Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a luminous body that emits light by gas discharge and a luminous device using the luminous body.

2. Description of the Related Art In recent years, in places where the public gathers, such as stadiums and event venues, live displays are displayed on ultra-large displays of several meters in size. With this type of display becoming more common, there is a demand for a larger and less expensive display capable of displaying color moving images.

[0003]

2. Description of the Related Art An actual self-luminous ultra-large display is formed by arranging light sources such as a cathode ray tube and a light emitting diode (LED) vertically and horizontally. Usually, the total number of light sources is hundreds of thousands or more, and assembling the display requires a lot of labor and cost.

On the other hand, a 42-inch PDP (plasma display panel) has been put to practical use as a large-sized self-luminous display having a single structure. PDP is
A thin display device having a structure in which a discharge space is sandwiched between a pair of glass substrates, and has a surface discharge type or counter discharge type electrode matrix. In the surface discharge type, main electrodes forming an electrode pair (anode and cathode) for discharge are arranged in parallel, and a sub-electrode called an address electrode is arranged to cross the main electrode. In the opposed discharge type, the main electrodes are distributed to the front and rear glass substrates and are arranged in an intersecting manner. The sub-electrode is unnecessary in the opposed discharge type. In the classification according to the driving mode, the PDP is roughly classified into an AC type and a DC type. In the AC type, a dielectric is provided between the main electrode and the discharge space, and a memory function by charging the dielectric is used. If the charge amount of the cells arranged vertically and horizontally is controlled in binary, even if a voltage is applied in common to all the cells thereafter, the cells whose charge amount is less than the predetermined value do not emit light. In the DC type, basically, a voltage is applied only to the cell that emits light. Regardless of the AC type or the DC type, in a PDP, a display color different from the emission color of the discharge gas can be obtained by providing a phosphor layer inside. The surface discharge type is advantageous in preventing the deterioration of the phosphor layer. A PDP for color display having three types of phosphor layers can also be used as a backlight of a liquid crystal screen by causing the entire light emitting surface to emit white light.

Conventionally, an ultra-large display utilizing the light emission principle of a PDP has been proposed by the present applicant as a "large gas discharge display panel".
No. 03187 discloses it.

The ultra-large display proposed in this proposal is a collective structure in which a plurality of elongated light-emitting modules corresponding to a PDP having one row (or number of columns) are arranged in one direction and integrated. It has the following advantages over the display. Since they are arranged in one direction, the number of assembling steps can be reduced as compared with the case where they are arranged in two directions (length and width). In particular, in the case of LEDs, since the production unit is one picture element, hundreds of thousands to several million picture elements must be formed, which increases the cost. Since the cells for one row are integrally formed at a time, the weight and cost are lower than a set of independent cathode ray tubes for each cell. Higher brightness than LED.

On the other hand, the screen size (the number of rows and the number of columns) is determined by the size of the glass substrate in the above-described single-piece PDP, while the proposed collective display has an arbitrary number of light emitting modules by increasing or decreasing the number of light emitting modules. The number of rows (or the number of columns) can be displayed. Although the number of columns (or the number of rows) depends on the length of the light emitting module, the length of the light emitting module is much easier than that of a large PDP. Ultra-large glass substrates are less feasible from the viewpoint of factory equipment and transportation. In other words, when trying to produce a large display in a single configuration, a glass plate larger than the screen size must be handled, and a size of 100 inches or more is not practical. The upper limit of the display dimensions (pixel size, screen size, etc.) that can be produced by the production equipment is determined. In order to produce a large-sized display beyond that, production equipment must be newly constructed. On the other hand, if the production unit is a line, it is easy to assemble and a design change according to the dimensions of the display can be made without a significant change in production equipment. Therefore, displays of various sizes can be realized at low cost.

[0008] A conventional light emitting module is formed of a glass tube having a rectangular cross section, and is arranged next to another light emitting module such that two opposing sides of the square are in the arrangement direction. Of the four side surfaces constituting the outer peripheral surface of the glass tube, a band-shaped main electrode extending over the entire length is fixed to one side surface in the arrangement direction, and a plurality of main electrodes are arranged along the length direction on the remaining side surfaces in the arrangement direction. Are fixed at equal intervals. That is, the electrode configuration is a counter discharge type, and the glass tube can partially emit light by selectively applying a voltage to the strip-shaped main electrode.

[0009]

In a display using the above-described light-emitting module, the main electrode in a strip shape and the main electrode in a strip shape of each light-emitting module are opposed to each other across the width of a glass tube. The main electrodes of adjacent light emitting modules are close to each other via a thin insulating layer. For this reason, there has been a problem that a discharge starting voltage is high and it is difficult to secure a sufficient voltage margin for stabilizing light emission control. When the arrangement interval of the light emitting modules is increased in order to prevent unnecessary discharge between adjacent light emitting modules, the pixel density of the screen is reduced.

