Abstract:
PURPOSE: A driving method of a touch screen display device, a recording medium recording the driving method and touch screen display device are provided to exactly draw a touch location of an object by removing noise from a sensing signal provided from an optical sensor according to noise determining reference which is updated in real time in real time. CONSTITUTION: A touch sensor generates an input signal by touching an object(S11). The input signal is transformed into an output signal including one or more disable section with an enable section(S12). A noise determining standard of a sensing signal provided from an optical sensor is updated during disable of the output signal(S13).
Abstract:
PURPOSE: A touch screen panel is provided to form a dummy pattern between sensing lines arranged at a non-display region in order to prevent the exposure of the sensing lines. CONSTITUTION: A glass substrate is classified into a display region(20) and a non-display region(30) which is formed at an edge portion of the display region. Metallic pads are formed in the non display region adjacent to the display region in order to enable the electric connection to the patterns formed at the edge portion of the display region. Sensing lines(16) are formed at the non-display region to be connected to each metal pad. A dummy pattern(18) is formed between the sensing lines, and is made of the material same as that of the sensing line.

Abstract:
PURPOSE: A method and an apparatus for detecting a touch point are provided to detect a touch point of a finger accurately by analyzing an image obtained by an optical sensor. CONSTITUTION: An edge detector(231) detects an edge image of a finger image from an input image, and a touch point image generator(232) generates a touch point image by using the detected edge image. A coordinate calculating unit(233) calculates touch coordinates from the touch point image. The touch point image generating unit generates the touch point image by using the gradient direction and dimension of the edge image.
Abstract:
PURPOSE: A touch screen display apparatus and a method for driving the same are provided to recognize a touch point efficiently by using an optical sensor even when external and internal light conditions are not proper. CONSTITUTION: A panel includes a light emission element(210) and an optical sensor(220) that photographs an image of a touched object. A touch sensor(100) senses the touch of the object and is placed in the panel. When the touch sensing unit senses the touch of the object, a light emission control unit(310) activates the light emission element. The light emission control unit includes a touch measurement unit, a touch determining unit and a light signal generating unit.

Abstract:
An electronic display device is provided to prevent the crosstalk by blocking a region where left-to-right images and right-to-left images are mixed, reduce the driving frequency and power consumption, and prevent the leakage of light between the first and second electrodes. A display unit(100) selectively can display an one-dimensional(1D) image and 3D image, and display a left-eye image and right-eye image at the same time by dividing pixels for the left eye and right eye when displaying the 3D image. A scanning actuator(200) applies a selection signal, formed by the combination of gate on voltage and gate off voltage, to scanning lines by being connected to the scanning lines of the display unit. A data driving unit(300) applies a data signal for showing the grayscale to data lines(D1-Dm) by being connected with the data lines of the display unit. A controller(600) receives an input signal, a horizontal synchronization signal and a vertical synchronization signal from the outside, and then generates a scanning control signal(CONT1), a data control signal(CONT2), an image data signal(DR, DG, DB) and a barrier driving part control signal(CONT3).
