Input device with display function
A liquid crystal module ( 1 ) includes a transparent panel ( 2 ) having a frame ( 3 ) projecting substantially perpendicularly from one surface thereof. The module also includes a flat panel display unit having a liquid crystal cell ( 6 ), a liquid crystal back light ( 7 ), and a liquid crystal back light unit ( 8 ), for example. The module further includes a flat sensor ( 9 ), such as a thin digitizer (a coordinate position inputting sensor). The frame is configured such that the flat panel display unit and the flat sensor can be readily housed and secured within a housing portion inside the frame.
1. An input device with display function comprising:
a transparent panel having an input-receiving surface and an opposite surface, the panel having a frame that is unitarily formed with the transparent panel and that is projecting substantially perpendicularly from the opposite surface to form a housing space defined by the frame;
a flat panel display unit housed in the housing space such that a display surface of the flat panel display unit opposes the transparent panel;
a flat sensor for detecting a position indicating operation performed on the input-receiving surface of the transparent panel, which is arranged adjacent to the flat panel display unit and is housed in the housing space,
wherein the flat panel display unit and the flat sensor are so housed in the housing space to be fixed to the transparent panel; and
a case including an opening and a hollow interior, the opening is configured to receive and house within the hollow interior the transparent panel having the frame defining the housing space in which the flat panel display unit and the flat sensor are fixedly housed,
wherein the frame is positioned spaced away from an outer edge of the transparent panel to project substantially perpendicularly therefrom to thereby define an end portion of the transparent panel that extends along a periphery of the transparent panel outside the frame, and
wherein the end portion of the transparent panel is fixed to a portion of the case that defines the opening to thereby secure the transparent panel having the frame defining the housing space, in which the flat panel display unit and the flat sensor are housed, in the case.
2. The input device according to claim 1 , wherein the flat panel display unit, the flat sensor, and the transparent panel are fixed to each other by bonding respective opposing surfaces together.
3. The input device according to claim 1 , further comprising a bezel, wherein the flat panel display unit and the flat sensor housed in the frame are fixed to the transparent panel by the bezel.
4. The input device according to claim 1 , wherein a light shielding area for shielding light is arranged on a surface of the transparent panel so as to cover an area above the frame projecting from the transparent panel.
5. The input device according to claim 1 , wherein the frame projecting from the transparent panel is bonded to the transparent panel.
6. The input device according to claim 5 , wherein the frame projecting from the transparent panel is bonded to the transparent panel with an adhesive.
7. The input device according to claim 6 , wherein the transparent panel is made of glass, and the frame is made of a resin material.
8. The input device according to claim 1 , wherein the frame projecting from the transparent panel is integrally formed with the transparent panel.
9. The input device according to claim 8 , wherein the transparent panel and the frame are integrally formed of a resin material.
10. The input device according to claim 1 , wherein an inner wall of the frame, in which the flat panel display unit and the flat sensor are housed, is formed in a taper shape, and the flat panel display unit and the flat sensor are positioned along the taper-shaped inner wall.
11. The input device according to claim 1 , wherein the flat sensor is located adjacent to another surface of the flat panel display unit opposite to the display surface such that the flat panel display unit is positioned between the transparent panel and the flat sensor.
12. The input device according to claim 11 , wherein the flat sensor is an electromagnetic induction type sensor which detects a position indicating operation performed with a pen-like position indicator on the input-receiving surface of the transparent panel.
13. The input device according to claim 12 , wherein the flat sensor is provided with a magnetic shield plate on a surface of the flat sensor opposite from the flat panel display unit.
14. The input device according to claim 1 , wherein the flat sensor is located adjacent to the display surface of the flat panel display unit such that the flat sensor is positioned between the transparent panel and the flat panel display unit.
15. The input device according to claim 14 , wherein the flat sensor is a capacitive type sensor which detects a position indicating operation performed by a finger of a user on the input-receiving surface of the transparent panel.
16. The input device according to claim 1 , wherein the flat panel display unit is selected from a group consisting of a liquid crystal display unit, an organic EL display unit, and a plasma display unit.
17. The input device according to claim 1 , wherein said portion of the case that defines the opening includes a recessed portion that is dimensioned to mate with said end portion of the transparent panel.
18. The input device according to claim 1 , which is a portable electronic device.
