A touch sensing device and an image display device using the same are discussed. The touch sensing can include touch sensors included in an image display panel, a touch sensing circuit unit configured to supply a driving signal to the touch sensors, receive a touch voltage from the touch sensors and generate sensing data based on a touch sensing result of the image display panel, and a micro control unit configured to determine whether or not the plurality of touch sensors, the touch sensing circuit unit and a self-stored firmware operate normally when a power source of the touch sensing device is turned on, and allow a touch sensing operation to be operated normally or delay a reset operation in a predetermined period unit and repeatedly perform the reset operation in a predetermined delay period unit based on a result of previous determination.

The present invention relates to an ink composition containing a multifunctional adhesive suitable for a three-dimensional (3D) printer and the use thereof. The multifunctional adhesive of the present invention contains a compound with a catechol group and exhibits excellent adhesion to various materials (e.g. dry plaster powders, polymers, metals, ceramics, and composite materials). The use of the ink composition of the present invention containing the multifunctional adhesive enables the processing of various functional materials that were difficult to fabricate into a 3D structure. Therefore, it is highly likely that the ink composition of the present invention can effectively create a market for functional materials for a 3D printer and find new areas of application (e.g. automotive, medical, fashion, aviation/aerospace, construction, consumer electronics, entertainment, etc.).

A display device is disclosed, which may supply gate signals to allow pulse widths of gate signals supplied to adjacent gate lines to be overlapped with each other and at the same time minimize cost increase caused by increase of the number of line memories. The display device comprises a display panel, a gate driver and a timing controller. The display panel includes gate lines, data lines and pixels provided at crossing areas between the gate lines and the data lines. The gate driver supplies gate signals to the gate lines. The timing controller supplies a start signal and gate clock signals for controlling an operation timing of the gate driver to the gate driver. One frame period includes an active period for supplying the gate signals to the gate lines and a vertical blank period for not supplying the gate signals to the gate lines, and the start signal is supplied within the vertical blank period.

The exemplary embodiment suggests an apparatus and a method for driving a light source of a backlight unit. The apparatus for driving the light source of the backlight unit comprises a plurality of LED columns; a power output terminal and feedback terminals connected to the LED columns; and an LED driver sequentially driving the LEDs according to sequentially delayed PWM signals. The LED driver decides an operable number of LED channel based on the signals input through the feedback terminals, and sequentially delays the PWM signals with the phase difference controlled by the number of LED channel.
