Abstract

<P>PROBLEM TO BE SOLVED: To provide an input display system which is impressive without causing a feeling of strangeness because image quality (color purity, brightness and contrast) of a display screen is excellent due to the lack of a transmissive conductive film, etc., at the front of the display screen and because there is no difference in the image quality of the display screen between an input detection region and the other locations, and which consumes less power because power supply is not required for locations except the input detection region. <P>SOLUTION: This input display system 10 includes the display screen 11, a division indicator and an infrared transmission and reception module. The division indicator displays video information and input relevant information on the display screen 11 by dividing them. The display screen 11 on which the input relevant information is displayed is an input detection region 13. The infrared transmission and reception module transmits and receives infrared rays 35 and 36 in the input detection region 13 in the shape of a lattice to detect a position where the infrared rays 35 and 36 are interrupted. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

  The present invention displays television programs, guide maps, company advertisements, etc. on a large display screen, and allows a user to input and display desired information by touching a part of the input detection area of the display screen. The present invention relates to an input display system.

  Conventionally, a small window for input (input detection area 52) called a “child window” is displayed on a part of the screen of the large screen display 51 with a touch panel as shown in FIG. An input display system 50 that performs an operation is known (for example, Patent Document 1). The input detection area 52 (child window) is an independent small rectangular display area in the display.

  Such an input display system 50 can easily input or display information simply by a user touching the input detection area 52. Therefore, such an input display system 50 is expected for uses such as a two-way communication large television set and a digital signage.

  In the conventional input display system 50, a resistive film type or capacitive type touch panel (input detection means) using a transparent conductive film is usually arranged on the entire screen.

  The reason why the transparent conductive film is arranged on the entire screen is that, if the transparent conductive film is arranged on only a part of the screen, the transmittance and refraction of the region where the transparent conductive film is arranged and the region where the transparent conductive film is not arranged are arranged. This is because the display quality of the screen is not uniform because the rates differ.

  For this reason, for example, a transparent conductive film must be installed in a region where there is no possibility of performing a touch operation because it is in a position where it cannot be reached, as in the region where a touch operation is performed.

  Installing an expensive transparent conductive film in an area where there is no possibility of performing a touch operation increases the cost. Furthermore, if power is supplied to a transparent conductive film in a region where there is no possibility of touch operation in the same manner as the transparent conductive film in a region where touch operation is performed, wasteful power consumption occurs.

JP 2006-018348 A

  In the conventional input display system 50, a resistive film type or capacitive type touch panel (input detection means) using a transparent conductive film must be arranged on the entire screen including an area where there is no possibility of performing a touch operation. Don't be.

  Installing an expensive transparent conductive film in an area where there is no possibility of performing a touch operation increases the cost. Furthermore, if power is supplied to the transparent conductive film in a region where there is no possibility of performing a touch operation, the power consumption of that portion is wasted.

The gist of the present invention is as follows.
(1) The input display system of the present invention includes a display screen, a split display, and an infrared transmission / reception module. The split display divides and displays video information and input related information on the display screen. The display screen on which the input related information is displayed is set as the input detection area. The infrared transmission / reception module transmits / receives infrared rays to / from the input detection area in a grid pattern and detects a position where the infrared rays are blocked.
(2) In the input display system of the present invention, the infrared transmission / reception module includes a light emitting unit and a light receiving unit in the x direction on two opposite sides of the display screen. The infrared transmission / reception module includes a light emitting unit and a light receiving unit in the y direction on the other two opposite sides of the display screen.
(3) In the input display system of the present invention, the light emitting unit is formed by an infrared light source and an optical waveguide optically coupled to the infrared light source. The optical waveguide divides infrared rays from the infrared light source to generate a plurality of light beams.
(4) In the input display system of the present invention, the light receiving unit is formed by an optical waveguide that receives an optical signal and a plurality of photoelectric conversion elements optically coupled to the optical waveguide.

  Since the input display system of the present invention does not have a transparent conductive film having a low transmittance on the front surface of the display screen, the image quality (color purity, brightness, contrast) of the display screen is good. In addition, since there is no difference in the image quality of the display screen between the input detection area and other places, the display screen is not uncomfortable and looks good. Furthermore, since it is not necessary to supply power to places other than the input detection area, power consumption is low.

  The display screen 11 is controlled by an image signal from the display unit 26a for displaying video information. The input detection area 13 is controlled by the image signal from the display section 26b for displaying input related information.

[Infrared transceiver module]
As shown in FIG. 4, the infrared transmission / reception module 14 used in the present invention includes, for example, a light emitting unit 31 and a light receiving unit 32 in the x direction on two opposite sides of the display screen 11. The infrared transmission / reception module 14 includes a light emitting unit 33 and a light receiving unit 34 in the y direction on the other two opposite sides of the display screen 11. Furthermore, the infrared transmission / reception module 14 is provided with those drive parts (not shown).

  As shown in FIG. 4, the infrared transmission / reception module 14 used in the input display system 10 of the present invention transmits and receives the infrared rays 35 in the x direction and the infrared rays 36 in the y direction in a lattice pattern near the surface of the display screen 11. The input detection area 13 is formed.

  The light emitting units 31 and 33 are formed by arranging a plurality of infrared light sources (light emitting diodes or semiconductor lasers) in a line at regular intervals. Alternatively, the light emitting units 31 and 33 are formed by an infrared light source and an optical waveguide optically coupled to the infrared light source. In this case, the optical waveguide divides the infrared rays from the infrared light source to generate a plurality of light rays.

  The light receiving sections 32 and 34 are formed by arranging a plurality of photoelectric conversion elements (CMOS and CCD) that receive an optical signal and convert it into an electric signal in a line at regular intervals. Alternatively, the light receiving portions 32 and 34 are formed by an optical waveguide that receives an optical signal and a plurality of photoelectric conversion elements optically coupled to the optical waveguide.

  When the infrared rays 35 and 36 passing through the input detection area 13 are blocked by a finger or a pen, the intensity of the infrared rays 35 and 36 at the blocked position is reduced. By detecting this, the infrared transmission / reception module 14 can detect the position (input coordinates) of a finger or a pen.

  In the input display system 10 of the present invention, the input detection area 13 is formed in a part of the display screen 11, and is preferably formed in the lower right of the display screen 11. The ratio of the input detection area 13 to the display screen 11 is preferably 10% to 60%, and more preferably 10% to 30%.

  Since the input display system 10 of the present invention does not have a transparent conductive film having a low transmittance on the front surface of the display screen 11, the image quality (color purity, brightness, contrast) of the display screen 11 is good. In addition, since the image quality of the display screen 11 is not different at all between the input detection area 13 and other places, it does not feel strange and looks good. Further, since the light emitting units 31, 33 and the light receiving units 32, 34 are not provided in places other than the input detection area 13, it is not necessary to supply power for input, and power consumption is low.

  The use of the input display system 10 of the present invention is not particularly limited, but it can be suitably used for a two-way communication large television, a digital signage, and the like.
