Touch sensing display device for sensing different touches using one driving signal

The present disclosure relates to a position detecting system. The position detecting system includes a display panel including a plurality of pixels. The position detecting system also includes a data driving unit configured to apply a first data voltage and a second data voltage to the display panel, wherein the first data voltage is associated with display of an image on the display panel during a first frame and the second data voltage is associated with display of patterns on the display panel during a second frame. The position detecting system further includes a position detecting sensor configured to capture an image of the patterns when a position detecting mode of the position detecting sensor is turned on.

Position detecting system and driving method thereof

The present invention relates to a display device including a touch sensor and a driving method thereof. A display device according to an exemplary embodiment of the present invention includes a plurality of data lines which extends in a first direction, a plurality of sensing output lines which extends in a second direction which is not parallel to the first direction and transmits a sensing output signal, a pixel electrode which is connected with the data line through a switching element, a touch sensor which is connected to the data line and the sensing output line and detects a touch, and a data driver which applies a displaying data voltage to the plurality of data lines during the image display period for one frame and applies a sensing input signal during a touch sensing period for one frame. The touch sensing period is included in a vertical blank period of the frame.

Display device including touch sensor and driving method thereof

A touch panel is provided that includes: a substrate; a plurality of X-axis lines disposed on the substrate; a plurality of Y-axis lines crossing the plurality of X-axis lines; and an insulating layer interposed between the X-axis lines and the Y-axis lines, in which at least one first X-axis line and at least one second X-axis line selected from among the plurality of X-axis lines are connected by a first connection portion, and among the plurality of Y-axis lines, a Y-axis line crossing the first X-axis line and the second X-axis line has a first area in a region where the Y-axis line overlaps the first X-axis line and a second area in a region where the Y-axis line overlaps the second X-axis line, and the first area and the second area are different from each other.

Touch panel

Disclosed are an optical film having a graded refractive index and a method of manufacturing the same. The optical film includes one or more antireflection films composed of a mesoporous material having a plurality of pores of a uniform size, and the pores of the mesoporous material are filled with air or a filler having a refractive index different from that of the mesoporous material, and thus the volume ratio of mesoporous material to filler in the pores thereof is controlled, thereby obtaining a desired magnitude of effective refractive index and ensuring a refractive index distribution in which the refractive indexes sequentially change, resulting in high antireflection performance. The method of manufacturing the optical film may be conducted using a nanowire growing technique, thus making it easy to realize mass production.
