Abstract
In the method, abnormal liquid crystal raw material is ground to 'ultramicro-nanostate' main material according to actual requirement by utilizing special manufacturing machine, artificial liquid crystal display screen can be manufactured according to normal liquid crystal screen manufacturing process by adding proper amount of photosensitive material, increased transmission layer is added on screen surface in camera lens manufacturing process and low voltage analog digital signal or digital signal is displayed on screen for finalizing electric singal to image signal conversion through two connector bases set on screen.
Description
Technical field
This invention is that the non-common liquid crystals raw material of a kind of usefulness shields manufacturing process with common liquid crystals, produces the manufacture method of no high voltage radiation, ultra-thin, fine and smooth, numeric type, colored imitative LCDs.The display screen of this method manufacturing can be used for computer display screen or television screen etc.
Background technology
Most of originally televisors and computer display screen be to adopt electron gun emission high pressure (about about 9～16 kilovolts) electron beam, deflection according to certain rules, and the impact fluorescence screen scans the screen epigraph, finishes electricity～light conversion.(the about 10 microns fluorescent powder of deposition one layer thickness on the kinescope panel interior surfaces of glass and this video screen is worked under high pressure conditions; the outside is the layer of aluminum film; the impact of (above be added with high pressure) blocks ions works to attract electron beam and protection fluorescent powder).This video screen volume is big, and the radiance height that high voltage causes has similar " stroboscopic " of snowflake down, to health, the particularly fine stimulation that has in various degree of eye.And LCDs pattern originally is gloomy dominant hue because of picture effect, and background color and pattern colour are close, and image color is beautiful inadequately abundant.
Summary of the invention
The purpose of this invention is: the deficiency that the high voltage width of cloth is penetrated in order to overcome, stroboscopic, color are abundant inadequately provides a kind of " imitative liquid crystal " colorful display screen.
The technical scheme of this invention is: (1) is with a kind of material that is different from original general liquid crystal raw material, with special being machined to " ultra micro " or near " nanometer " shape; To reduce the unit volume of pixel, increase the full frame absolute number value that holds pixel.Add indispensable photosensitive material again, regulate fluoroscopic color motif and brightness.Reach and make the fine and smooth and coloury purpose of image.(2) according to the video picture principle of LCD screen: " with very little voltage signal; by two binding post input electrical signals (simulating signal or digital signal) of drawing from screen is displayable image, finish electricity～light (being electric signal～picture signal conversion) conversion.Usually only 1.5 volts get final product." remove the high voltage picture tube system of electron gun formula, replace with " imitative liquid crystal " display screen; And two signals of installation transmit binding posts on this screen.No longer including the high voltage radiation thus exists.(3) if this display screen is used as television screen, as long as increase a simulation～digital quantizer, just can clear, stable digital picture be presented on " imitative liquid crystal " display screen, solved the stroboscopic problem.(4) in order to overcome ubiquitous owing to exist the light reflex to stimulate the deficiency of sense organ, the manufacture technology additional " anti-reflection film " on this screen top layer according to camera lens, and make that anti-reflection film thickness is the u/4f of sodium yellow wavelength.(5) if this screen is used for the video wall of outdoor jumbotron, can in common enclosure shell commonly used, increase one deck zeyssatite (SiO2) raw material liner, be made into thickening constant temperature protective seam according to the sector technology, solve of the influence of four seasons temperature Change to screen.
Beneficial effect
The principle of this invention and characteristics: " imitative liquid crystal " display screen that this manufacture method is made has replaced numerous and diverse, the dangerous electron gun picture tube high voltage screen of technology.Useful health safety, harmless assurance are provided for manufacturing, use, the maintenance of display screen.And excessively having drawn a shortcut, when having saved fund, also brought the enjoyment of unexpected environmental protection science and technology for China application of electronic technology field " mould revolution " for users.
Imitative liquid crystal raw material described in this invention is: the former raw material (three primary colors proportioning toning routinely) that is used for making " light emitting diode " is main, be equipped with terres rares luminescent material (concrete proportion scale can suitably be adjusted at specification size and practical use), get final product according to synthetic making of the technology of the conventional LCD screen of prior art.
In the manufacturing process of anti-reflection film, can calculate the thickness of anti-reflection film according to this formula: u represents the light velocity value of this monochromatic light in medium in the minimum thickness of anti-reflection film=u/4f formula, and f represents this monochromatic frequency values.The principle of this technology is: according to the light interference phenomena principle, coat thin film (generally using magnesium fluoride) on the screen top layer.When the thickness of film be incident light the film medium wavelength 1/4 the time, the light that on two faces of film, reflects, path length difference equals half wavelength just, thereby cancels each other.This has just significantly reduced reflected light.

Embodiment
This invention can be used as computer display screen or television screen and all use the series of products of color/graphics.Now carrying out home theater and the manufacturing of the used ultra-large type screen of outdoor TV wall experiment.Success on one day is enjoyed endless for human!
