    Abstract: To improve the use efficiency of a vapor-deposition material, reduce the manufacturing cost of a light-emitting device including a layer containing an organic compound, and shorten the manufacturing time for manufacturing a light-emitting device. Inside of a film formation chamber is made in a reduced pressure state, and conductive-surface substrate is energized, so that the conductive-surface substrate is heated rapidly, and a material layer over the conductive-surface substrate is evaporated in a short period of time to be vapor-deposited on a film formation substrate, whereby film formation of the material layer is performed on the film formation substrate. Note that the heating area of the conductive-surface substrate which is rapidly heated is set to be the same size as the film formation substrate so that film formation on one film formation substrate is completed by one heating.

  • Patent number: 8043874
    Abstract: Methods and systems for coating of semiconductor devices using droplets of wavelength conversion or phosphor particles in a liquid medium. A plurality of nozzles delivers a controlled amount of the matrix material to the surface of the semiconductor device, with each of said nozzles having an opening for the matrix material to pass. The opening has a diameter wherein the diameter of the phosphor particles is less than or approximately equal to one half the diameter of the opening. The phosphor particles are also substantially spherical or rounded. The nozzles are typically arranged on a print head that utilizes jet printing techniques to cover the semiconductor device with a layer of the matrix material. The methods and systems are particularly applicable to covering LEDs with a layer of phosphor materials.

  • Patent number: 8040058
    Abstract: The preparation of microlenses on a substrate and light emitting devices employing microlenses on the surface from which light is emitted is described. The miscrolenses are formed on a surface that has been coated to have functionality that promotes a sufficiently large contact angle of the microlense on the surface and contains functionality for bonding the microlense to the coating. The microlenses are formed on the coating by deposition of a microlense precursor resin as a microdrop by inkjet printing and copolymerizing the resin with the bonding functionality in the coating. The coating can be formed from a mixture of silane coupling agents that contain functionality in some of the coupling agents that is copolymeriable with the resin such that the microlens can be formed and bonded to the surface by photopolymerization.

  • Patent number: 7998526
    Abstract: A system and method for depositing a phosphor composition onto a light emitting device improves manufacturing yield, simplifies conventional processes, and decreases costs. For example, a method of dispensing a phosphor composition onto a light emitting device includes dispensing a portion of the phosphor composition onto the light emitting device utilizing a plurality of colored phosphor dispensers each for dispensing a respective type of phosphor. Power is applied to the light emitting device to emit light, and a characteristic the light emitted by the light emitting device is detected. Phosphor mixing and phosphor dispensing are dynamically controlled. Therefore the color characteristics of phosphor dispensed on LEDs are consistent. The system and method may also reduce the difference between detected characteristic of the light and a desired characteristic of the light.

  • Publication number: 20110176097
    Abstract: In a liquid crystal display device small in the size and having a narrow frame, an alignment film can be coated by ink jet printing, by coating a rapidly drying peripheral alignment film 109 in the shape of a frame to a TFT substrate 100 having a display region having pixel electrode 107 and a peripheral region thereof by ink jet printing, and then coating a display region alignment film 108 drying slower but excellent in the leveling effect by ink jet printing. While the display region alignment film 108 dries slowly, since the peripheral alignment film 109 formed to the periphery functions as a stopper, the shape of the alignment film can be defined accurately, thereby enabling to prevent lowering of the adhesion of the seal member 20 under the effect of the alignment film. This can be applied also on the side of the counter substrate 200.
