Abstract

PURPOSE:To increase the accuracy and fineness of a cathode-ray tube for a display light source, and realize a finer picture by providing the cathode-ray tube with the same number as the number of plural multicolor phosphor layers of electron guns in positions corresponding to said plural multicolor phosphor layers. CONSTITUTION:The inner wall of the face plate 12 of a light-source cathode-ray tube 10 is coated with a phosphor layer 11. The phosphor layer 11 consists of a red-color emitting, a green-color emitting and a blue-color emitting phosphor layer 11R, 11G and 11B which are adjacent to each other at an angle of 120 deg. to each other. At the other end of the cathode-ray tube 10 three electron guns 13R, 13G and 13B are arranged at an angle of 120 deg. to each other correspondingly to the above three differently-colored phosphor layers 11R, 11G and 11B. The electron gun 13R discharges a non-focusing flat electron beam 14R, which irradiates and stimulates a red-color emitting phosphor layer 11R so as to produce a red light spot 15R.

Conventionally, giant display devices used to display advertising images, etc., on electronic display boards at baseball stadiums, building roofs, walls, etc., have traditionally been made by arranging a large number of colored light bulbs and selectively blinking them.

To give some examples, for example, in the case of a light bulb, the light is obtained by the red heat of the filament, so the color of the light emitted is mainly red or sandalwood. For this reason, it was common practice for the above-mentioned light bulbs to emit a large amount of colored light, for example evening or green.

The distance is extremely low at less than 1 m, and in addition, the applied current and emitted light intensity are not linear, and the emitted light color itself changes depending on the applied current. Even when I served it, there was a lot of trouble.

Furthermore, the light bulbs used in such giant display devices generally have a power of 10W or more, so in a giant display device where tens of thousands or more are lined up, the power generated by the light bulbs and the heat generated by the light bulbs are significant. There were some problems.

This can be done by modulating the electron beam from the electron gun (5) in G) and (IB). In addition, the frequency response of the amount of light is determined by the afterglow time of the phosphor layer (3) used, but generally the afterglow time of the phosphor of the phosphor layer (3) used in this type of display is Since the time is 1 ms or less, there is no problem in image switching of 5QHg or more, the electron beam can be easily modulated, and intermediate tones can be precisely reproduced.
