Problems solved by technology

Therefore, since the light of the backlight is absorbed by the LCD or the sensor, there is a problem that a sufficient amount of light cannot be obtained.
In addition, the sensor needs to be made of a light-transmitting material, which also poses a problem in terms of cost

Abstract

A coordinate input unit is composed of a sensor as a means for detecting a manipulating state on a manipulation surface A manipulated by a coordinate indicator and a front light as an illumination means disposed on the sensor to illuminate the manipulation surface A. When the manipulation surface of the coordinate input device is illuminated, the light emitted from an LED is transmitted in a light introduction plate, emerged from a prism surface, changes its direction by being reflected on a reflection plate, and is directed to the manipulation surface. With this operation, the manipulation surface is illuminated.

Description

technical field [0001] The present invention relates to a coordinate input device and a terminal device with the coordinate input device, in particular to a coordinate input device with a light emitting function and a terminal device with the coordinate input device. Background technique [0002] Currently, a coordinate input device called a touch panel is mounted on a portable computer terminal device such as a notebook computer. The touch panel is a pointing device for operating the cursor and pointer displayed on the screen of the terminal device in the same way as a mouse. Move the coordinate value or contact point, and operate the cursor and pointer according to the displacement of the coordinate value. [0003] In such a coordinate input device, a sensor is made of a translucent thin plate, and a color LCD panel with a backlight is arranged below the sensor to illuminate the operation surface. [0004] [Patent Document 1] (Japanese) Unexamined Patent Publication No. ...
