たは遮蔽物をおく。According to the present invention, a flat display is formed by using heaters arranged in a matrix, and has the advantage that a conventional fluorescent material can be used together with a simple structure. . The specific method is as follows. , Point heaters arranged in a matrix, discharge gas,
For example, mercury vapor of several mmHg is sealed. By applying a voltage corresponding to the luminance at that point to the heater, ultraviolet rays are generated. (Heating by matrix driving or other means), this ultraviolet light is collided with a flat or well-shaped fluorescent substance. Place a filter or shield so that the direct term of the heater is not visible.

Place a heater material such as tungsten at the intersection of X and Y,
The surface is treated so that thermal electrons are easily emitted. Heat is generated by a power pulse corresponding to the intersection of X and Y. Assuming that the refresh rate of the screen is 60 Hz, the heating heater only needs to have a time constant of about 1/120 seconds for heating and heat removal.

てくる。In order to further reduce the size of the display element, a matrix cathode is formed by arranging the display elements in a matrix using a mechanism of a thermal head which is used in a thermal printer or the like. However, it is necessary to make the temperature higher than that for printers (about 400 ° C.).
