Abstract
The invention discloses an OLED substrate, which comprises a glass substrate and an OLED device arranged on one side of the glass substrate. The other side of the glass substrate is in the form of a frosted surface. The invention also discloses an OLED display panel. The outer bright-dipping surface of the glass substrate of the OLED substrate glass is uniformly ground, so that the specular reflection of a metallic cathode is eliminated. The foldover phenomenon during the displaying process is solved. Meanwhile, due to the grinding treatment on the outer surface, the total reflection of the OLED display panel during the bright-dipping process is reduced and the brightness of the device is improved. According to the technical scheme of the invention, during the assembling process of the OLED display panel, the good display effect and the higher brightness are realized while no polaroid needs to be pasted. The OLED substrate and the OLED display panel are simple to manufacture and good in economic benefit, thus being suitable for mass production.
Description
Technical field
The present invention relates to display field, particularly relate to a kind of oled substrate and comprise the OLED display panel of this oled substrate.
Background technology
In recent years, OLED owing to showing many superperformances such as grace, light, anti-seismic performance good, operating temperature range is wide, its consumption market and Display Technique flourish.PMOLED(passive type OLED) generally adopt the metal of high reflectance as negative electrode, as aluminium or magnesium silver alloy, ghost image phenomenon is had during display, contrast is improved in order to reduce mirror-reflection, the usual way of industry attaches rotatory polarization sheet at exiting surface, but polaroid transmitance only has about 43%, require higher to display screen intrinsic brightness, therefore can reduce device lifetime; And most client in use can the shell of additional low transmission, therefore requires to improve device brightness, and then affects the life-span.
Summary of the invention
In order to solve above-mentioned the deficiencies in the prior art, the invention provides a kind of oled substrate, the exiting surface of glass substrate is carried out frosted process, polaroid can be pasted and just the mirror-reflection of metallic cathode can be changed into diffuse reflection, eliminate the ghost image phenomenon in display; Total reflection during OLED bright dipping can be reduced simultaneously, improve device brightness and.Present invention also offers a kind of OLED display panel.
Technical problem to be solved by this invention is achieved by the following technical programs:
A kind of oled substrate, comprising: a glass substrate and the OLED be formed on described glass substrate side, the opposite side of described glass substrate is matte surface.
Further, described OLED comprises the anode layer, organic function layer and the cathode layer that are formed in described glass substrate side successively.
Further, described cathode layer is metal cathode layer.
Further, described metal be Aluminum-aluminum alloy, magnesium silver alloy any one.
Further, the mist degree of described matte surface is less than or equal to 40%, is more than or equal to 10%.
Further, described matte surface is formed by the method for mechanical sandblasting or hydrofluoric acid etch.
A kind of OLED display panel, comprise above-mentioned oled substrate corresponding with this oled substrate arrange cover plate, fixed by sealant sealing between described oled substrate and cover plate.
The present invention has following beneficial effect: outer for the glass substrate of oled substrate exiting surface is done even frosted process, eliminate the mirror-reflection of metallic cathode, solve ghost image phenomenon during display, the frosted process of outer surface can reduce total reflection during OLED display panel bright dipping simultaneously, improves device brightness.The present invention need not paste polaroid when OLED display panel assembling uses, and just can reach good display effect and higher brightness; Make simple, be applicable to scale of mass production, there is good economic benefit.
