[Prior Art] In recent years, the liquid crystal display panel (LCD pane 1) has gradually replaced the conventional cold cathode tube (CCFL) to become the mainstream of the display. However, the liquid crystal display panel itself does not have the function of emitting light, so it is below the liquid crystal display panel. A backlight module must be provided to provide a light source to achieve the display function. Although the light source of the arm light module of the currently commercially available TV is composed of a plurality of cold cathode tubes (CCFLs), light is also used. A diode (LED) is used as a light source. However, since (^ or 1) is a linear or point-like light source, it is necessary to obtain a uniform light-emitting wire by the diffusion plate in the backlight module. The development of technology and the evolution of technology, the liquid crystal display panel riding wealth (four) is large, the higher the uniformity of the backlight module lighting requirements, the flat fluorescent lamp made of ECG listening components, not only has good efficiency And uniformity, and enough to provide a large area of the surface light source, more in line with the requirements of the backlight module for light uniformity' and the flat fluorescent lamp is widely used in liquid crystal display In addition to the backlight of the board, it is also used in other applications such as advertising light boxes. The flat fluorescent lamp is a kind of electroluminescent light-emitting element (pl_a m emiUlng device), which is mainly used after the electron is emitted from the cathode. Moving between the cathode and the anode, and colliding with the pure crucible (inert post) in the discharge space (仏化(10)space), 099127224 Form No. A0101 Page 4 of 23 0992047827-0 201209349 to ionize and excite the gas The plasma is formed, and the ex cited state atom in the plasma returns to the ground state in the form of ultraviolet (Ultra-Violet), and the ultraviolet radiation emitted by the plasma further stimulates the planar light source. Phosphor to generate visible light. Please refer to Figure 1A for a cross-sectional view of a conventional structure of a planar fluorescent lamp. The planar fluorescent lamp is mainly composed of a gas discharge chamber 100 and fluorescent light. The body 102, the discharge gas 104, the internal electrode 106, and the dielectric layer 1〇8 are formed, wherein the gas discharge chamber 1 is composed of a lower substrate 100a, an upper substrate 10b, and a side strip 100c. The 〇10〇c is disposed between the lower substrate 10a and the upper substrate i〇0b, and is connected to the edges of the lower substrate 100a and the upper substrate 10b to form a sealed cavity, and the internal electrode 106 is disposed. On the lower substrate 1 , these internal electrodes 106 are usually covered with a dielectric layer 1 〇 8 to protect the internal electrodes 1 〇 6 from being damaged by ion impact, and filled in the gas discharge chamber 1 〇〇 The discharge gas 104 is, for example, Xe, Ne, Ar or other inert gas, and the phosphor 102 is disposed on the inner wall of the gas discharge chamber. Q [0004] At present, the fluorescent material in the flat fluorescent lamp, the conventional printing technology is mainly to first mix the fluorescent powders (for example, red, green, blue fluorescent powder) to be printed in a specific ratio. Well, after adding a specific solvent, stirring and mixing into a uniform phosphor, using a screen printer and a screen, a specific film thickness of the phosphor is printed on the glass substrate, and then baked at a high temperature. Get rid of the solvent and leave the fluorescent material. Since the fluorescent material is prepared by previously mixing various kinds of fluorescent powders of different luminescence spectra, the particle size and specific gravity of the fluorescent powders of different colors are different, although the luminaire of this method has been fully mixed before printing, and finally left. The uniformity on the glass substrate 099127224 Form No. A0101 Page 5 / 23 pages 0992047827-0 201209349 However, it is easy to exhibit unevenness due to factors such as particle size and specific gravity, as shown in Figure 1B. The large fluorescent powder is easy to settle on the bottom layer, and it is less likely to be exposed to ultraviolet light, causing the spectrum of the light source to perform as expected. In this way, it is impossible to provide a flat fluorescent lamp that effectively produces optical characteristics such as color rendering index and color temperat ure, and if it is desired to develop a flat fluorescent lamp of different color rendering properties, it is absolutely necessary. With the development of fluorescent materials, it is often costly and not easy to succeed. Therefore, the present invention provides an effective arrangement and printing method of a fluorescent material for a flat lamp to improve the color rendering of a flat lamp. [0005] [0007] [0007] A fluorescent lamp according to the prior art disclosed in the prior art Light material printing technology, because the uniformity after printing will be affected by factors such as the particle size and specific gravity of the phosphor, and it will easily appear uneven, and the fluorescent powder with a large specific gravity will easily settle on the bottom layer. Under the ultraviolet light, the spectrum of the light source is not as good as expected. In addition to the development of flat fluorescent light with different color renderings, it is very costly and difficult to succeed in the development of fluorescent materials. Therefore, one of the main objects of the present invention is to provide a printing method for a glare material of a flat lamp, which is a stencil printing process technology, which prints a knives of a light-emitting material on a surface of a substrate, which can replace costly. Material development 'rapidly and effectively improve the color rendering of flat light sources. The main purpose of the invention is to provide a P-brushing method for a fluorescent material of a flat lamp, which uses a screen printing process technology to print the fluorescent material on the surface of the substrate in stages, which can be arranged by using different patterns of design, or printed differently. A film-thick fluorescent material to achieve a color mixing effect. Another main object of the present invention is to provide a printing method for a fluorescent material of a flat lamp 099127224, Form No. A0101, No. 6/23, 0992047827-0 201209349, which uses a screen printing process technology to print fluorescent materials in stages. On the surface of the substrate, in addition to printing the three primary colors of red, blue and green, a specific spectrum or a specific function of the material can be printed, thereby obtaining light sources of different spectra to improve the color rendering of the light source. [0009] Still another main object of the present invention is to provide a configuration of a fluorescent material for a flat lamp, which can utilize a red fluorescent powder, a green fluorescent powder, a blue luminous powder, and at least A colored lacquer powder is combined into a group of glory materials, and the color mixing effect is achieved by adjusting the pattern arrangement, the area size, the difference in film thickness, and the like, and the light sources of different spectra can be easily obtained.
