One embodiment of a touch panel comprises a substrate; a sensing electrode formed over the substrate, the sensing electrode configured to sense finger touch input and to provide haptic feedback; and an antenna formed over the substrate, the antenna configured to sense pen touch input; wherein a first mode in which the finger touch input is sensed, a second mode in which the haptic feedback is provided, and a third mode in which pen touch input is received are time-divisionally performed.

Touch panel

Embodiments relate to a touch panel operable in a first haptic mode and a second haptic mode. The touch panel includes first electrodes and second electrodes intersecting the first electrodes. The touch panel further includes an elastic dielectric member disposed between the first electrodes and the second electrodes to separate the first electrodes and the second electrodes. The first electrodes are applied with a first voltage during the first haptic mode. The second electrodes are applied with a reference voltage in the first haptic mode. A subset of the second electrodes is applied with a second voltage to generate electrostatic force between the subset of the second electrodes and a user's finger in the second haptic mode. The elastic dielectric member vibrates in response to the first voltage applied to the first electrodes in the first haptic mode.

Apparatus for driving of touch panel

A curved liquid crystal display device includes a liquid crystal display panel, a backlight unit, a bottom cover and a reinforcement frame. The liquid crystal display panel includes a thin film transistor substrate and a color filter substrate. The backlight unit applies light to the liquid crystal display panel. The bottom cover supports the backlight unit and has a flat shape. The reinforcement frame has a predetermined curvature and is attached to the bottom cover. The flat bottom cover is mounted on the reinforcement frame such that the flat bottom cover has the predetermined curvature of the reinforcement frame.

Curved liquid crystal display device

A flexible printed circuit board (FPCB) capable of improving strength is disclosed, the FPCB comprising a base film; a copper layer on the base film, the copper layer including a circuit pattern, and a strength-reinforcing pattern in an area without the circuit pattern; and a coverlay film on the copper layer.
