Ｒ電力がＣＲＴ方式の約５倍、応答特性がＣＲＴ方式で
１ミリ秒以下であるに対して５０乃至１５０ミリ秒と遅
いという欠点がある。The CRT method is superior to the light bulb method in terms of white temperature, brightness of colors, amount of power per pixel, and responsiveness, but it has the drawback of not being able to achieve high luminance. Also, although the light bulb method is superior in terms of picture element detail and brightness,
It has the disadvantage that the R power is approximately five times that of the CRT method, and the response characteristic is slower at 50 to 150 milliseconds, compared to 1 millisecond or less in the CRT method.

The cathode electrode 5 is heated through T, the starter ST is activated, a high voltage pulse is applied between the anode electrode 4C and the cathode electrode 5, and discharge is started in the discharge path 3C.
For example, blue light is emitted. Next, select selection switch S
When W is switched and the discharge path 3b is switched on, the discharge path 3b immediately discharges (because the cathode electrode 5 has already been heated and is fully ready to emit thermionic electrons, and the common space near the cathode electrode 5). Since the seeds of charge for discharge remain in the discharge path 3b, it is easy to start without the starter ST.)
Then, green light is emitted. Continue to select selection switch S
When W is switched and the discharge path 3a is switched on, it discharges easily in the same way as the discharge path 3b, producing a red discharge.

Because it uses a tube body, it does not become bulky and can provide a thin, flat display surface when arranged as a display device, making it convenient to install on a wall. The airtight space is partitioned into a plurality of parts to form independent discharge paths within the airtight space, one end of each discharge path is closed to provide each independent electrode, and the other ends of each discharge path are placed adjacent to each other in open communication with each other. At the same time, a common electrode is provided in one continuous discharge space in the I, and phosphors of different luminescent colors are coated on at least one surface of the inner surface of the tube of each discharge path individually or for each group, and a low pressure is applied in the airtight space. At least one of a rare gas and a metal vapor gas is enclosed, and a lighting control means is provided externally for controlling the light emission of the discharge paths divided by the different phosphors individually or for each group, and the color toning is controlled individually or as a whole. This allows for the high luminous flux and highly efficient color display that characterize discharge lamps, and the fact that it has a common space within a single light source tube and is designed to split multiple discharges. For example, even if one discharge has a high load and high 2 stars, other parts of the space are maintained at a relatively low temperature, which is extremely advantageous in terms of efficiency, especially in the case of mercury discharge.Furthermore, the overall current is constant and continuous. This has the effect that electrode (cathode electrode) wear is small, which makes it easier to save life, and the input current waveform is 7 lats, so problems with electrical noise and input usage are small.
