Description
Technical field:
The present invention is relevant with the filter in the display device, relevant with the filter in the plasma display (PDP) with anti-electromagnetic radiation and filtering functions, relevant with the filter in the plasma display (PDP) with contrast enhancement function, relevant with the plasma display system that adopts this filter.
Background technology:
The antireflection of present PDP filter and anti-electromagnetic radiation and filtering functions are to form like this: the outer surface at a sheet glass is pasted the plastic film that is coated with the antireflection rete, pastes the anti-electromagnetic radiation that formed by two layers of plastics and the diaphragm of filtering functions at another side.Wherein one deck is to adopt photoetch method or woven wire wiring method to make the metallic conduction grid on diaphragm to form the anti-electromagnetic radiation function.Have the method that adopts brushing pigment film to form rete or paste on the film of metal wire or wire mesh grid at this layer, form the function of anti-electromagnetic radiation and optical filtering by this two membranes with infrared light optical attenuation plastic film.Because lamination lamination composite methods, various functional membranes are on each tunic sheet, attaching process and combination process require high, be difficult for mechanization and produce continuously, and the cost height, rate of finished products is low, production efficiency is low, and light transmittance is low.
The name of publication number CN1509490A is called the plasma display panel filter and discloses lamination and the various antireflections of lamination (AR) film on transparent substrate, near-infrared (NIR) screened film and electromagnetic interference (EMI) screened film, this functional membrane is the crux film that filter needs, they are that the difference plated film is on plastic basis material or plastic film, need lamination in layer by function again and be stacked on the transparent substrate, transparent substrate is to place being overrided to form of adhesive layer between the resin bed by at least two glassy layers and at least one.
This plated film respectively, the shaping manufacture method of lamination does not still have the essence progress with preceding method again, and still efficient is low, rate of finished products is low, cost is high.Particularly multi-level lamination lamination, the residual volatile matter of the solvent that steam bubble between the lamination and binding agent may exist greatly reduces rate of finished products.
The patent documentation of number of patent application 01804419.0, a kind of display filter is disclosed, this filter is a lamination transparency conducting layer (D) on the one or both sides of macromolecule membrane (B), transparency conducting layer is that combination (Dt)/(DM) with high refractive index transparent thin layer (Dt) and metal film layer (MD) is as repetitive, carry out lamination 2-4 time repeatedly, lamination high refractive index transparent thin layer (Dt) and constituting thereon more also discloses one deck at least in this high refractive index transparent thin layer (Dt) by with indium, more than one of tin and zinc are that the oxide of main component forms.The one deck at least that also discloses in a plurality of metal film layers (DM) is formed by silver or silver alloy.Also disclosing in the close air side of macromolecule membrane (B) also promptly watches face to be shaped on the scheme of individual layer antireflection film layer.Also open and clear conductive layer (D) has the sheet resistance of 0.01-30 Ω/.But this patent is not open and enlightenment is main rete with silver, and on it TiO of lamination one deck high index of refraction
2Rete is at silver layer and TiO
2Between the metal oxide rete of special lamination layer of transparent, utilize this one deck metal oxide self anti-aging capability to stablize the protection that increases silver layer.Utilizing this tunic simultaneously is that the nanoscale film has special absorbability to infrared waves, with common absorption and the blocking capability that improves ultraviolet light, near infrared light, far red light of silver layer and TiO2 rete combination back.Openly do not utilize this layer metal oxide in conjunction with silver layer and the combination of TiO2 rete yet, optimize the visible light transmissivity that whole film is.
In addition, the contrast performance of plasma display also is one of display performance index of paying much attention to of numerous producers and client.Contrast is exactly the ratio of (white) brightness of (black) when the darkest when same point is the brightest on the screen, specifically exactly white signal is subtracted each other in 100% and 0% saturation, again divided by 0% white value (0% white signal is exactly a black), resulting numeral.
Contrast is just from deceiving to white gradual change level.Ratio is big more, and from black just many more to white gradual change level, thereby color representation is abundant more.Contrast is very crucial to the influence of visual effect, and in general contrast is big more, and image is clear more eye-catching, and color is also distinct more gorgeous; And contrast is little, then can allow whole image all dusky.High-contrast all has very great help for definition, details performance, the gray-level performance of image.It is more obvious that details performance, definition and the high-speed moving object of product in some dark portion scenes that contrast is high shows advantage.From definition, two keys that improve contrast are exactly the brightness that improves white brightness and reduce black.
The brightness of plasma display mainly relies on region of discharge discharge excitation fluorescent material luminous.On raising plasma display brightness problem, many patent achievements have been arranged, as 200410038715 patent applications that are called the phosphor of brightness emission green glow of application number, a kind of phosphor of transmitting green light of high brightness has been described, this phosphor demonstrates enhanced brightness under UV excites, it is suitable for plasma display panel.And for example application number is 200610055088, name is called dielectric layer structure and has the patent of the plasma display of described structure, dielectric layer structure with groove is set in plasma display has the described dielectric layer of optimum shape with formation, thus make discharge space the size maximization and strengthened emission brightness and discharging efficiency.
Can accomplish under the very bright situation that in the brightness of display at present the method that improves contrast mainly contains the optimization display drive method.The patent that is called plasma display system and its driving method as 1783183 of publication numbers, relate to a kind of plasma display system and driving method thereof, rising waveform and falling waveform are applied on the scan electrode in the reset cycle of first subdomain of frame by the controller handle, and during the cycle of keeping keeping after voltage is applied on the scan electrode first, when the very first time passes, falling waveform is applied on the scan electrode.Applied first keep voltage after, when second goes by, apply second and keep voltage to keeping electrode.It can reduce power consumption and can improve contrast, so that can show the image of high-contrast.Also just like 1797082 patents that are called liquid crystal display device and driving method thereof of publication number, a kind of display panels is disclosed, corresponding to a plurality of viewing areas of split image.The quantity of the lamp by consider covering the viewing area is set the quantity of split image.Thereby the mean flow rate of entire image and the mean flow rate of split image are compared the brightness that changes each split image according to this comparative result.To the light of each viewing area irradiation corresponding to different brightness.Therefore, dark split image shows secretlyer and shows the score and cut image and show brightlyer in a two field picture, thereby improves contrast.
The method that improves contrast mainly improves the structure of luminous or display element in addition.Be called plasma display and the patent of having used the image display system of this panel as 1889222 of publication numbers, by the laminate component that is made of light absorbing zone and reflection layer is dispersed in each discharge cell, reduce the order of reflection of light-emitting phosphor light beam, and the reflector of visible light is set in the opposite side in the space that takes place with discharge, the brightness reduction is suppressed to Min., in plasma display, improves contrast and brightness.
As can be seen, more than improveing of having of several modification methods at driving method, it is low to do applicability like this, necessarily requires the hardware and software of this display to mate, and has improved cost.The discharge cell structure at display element that has improves, and has undoubtedly also improved cost greatly.
