Abstract: A display device includes a substrate having a first surface on which a light emitting element is located, a second surface on which a driving unit for driving the light emitting element is located, the second surface being opposite the first surface, and a first side surface between the first surface and the second surface, a first pad on the first surface of the substrate and electrically connected to the light emitting element, a second pad on the second surface of the substrate and electrically connected to the driving unit, and a side wiring on the first surface, the second surface, and the first side surface of the substrate to electrically connect the first pad and the second pad. The side wiring includes a first side wiring and a second side wiring spaced from each other.

Abstract: The embodiment relates to a data driving device for driving pixels of a display panel. In the data driving device, two adjacent DACs can have different gate loads for the same gray level value so that the fluctuation of the gate load according to the gray level value is reduced.

Abstract: Disclosed herein is a touch sensor module, including: a flexible cable provided with a terminal part; an adhesive layer formed to transfer an electrical signal by being contacted on one surface of the terminal part; a base substrate including an electrode pad which is formed to correspond to the terminal part and formed to be contact on the other surface of the adhesive layer; and a first passivation layer coating one end of the electrode pad.

Abstract: A bearing holder and a spindle motor having the same are disclosed. The bearing holder in accordance with an embodiment of the present invention can include a body, which has an insertion hole formed therein such that a bearing is inserted into the insertion hole, a first supporting protrusion, which is protruded downward from a bottom surface of the body along a circumference of the insertion hole, and a first bent indentation, which is formed on an inner circumferential surface of the first supporting protrusion such that the first supporting protrusion is bent toward an inner side. Thus, unnecessary deformation in the bearing holder can be prevented while the bearing holder is coupled to a base plate. Moreover, since the bearing holder forms an accurate positional relationship with respect to the base plate, noise and vibration can be prevented from occurring during the operation of the motor.

Abstract: Disclosed herein is a brushless DC motor. The brushless DC motor includes a rotating shaft, a bearing, an integrated washer holder, a rotor casing, a stator and a support plate. The bearing rotatably supports the rotating shaft in the radial direction. The integrated washer holder supports the lower end of the rotating shaft and the circumferential outer surface of the bearing. The rotor casing integrally rotates along with the rotating shaft. A rotor magnet is attached to the inner surface of the rotor casing. The stator is provided around the circumferential outer surface of the integrated washer holder such that the stator faces the rotor magnet. Thus, when external electric power is applied to the stator, the rotor casing is rotated by reciprocal action between the stator and the rotor magnet. The integrated washer holder is mounted to the support plate.
