Abstract

PURPOSE:To directly indicate a position on a screen by arraying display picture elements and light receiving elements in lattice on the same screen. CONSTITUTION:In the display picture elements 2aa-2mn arrayed in lattice on the display screen 1, the corresponding display picture elements 2 emit light (discolor) to display according to character information and pattern information, etc. If the light receiving elements 3aa-3mn are arrayed in lattice on the display screen 1 and light beam is radiated to them from outside, the light receiving elements 3 sense it. When an operator watches the information displayed on the display screen and indicates an optional position on the screen, the indicated coordinate position on the display screen 1 can be directly indicated by radiating the light beam which the light receiving elements 3 can sense so as to make it detected.

Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明は文字情報や図形情報などをドツト表示する表示
装置に関し、特に表示画面上の座標位置を指定する座標
位置指定方式に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a display device that displays text information, graphic information, etc. in dots, and particularly to a coordinate position designation method for designating coordinate positions on a display screen.

〔従来の技術〕[Conventional technology]

カーソルの位置によって画面上の座標位置を指定する方
式がある。Conventionally, when displaying characters, figures, graphs, etc. on the screen and specifying any position on the display screen, a cursor is displayed on the screen and instructions are given using a pointing device such as a mouse.
Alternatively, there is a method in which the cursor is moved by instructions from the keyboard and the coordinate position on the screen is specified by the position of the cursor.

点がある。The above-mentioned method using a pointing device such as a cursor and a mouse or an instruction is an indirect instruction to move the cursor on the screen, so it takes time to move the cursor when specifying the location of the cursor and the location away from it. Disadvantages and disadvantages include the inability to directly indicate the position on the screen.

In the figure, there are display pixels 2aa to 2mn arranged in a grid on a display screen 1, and when the corresponding display pixels emit light or change color according to character information 1 graphic information, etc., character information 1 graphic information is displayed on the display screen. Display information etc. Further, on the display screen 1, there are light receiving elements 3a arranged in a grid pattern.
There are a to 3 mn, and when light is irradiated from the outside, the corresponding light receiving element is sensitive.

。When an operator looks at information displayed on a display screen and specifies a desired position on the screen, a device that emits light in a wavelength range to which a light receiving element is sensitive irradiates light to the corresponding position on the screen. At this time, the designated coordinate position on the display screen can be detected by detecting which of the light receiving elements arranged in a grid is sensitive to the irradiated light.
