Technical field
The relevant a kind of flexible display of the present invention, particularly a kind of with the flexible metal thin plate as the self-luminous of substrate and reflection combined display apparatus and preparation method thereof.
Background technology
Because display development is fallen even can be come the trend development of display frame with on-plane surface towards light, thin, anti-, therefore exploitation becomes present research main flow with flexible base plate as the substrate of display.The substrate of flexible display roughly is divided into two big classes at present, is respectively plastic substrate (plastic substrate) and sheet metal (metal foil).
Though plastic substrate is frivolous, deflection, but the plastic substrate major defect is glass transformation temperature (glasstransition temperature, Tg) low excessively (about 225 ℃), therefore carrying out thin-film transistor (thinfilm transistor, when TFT) making, characteristic for fear of influencing thin-film transistor element is only applicable to low temperature process.In addition, if the plastic substrate thermal coefficient of expansion is too high, and the thermal expansion coefficient difference of the film of itself and thin-film transistor is excessive, causes film breaks (crack) easily.In addition, plastic substrate intercepts the ability of aqueous vapor, oxygen far below sheet metal and glass substrate, needs to make extra barrier layer and can prevent that just element is damaged.
Sheet metal is then too high because of surface roughness, need carry out surface treatment with planarization and also need in addition to make barrier layer with isolated its conduction property, and this barrier layer also has the effect of planarization simultaneously.In addition, sheet metal is that compared to the difference of the maximum of plastic substrate and glass substrate it has opaqueness, therefore only can use the front luminescence technology.The metal current thin plate is applied to emissive type (self-emission) more and shows on the product, as Organic Light Emitting Diode (organic lighting emitting diodes, OLED) display.

Figure 1B is in the C-C ' of Figure 1A generalized section according to the self-luminous of one embodiment of the invention and reflection combined display apparatus.Shown in Figure 1B, in present embodiment, a flexual sheet metal 100 is used as the metal base of display element.The material of this sheet metal 100 is aluminium alloy, pure titanium or titanium alloy.If the surface roughness of sheet metal 100 is too high, then its both side surface (first surface and a second surface) can be carried out a planarization and obtained required flat surfaces.This planarization can be utilized electrochemical polish, and (electrochemical polishing, ECP) polishing of technology or cmp (chemicalmechanical polishing, CMP) reach by technology.One transparent isolation layer 110 is arranged on the first surface and second surface of sheet metal 100.The material of this transparent isolation layer 110 is non-conductive material, as silica (SiO
x), titanium oxide (TiO
x), silicon oxynitride (SiO
XN
y) and silicon nitride (SiN
x).One self-luminous (self-emissive) display layer 200 is arranged on the transparent isolation layer 110 of first surface, and a technology of reflective display 300 as a reflection type liquid crystal display layer, then is arranged on the transparent isolation layer 110 of second surface.
The above-mentioned explanation that continues, spontaneous light display unit 200 can be an organic electric-excitation luminescent and show (organicelectro-luminescene display) unit, Organic Light Emitting Diode (organic lightemitting diodes) display unit or polymer LED (polymer light emittingdiodes) unit.The self luminous display mode of this kind does not need backlight, and light path A is by producing light source in the spontaneous light display unit 200 and then appearing show image.In addition, technology of reflective display 300 is to utilize the light that comes from the outside, and as light path B, after light penetrating reflective display unit 300 and the transparent isolation layer 110, light is produced show image by sheet metal 100 reflections with cremasteric reflex formula display unit 300 light sources.
Fig. 2 A, Fig. 2 B and Fig. 2 C are the partial cutaway schematic of self-luminous according to an embodiment of the invention and reflection combined display apparatus.Shown in Fig. 2 A, spontaneous light display unit 200 comprises: a thin film transistor (TFT) array 21 is arranged on the transparent isolation layer 110 of first surface; A plurality of cathode electrodes 22 are electrically connected at thin film transistor (TFT) array; One luminescent layer 24 is arranged on the cathode electrode 22; A plurality of anode electrodes 26 are formed on the luminescent layer 24; And one protective clear layer 28 be arranged on the anode electrode 26.Wherein, cathode electrode 22 can be indium tin oxide (ITO) electrode or metal electrode.Luminescent layer 24 is an organic electric-excitation luminescent layer.26 of anode electrodes can be indium tin oxide (ITO) electrode.28 of protective clear layers can be mononitride, and it can stop that aqueous vapor enters.This spontaneous light display unit 200 can be arranged in pairs or groups and be utilized low temperature polycrystalline silicon (low temperature polysilicon, LTPS) technology is carried out the making of driving element (as thin-film transistor).Because the use of sheet metal is so the present invention also can utilize the process implementing of amorphous silicon film transistor.In present embodiment, be to be that an organic electric-excitation luminescent layer is an example, so so long as the display layer of positive luminous (top emission) all can be used as luminescent layer, as Organic Light Emitting Diode display layer or macromolecule Organic Light Emitting Diode display layer with luminescent layer.
