Abstract: A head mounted display system includes an infrared sensor generating an infrared image, an image processor measuring a position of a user pupil based on the infrared image and generating image source based on the position of the user pupil, and an organic light emitting display device displaying an image corresponding to the image source. The organic light emitting display device includes a display panel and a panel driver. The display panel includes a plurality of infrared pixels disposed in an infrared emission region, the infrared pixels emitting infrared light, and a plurality of display pixels disposed in a display region, the display pixels emitting visible light. The panel driver provides driving signals to the infrared pixels and the display pixels.

Abstract: A display device includes a first display region, a second display region, a first lens, and a second lens. The first display region includes a first pixel subset and may display a first image. The first image includes a first sub-image corresponding to the first pixel subset and smaller than the first image. The second display region neighbors the first display region, includes a second pixel subset, and may display a second image. The second image includes a second sub-image corresponding to the second pixel subset and smaller than the second image. The second pixel subset is not identical to the first pixel subset. The first lens may show the first sub-image without providing the entire first image. The second lens may show the second sub-image without providing the entire second image when the first lens shows the first sub-image.

Abstract: An image processor includes a scaling unit configured to output converted data by resizing first image data; and a rendering unit configured to receive second image data, to output rendering data by rendering the second image data, and to calculate a target rendering data value based on data values corresponding to a first block of M*N among the second image data, where each of M and N is an integer greater than or equal to 2. Here, the second image data is the converted data, or the first image data is the rendering data.

Abstract: A touch sensor device includes first electrode patterns arranged in a first direction and physically separated first electrode cells; second electrode patterns arranged in a second direction crossing the first direction and includes physically separated second electrode cells; first touch signal lines connected to the first electrode cells; second touch signal lines connected to the second electrode cells; and a touch sensor controller connected with the first touch signal lines and the second touch signal lines. The first electrode cell and the second electrode cell adjacent in the first direction form a channel for generating position information by a mutual capacitive method. The touch sensor controller stores a ghost table including a ghost ratio for each channel for a touch position, and removes a ghost from measured touch data by using the ghost table to generate final touch data.

Abstract: A method for detecting noise includes determining whether a data value of a candidate pixel in a predetermined region of an image matches a first dynamic false contour (DFC) candidate value, determining whether a data value of at least one pixel adjacent to the candidate pixel matches a second DFC candidate value, and changing the data value of the candidate pixel the prior two determinations. The data value of the candidate pixel may be changed to a value in a lookup table. The first and second DFC candidate values may also be stored in one or more lookup tables.

Abstract: A common sub-expression elimination method for simplifying hardware logic of a hardware filter circuit by eliminating a common sub-expression included in a plurality of sub-expressions is provided. Each of the sub-expressions includes a corresponding two or more of inputs constituting a plurality of coefficients used by the hardware filter circuit. The method is implemented on a computing device and includes: identifying for each coefficient of the plurality of coefficients, a combination of the inputs constituting the coefficient; counting occurrences of the sub-expressions in each of the coefficients; identifying one or more of the sub-expressions having a maximum one of the counts and including the corresponding two or more of the inputs; selecting one of the one or more of the sub-expressions as the common sub-expression; eliminating the common sub-expression; and repeating these steps to eliminate more of the sub-expressions common to multiple ones of the coefficients.
