Problems solved by technology

[0002] At present, all kinds of billboards on the market are mostly occupied by neon lamps and fluorescent lamps. The advantages are traditional craftsmanship, easy production, high brightness, and the disadvantages are power consumption and short life.
Although LED billboards have appeared, the advantages are long life, individualization, and changeable colors, but the disadvantage is that the brightness is not enough

Embodiment Construction

[0019] 1. Select the tube diameter of cold cathode tube, LED tube diameter and quantity according to the required illumination and display brightness.

[0020] 2. Select the thickness of the substrate according to the size of the cold cathode tube and LED, so that the cold cathode tube and LED can be inserted into the periphery of the substrate or tightly attached to the edge of the periphery of the substrate.

[0021] 3. Screen printing or spraying on the surface of the substrate with thin material layers such as photo-induced, electro-induced, photo-sensitive, reflective, and daylighting, or sanding and roughening processes. When the cold-cathode tube and the LED are energized to emit light, the entire surface of the substrate emits light. Become a flat surface light source.

[0022] 4. If the entire surface of the substrate and the personalized characters, numbers, and patterns need to be luminous, the personalized characters, numbers, and patterns should be printed first ...

Abstract

The invention is cold cathode tube which is LBD plate lighting vision technique, its cold cathode tube has small diameter of the cold cathode tube, it has high brightness, low energy-cost, relative high service life, multi-color, and the character that spray and silk-print the light-induce, electric-induce and photosensitive material on the transmit-light board, to change points, stripe lamp-house to surface photo source, that is the lighting display device which can not only used to lighting but also can display, and planar, and can light and display in or out the house.

Description

technical field [0001] It belongs to the application field of optoelectronics and new material technology. Background technique [0002] Various billboards on the market are mostly occupied by neon lamps and fluorescent lamps. The advantages are traditional craftsmanship, easy production, high brightness, and the disadvantages are power consumption and short life. Although LED billboards have appeared, the advantages are long life, individualization, and changeable colors, but the disadvantage is that the brightness is not enough. [0003] Cold-cathode tubes are mostly used for LCD backlight and a small number of lighting. However, cold cathode tubes and LEDs are combined, and various indoor and outdoor billboards made of light-guiding plates and light-guiding plate surfaces are printed with photosensitive, electro-sensitive, and photosensitive materials, which can be used for display and lighting, and can be flattened and Personalization, the advantages are high brightnes...
