Description
Technical field
The utility model relates to a kind of color filter layer and barrier layer method that combines that adopts and makes three polar plane displays of anode plate structure.
Background technology
At present, for the field emission flat panel display device that utilizes carbon nano-tube to make as the cathode emission electronic material, the image displaying quality of display is one of important technology index of weighing by planar device.Generally, in the middle of flat panel display device, under the high-tension effect of anode, carry out accelerated motion from the carbon nanotube cathod electrons emitted, send visible light with the phosphor powder layer on higher energy antianode panel bombardment, the visible light transmissive anode plate glass that sends and be transmitted into the device outside.The resolution of display image and contrast are the key technical index of image quality, and the resolution of display device is high more, and shown image is also just fine and smooth, true to nature more, and this can realize by making the higher bus pattern of precision; And contrast is also 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 color representation is also abundant more.High-contrast all has very great help for definition, details performance, the gray-level performance of image.
Aspect contrast adjustment, the carbon nanotube field emission flat-panel display device in adjustment process more is partial to change image brightness, the brightness that promptly increases highlight regions, display white, and also not carrying out relevant treatment for black, this just makes that the contrast adjustment scope is very little.High-contrast needs more black black and brighter white, and the variation of black is vital for the change of high-contrast.Can further increase the black level of display screen by reducing reflection, use the plate glass of low-transmittance can increase the contrast of display image, but also weakened the high brightness of display image simultaneously.To this, in the middle of the carbon nano-tube flat-panel display device, go back the effective solution of neither one.
In addition, guaranteeing also should to simplify the manufacture craft of device under the constant prerequisite of image quality, improving the power that is made into of device, reducing the cost of manufacture of device, this also is the problem that researchers need consideration.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of prior art existence and a kind of manufacture craft that adopts tin indium oxide film, color filter coating and the barrier layer method that combines to make the anode plate structure is provided, and provide adopt this anode plate make, simple in structure, cost of manufacture is cheap, the three-stage structure carbon nanotube cathod field-emission plane display that manufacture craft is simple, manufacturing process is reliable and stable.
The purpose of this utility model is achieved in that and comprises by anode plate, the negative electrode panel, two panels enclose the vacuum chamber that frame constitutes with glass all around, be arranged on control gate electrode structure and insulation insulated column element in the vacuum chamber, the negative electrode panel comprises plate glass, one deck bus is set on plate glass, carbon nano-tube is set on bus, anode plate comprises plate glass, alternating floor silica barrier layer and one deck anode capping layer between being provided with on the plate glass, three filter layers are set at interval: red filter layer on silica barrier layer, blue color filter layer and green filter layer, the anode conducting bar is set respectively on each filter layer, the light-emitting phosphor layer is set on the anode conducting bar.Be provided with on plate glass and supported the insulation insulated column element that the grid row culture is used, the control grid is arranged on the insulation insulated column element.
The utlity model has following good effect:
Prepared silica inoranic membrane barrier layer on backing material plate glass, in order to the infiltration of the constituent intermediate ion that stops glass, the protection filter layer is injury-free, and can the transmission of light not exerted an influence; In the present invention, between inoranic membrane barrier layer and tin indium oxide thin layer, made red filter coating, blue filter coating and green filter film respectively, only can allow the light of this color pass through respectively, for then all absorptions of light of all the other colors.As everyone knows, want to form coloured image, so only need three kinds of primary colors of red, green, blue just passable, trichromatic mutual combination can form colourful color; When needs show black image, if there is not filter coating to exist, allow the light of three kinds of colors not pass through so, also the black that just forms.But not all light all has been blocked, and still has part light to be reflected out, and is only not too obvious.From the angle of display image, just demonstrate general black.After in the middle of device, having applied filter coating, red filter coating only can allow red light see through, and green filter film only can allow green filter film see through, and blue filter coating only can allow blue filter coating see through, so when showing black image, Red Green Blue does not pass through, meanwhile, because the existence of filter coating, can not there be all the other light to be launched out, like this, from the angle of display image, can demonstrate the darker black of color.So, we adopt this method can obtain darker black, and the brightness with increase voltage increases highlight bar promptly obtains brighter white, has just increased the contrast of display image, makes white whiter, and black is more black.Make image clear more eye-catching, color is also distinct more gorgeous, and color representation is also abundanter.High-contrast all has very great help for definition, details performance, the gray-level performance of image.In the utility model, increased anode capping layer.The making of anode capping layer, its main purpose are the interference that reduces the parasitic electrons emission, further increase the quality of display image.Therefore have simple in structure, cost of manufacture is cheap, the advantage that manufacturing process is reliable and stable.
