    摘要: A light-sensitive (i.e., touch-sensitive) display device that requires less circuitry than the currently available light-sensitive display devices is presented. Unlike the currently available devices, which require at least two switching elements and a capacitor to implement a photosensitive switch, the invention only requires one switching element. The device of the invention includes a substrate with a plurality of scan lines, a plurality of read-out lines, a power line, and an array of photosensitive switches formed thereon. The scan lines and the read-out lines extend in directions that are substantially perpendicular to each other, forming pixels. One photosensitive switch is formed in each pixel, and each photosensitive switch has one light-sensitive transistor. The transistor connects the power line to one of the read-out lines in response to sensing incident light.

    摘要: A touch position detecting method, a device using the method, and a touch screen display device having the device are disclosed. A touch sensing unit senses a touch event and outputs a sensing data. A reference update unit updates a reference data with an n-th frame sensing data provided from the touch sensing unit, based on a predetermined update signal. A position detecting unit detects the touch position by using the reference data and an (n+i)-th frame sensing data from the touch sensing unit. Therefore, the touch position is easily detected by determining a difference between the reference data and the sensing data at a certain time.

    摘要: Disclosed is a transmissive and reflective type LCD. In the LCD, a second substrate faces a first substrate. A liquid crystal layer is formed between the first substrate and the second substrate. A first polarizing plate is formed on an outer surface of the first substrate. A second polarizing plate is formed on an outer surface of the second substrate. A backlight is arranged for irradiating incident light onto the polarizing plate. A transparent transflective film is arranged between the first polarizing plate and the backlight for partially reflecting and partially transmitting the incident light. The transparent transflective film includes at least a first layer and a second layer, the first and second layers having different refractivity indexes from each other and are alternatively stacked. By a restoring process occurring between the transflective film and the backlight, a predetermined amount of the incident light is transmitted through the transflective film repeatedly, so that transmissivity and light efficiency are enhanced.
