Description
Technical field:
The present invention is relevant with the filter in the display device, relevant with the filter in the plasma scope (PDP) with anti-electromagnetic radiation and filtering functions, relevant with the filter in the plasma scope (PDP) with contrast enhancement function, relevant with the plasma display system that adopts this filter.
Background technology:
The contrast performance of plasma display 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 patents 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.