[0010] In addition, a wiring operation performed after arranging and integrating a large number of light emitting modules, that is, an operation of connecting strip-shaped main electrodes between adjacent light emitting modules to complete an electrode matrix of a screen size is extremely troublesome. Was. This is because there is a need for advanced conductive connection technology that eliminates contact failures and minimizes line resistance.

Further, in the case where the light source is used as a planar monochromatic light source, it is necessary to connect the electrodes in the same manner as in the display to form an electrode matrix, or to connect all the strip-shaped main electrodes to make them common. . Either way, the number of strip-shaped main electrodes is the same as the number of cells, so the operation is troublesome.
Even when one light emitting module is used alone as a linear monochromatic light source, it is necessary to connect all the strip-shaped main electrodes arranged in one direction.

An object of the present invention is to provide a highly reliable luminous body that emits light by gas discharge and that can be partially luminous by an external electrode and can be used as a linear light source as it is. The second object is to realize a collective display which has high reliability of light emission, is inexpensive, can be easily assembled, and can display a matrix.

[0013]

In the present invention, a plurality of electrodes (main electrodes) are arranged in parallel inside or outside a long and narrow vessel surrounding a discharge gas space to provide a surface discharge type electrode pair. Here, “elongated” is defined as “the length is 10 times or more the width”. Since it is of the surface discharge type, the arrangement interval of the main electrodes can be made smaller than the width of the container, and the firing voltage between the main electrodes can be reduced. Thereby, the margin of the applied voltage is expanded, and the reliability of the light emission control is enhanced. A third electrode (sub-electrode) for partial light emission is directly attached to such a vessel, or a sub-electrode is provided on a support separate from the vessel without being directly attached. In the case of performing a matrix display, a plurality of containers are arranged in one direction to assemble a planar light-emitting body, and a support of the sub-electrode is combined with the light-emitting body such that the sub-electrode crosses the main electrode. In the electrode arrangement configuration in which each of the plurality of vessels is provided with an electrode pair extending in the length direction, the sub-electrode and the main electrode may be close to each other so that the firing voltage between them becomes a value within a practical range, No conductive connection between each of the plurality of vessels and the support of the sub-electrode is required.

The arrangement direction of the light emitting modules is not limited to the horizontal direction H, and the light emitting modules may be arranged in the vertical direction V.
However, when assembling a screen that is generally long in the horizontal direction H, it is advantageous to arrange the light emitting modules in the horizontal direction H. This is because the light emitting module may be shorter than the electrode module, and the display is generally lower in price.

In assembling the display, a light-emitting unit in which a plurality of light-emitting modules are integrated may be prepared in advance, and the plurality of light-emitting units may be arranged at the installation location of the display.

For forming the phosphor layer, a printing technique cultivated by PDP is suitable. It is possible to efficiently form a uniform phosphor layer extending over the entire light emitting surface by printing. However, the emission color of the light emitting module does not need to be a single color.
Phosphor layers of each color of R, G, B may be arranged in a predetermined order on each light emitting module in the length direction.

When the main electrodes X and Y are strip-shaped, they can be arranged so that their main surfaces face each other. For example, the main electrodes X and Y can be arranged separately on opposing inner walls of a vessel having a rectangular cross section.

A light emitting cell Cs capable of individually controlling light emission by gas discharge between the light emitting cells Cs is formed.

In the above configurations of FIGS. 15 to 18,
Since the sub-electrodes Ap to s are arranged in the gas space, the main electrode is used to generate an address discharge for selecting individual cells in comparison with the configuration of FIGS. 1 to 14 arranged on the outer surface of the vessel. The voltage applied between the electrode and the sub-electrode can be reduced. In addition, surface discharge between main electrodes (main discharge to secure luminance)
Although the applied voltage for causing the voltage increase becomes higher, the effect is smaller than when the applied voltage of the address discharge is increased.
In other words, while the applied pattern changes depending on the display content while the address discharge is of the DC type, the applied pattern of the main discharge is of the AC type and the applied pattern is fixed. An increase in power can be suppressed. An increase in the applied voltage of the address discharge causes an increase in the load on the drive system and an increase in power consumption.

In the matrix display, if the screen resolution (the number of pixels) is fixed, it is desirable that the number of scanning lines be smaller. This is because the time required for line-sequential addressing is shortened, and the number of divisions in gradation reproduction for dividing a frame into a plurality of sub-frames having different luminance weights can be increased to improve gradation. In the case where one light emitting module emits one color, a color display of 1
Three or more light emitting modules correspond to pixels. Therefore, normally, the number of cells in the arrangement direction (here, the horizontal direction) of the light emitting modules on the screen is larger than the number of cells in the vertical direction. When a conventional driving method of a PDP, which is a single-unit display using a main electrode as a scan electrode, is applied to thereby use an existing drive circuit device (integrated circuit), FIG. 15 is used in view of reducing the number of scanning lines. ~ Figure 1
The configuration of FIG. 8 is more advantageous than the configuration of FIG.
