chamber of the apparatus further includes an anode plate which is in parallel with the target material. | 09-18-2014 |
| 20140256118 | METHOD FOR FORMING POLYSILICON USING HIGH ENERGY RADIATION SOURCE - A method for forming polysilicon using high energy sources of radiation includes the steps of providing a laser system which has at least two laser sources with different wavelengths, a dichroic mirror, a reflecting mirror and a substrate; generating a laser beam by the laser sources to irradiate towards the substrate perpendicularly by the dichroic mirror and the reflecting mirror which are faced to the laser source and meet the laser sources at a certain angle; placing the reflecting mirror above the dichroic mirror; placing the a semiconductor thin-film material on the substrate. The advantages of the above technical solution are that as follows: the crystallization rate of poly-silicon is effectively increased; the usage frequency of the excimer laser is reduced; the cost thereof is reduced; the throughput of annealing is affectively improved. | 09-11-2014 |
| 20140250687 | METHOD OF FABRICATING FLEXIBLE ELECTRONIC DEVICES - The present disclosure is related to a method of fabricating display panels, especially to a method of fabricating flexible electronic devices. By means of adding an inorganic membrane with surface roughness between a bonding layer and a PI film, in order to effectively improve the dimensional stability of plastic substrate and the water/oxygen barrier property of flexible substrate during the PI film fabrication and the follow-up process, improving the yield of good products and prolonging the working life thereof. | 09-11-2014 |
| 20140238105 | DEVICE FOR DETECTING EVAPORATION SOURCE AND METHOD FOR APPLYING THE SAME - The present disclosure relates to a process for manufacturing Organic Light-Emitting Diode (OLED) display panel, and in particular to a device and a method for detecting evaporation source. Through installing a mobile detector above a linear evaporation source, the vapor-deposition rate of the whole linear can be timely and effectively detected. The feedback of uniformity of vapor-deposition can be effectively given, and at the same time the abnormity of the vapor-deposition can be found. Meanwhile, in order to increase the yield and quality of product as well as prevent the evaporation source pollution caused by the dropping of some defects such as organic material or dust, the mobile detector is locked in one side of the evaporation source when it does not work. | 08-28-2014 |
| 20140192038 | OLED PIXEL DRIVING CIRCUIT - The present invention relates to an OLED pixel driving circuit which has a data input unit for sending out controlling signals, a voltage storage unit for storing voltages from a first power source, a driving unit for receiving the controlling signals from the data input unit to selectively activate the voltage storage unit, a second power source providing a voltage to be stored in the voltage storage unit; and a switch connected to the second power source to offset potential loss of the first power source from the voltage stored in the voltage storage unit. The compensation circuit can not only compensate the non-uniformity of the threshold voltage but also eliminate the non-uniformity of the OLED display caused by the power IR drop, so that the effect of display of the OLED are maximally improved. | 07-10-2014 |
