An electronic device is capable of having a minimum sensing pressure with a low value through a resistive type force touch sensing method, wherein the electronic device may include a force sensing panel having a force sensor member whose shape is changed according to a touch pressure applied to a cover window so as to electrically connect first and second electrodes prepared on the same plane and provided in parallel.

Electronic device

An electronic device has a force touch function which is capable of minimizing a degradation of picture quality, wherein the electronic device may include a housing having a receiving space, an image display module disposed in the receiving space, and a force sensing panel disposed between a bottom surface of the housing and the image display module, which enables a user's force touch to be sensed through the force sensing panel, and to minimize a degradation of picture quality caused by heat.

Electronic device having force touch function comprising a display panel and a force sensing panel disposed entirely below the display panel

A touch sensing device includes a touch screen including Tx lines, Rx lines crossing the Tx lines, and touch sensors formed between the Tx lines and the Rx lines, and a touch screen driving circuit which senses all the touch sensors of the touch screen in a first sensing step to detect the presence or absence of a touch input, and then again senses the touch sensors, in which the touch input is detected as a first sensing result, in a second sensing step to detect a position of the touch input. When there is no touch sensor, in which the touch input is detected as the first sensing result, the touch screen driving circuit repeats the first sensing step.

Touch sensing device

A touch screen apparatus and a driving method thereof are provided. The touch screen drive circuit performs a setup operation for selecting Tx lines to be supplied with the drive signal and Rx lines to receive the voltages of the touch sensors, a sensing operation for supplying a drive signal to the Tx lines and receiving and sampling touch sensor voltages through the Rx lines, an ADC operation for converting the sampled voltages into digital data, a coordinate detection operation for analyzing the digital data by a preset touch detection algorithm and estimating the coordinates of a touch input position, and a data transmission operation for transmitting touch coordinate data comprising the coordinates to an external system. At least two operations among the setup operation, the sensing operation, and the ADC operation are performed in parallel.

Touch screen apparatus and driving method thereof

A liquid crystal display includes a liquid crystal display panel, a backlight unit providing light to the liquid crystal display panel, a bottom cover receiving the backlight unit, and at least one heat generation sheet disposed between the backlight unit and the bottom cover. The at least one heat generation sheet generates a radiant heat for increasing a surface temperature of the liquid crystal display panel.
