摘要： A liquid crystal panel with built-in sensors 11 includes, in a pixel array 17, a plurality of pixel circuits 1 and a plurality of optical sensors 2 which are arranged two-dimensionally. Infrared light transmitting filters 3 that allow infrared light to pass therethrough and cut off visible light are respectively provided in paths of light entering the optical sensors 2. Accordingly, an image obtained by the optical sensors 2 is prevented from being influenced by visible light included in outside light or backlight light and thus a touch position is detected with high accuracy, based on an image that is not influenced by visible light included in a large amount in outside light or backlight light. Instead of the infrared light transmitting filters 3, a light-shielding film having the same property 3 may be used.

摘要： A liquid crystal panel 11 with built-in sensors includes, in a pixel array 18, a plurality of pixel circuits and a plurality of optical sensors arranged two-dimensionally. When the liquid crystal panel 11 is formed of CG silicon, the light receiving sensitivity of the optical sensor is high for blue light but becomes low for red or green light. A display data processing unit 12 corrects a gradation having a value that is less than or equal to a predetermined value, to high for a blue component contained in display data D1. The display data processing unit 12 corrects only data displayed in a recognition area set in a display screen out of the blue component. Thus, even when the display image is dark, it can be converted to an image easy to recognize, a touch position can be detected properly irrespective of the display image, and a change of the display image by correction can be limited to the change of a specific color in a specific area.

摘要： A liquid crystal panel with built-in sensors 11 includes, in a pixel array 17, a plurality of pixels 1 and a plurality of optical sensors 2 which are arranged in a row direction and a column direction. The optical sensors 2 are provided to be associated with pixels 1 in every other row (e.g., to be associated with pixels 1 in even rows). A panel drive circuit 16 performs one-line inversion drive and reads signals based on the amounts of received light, from the optical sensors 2. Since the outputs from the optical sensors 2 change in the same direction due to the influence of display data, stripe noise resulting from the switching of the polarities of voltages written into pixel circuits 3 is prevented from occurring in an image generated based on the outputs from the optical sensors 2.

摘要： A display panel with built-in optical sensors is provided that can accurately remove a noise component in an imaging signal of an image pick-up sensor in a display region without being influenced by distance from a heat source or distance from a sensor output terminal. The display panel with built-in optical sensors has an active matrix substrate having a pixel region in which pixels are disposed in a matrix, and is configured such that optical sensors are formed in at least a portion of the pixel region. Among the optical sensors in the pixel region are image pick-up sensors (12S) and light-shielded sensors (12B) that are shielded from light. The display panel with built-in optical sensors further includes a correction circuit (4) that corrects sensor output of the image pick-up sensors (12S) with use of sensor output from the light-shielded sensors (12B).

摘要： Provided is a display device characterized in that a display area can be prevented from appearing darker when the position of light-shielding sections are moved, while the control of voltages applied to electrodes is simplified. In the case where electrodes to which a specific voltage is applied are changed from a first electrode group (e.g., 52a) to a second electrode group (e.g., 52b, 58a, 58b), the voltage applied to the first electrode group is switched from the specific voltage to a reference voltage first, and thereafter, the voltage applied to the second electrode group is switched from the reference voltage to the specific voltage.

摘要： In a display device with optical sensors, a recognition processing portion (22) performs recognition processing on a scan picture generated by optical sensors (2), and calculates a position. A mode control portion (24) determines whether or not the mode is standby so that the recognition processing portion (22) is stopped from operating. At the time of transition to the standby mode, decimated image memory (25) stores a decimated image with a decreased number of pixels. The mode control portion (24) performs pixel-by-pixel comparison between the stored decimated image and a decimated image supplied anew, and exits the standby mode when the number of pixels whose difference in pixel values is greater than or equal to a first threshold is greater than or equal to a second threshold. Here, the first and second thresholds are appropriately set in accordance with an ambient luminance L from a luminance sensor (20), and therefore, any change in the image can be accurately distinguished from noise, thereby preventing the standby mode from being or not being cancelled by mistake.
