  • Patent number: 9507148
    Abstract: 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.

  • Publication number: 20120176342
    Abstract: In an LED unit (23U), a plurality of P (an integer of three or more) units of LEDs (23) are placed so as to be mutually spaced apart while facing a line sensor (22C), and to supply light by way of being lit sequentially to a placement space (MS) to be lit. A position detection unit (12) uses a triangulation method to detect the positions of one or more objects, such as fingers, on a coordinate map area (MA) from the changes in the amount of light received according to P or more shadows at a line sensor unit (22U) that have been generated by light of the plurality of LEDs (23) illuminating at most P?1 objects placed in the placement space (MS).

  • Publication number: 20110157097
    Abstract: A coordinate sensor (10) includes at least two line sensors (1) that are disposed in x-axis and y-axis directions, and right-angle prisms (2) each of which changes a light path of light that has passed through an image display region of a liquid crystal panel (20). Each of the line sensors (1) is disposed outside the image display region and has a light-receiving surface (1a) parallel to an image display surface of the liquid crystal panel (20). The right angle prisms (2) cause light which travels in the x-axis and y-axis directions and which has passed through the image display region to be guided to the light-receiving surfaces (1a) of the line sensors (1). The coordinate sensor (10) receives the light which has thus passed through the image display region of the liquid crystal panel (20) so as to detect a coordinate, on the image display region, that is indicated by an object to be detected such as a finger.
