Abstract:
An apparatus and method are provided to rapidly and accurately measure the variation of capacitance in a panel load of a touch sensor and thus increase touch sensitivity and noise resistance. The apparatus includes a panel driver configured to drive a panel load in the touch sensor according to a reference voltage, and a capacitive load detector configured to measure capacitance of the panel load by sensing a panel load driving current that is applied to the panel load by the panel driver.
Abstract:
There is provided a method of manufacturing a light source module including: preparing a board including circuit wirings and a lens having an accommodation groove formed in a bottom surface thereof; attaching a buffer film to a bottom surface of the accommodation groove of the lens; mounting and arranging a plurality of light emitting devices on one surface of the board such that the plurality of light emitting devices are electrically connected to the circuit wirings; mounting the lens on the board such that the plurality of light emitting devices are accommodated within the accommodation groove in a state in which the buffer film faces the plurality of light emitting devices; and attaching the lens to the board such that the buffer film is tightly attached to upper surfaces of the plurality of light emitting devices and the bottom surface of the accommodation groove.
Abstract:
A light emitting device is provide comprising a light emitting diode (LED) chip having a first main surface and a second main surface opposing the first main surface, and one or more side surfaces extending between the first main surface and second main surface. A plurality of electrodes is disposed on the first main surface. A wavelength conversion film is disposed on the second main surface. A mark is formed in the wavelength conversion film. The mark contains orientation information of the light emitting device, thereby enabling the light emitting device to be properly oriented on a receiving substrate.
