Technical field
The present invention relates to a kind of flexible display apparatus that comprises flexible base, board, this flexible base, board accommodates a plurality of electrooptical switching elements.The invention still further relates to a kind of method of making this flexible display apparatus.
Background technology
The at present emerging market of flexible display apparatus.Typically, make bent thin substrate made of plastic provide mechanical flexibility for this display unit always.In document US 2004124763, disclosed the example of flexible display apparatus.A plurality of pixels that this flexible display apparatus comprises flexible base, board and be arranged to the row and column form on substrate surface.In order to improve the flexibility of display, a plurality of parallel grooves are provided in substrate surface, wherein each channel shaped is formed between adjacent two row or two row display pixels.Except providing flexible, groove also is used to reduce the propagation of the mechanical stress that causes when bending or rolled display device.
But, the shortcoming of the flexible display apparatus that discloses among the US2004124763 is that because the layout and the attribute of groove, it is flexible only on a dimension.Other known flexible display apparatus also show similar shortcoming.For example, for using two flexible plastic substrates and therebetween as for the flexible display apparatus of pixel or electrooptical switching element, may buckle (buckling) when simultaneously along two dimension bending displays the time, this may cause the local defect in the display again.In other words, on meaning more generally, these display unit are that can curl rather than flexible.
Summary of the invention
The objective of the invention is to overcome this problem, and the flexible display apparatus of improvement is provided, it can once be bent along surpassing a direction.
These and other purposes that will understand from following description are by realizing according to the flexible display apparatus of claims and the method for this flexible display apparatus of manufacturing.
According to an aspect of the present invention, a kind of flexible display apparatus is provided, it comprises: flexible base, board, and be contained in a plurality of electrooptical switching elements on the described substrate, wherein said substrate has a plurality of break-through openings of the repeat patterns be arranged to, and makes described electrooptical switching element be arranged in the substrate regions adjacent with described opening.Preferably, described opening is arranged to lattice, promptly is arranged to the network of evenly spaced horizontal line and vertical line.
The break-through opening allows to bend display unit along both direction simultaneously, has the tensile stress or the compression that reduce in base plan.
Preferably, at least one opening has the basic extension that equates along two vertical direction in the plane of described substrate, forms two main extensions.In addition, described at least one opening has than the described main little extension of extending along the direction between described two vertical direction.Described opening for example can form as cross.
Preferably, opening is evenly distributed, that is, all openings are orientated along equidirectional.In addition, each opening is set so preferably, makes two main extension align with lattice.For example, the described first main direction of extending can be parallel to the horizontal line of lattice, and the described second main extension can be parallel to the vertical line of lattice.This has realized the display unit increased flexibility.
Opening can define a plurality of first areas and a plurality of second area of substrate, and each first area can hold the part of at least one electrooptical switching element or electrooptical switching element, and second area does not have the electrooptical switching element and connects adjacent first area.Here, bending action focuses on second join domain.So the moment of rupture of display unit will mainly cause moment of rupture along join domain rather than by the first switch element zone.Join domain is long more, more flexible display device.In addition, can be used to be electrically connected the lead of electrooptical switching element by the second area guiding.
Can further stiffener be attached to each first area, wherein the size of stiffener corresponds essentially to the size of first area.For example stiffener can be placed on the opposite side of substrate, make not any light of interrupt switch element emission of plate with respect to the electrooptical switching element.Even stiffener makes that electrooptical switching element self is not the flexible very soft display unit that yet can provide.The bending action of substrate focuses on the join domain that connects each first area that holds the electrooptical switching element.

In addition, flexible display apparatus can comprise, especially can comprise the flexible diffusion element as active display or (LED) during light source, and this diffuse component is used to receive and the light of diffusion from the electrooptical switching element.For example, inorganic LED is a spot light, and a plurality of LED that are distributed on the substrate surface will can not allow whole base plate luminous, and it is luminous only to allow to be coated with the fraction of substrate of light source.Adopt diffuser, can obtain more uniform decoupling light from substrate surface.When the electrooptical switching element by the long region separation that flexibly connects when opening, diffuser is especially favourable.Diffuser also is favourable when using inorganic LED, and wherein each LED is surrounded by conducting region, to distribute the heat that LED sends out.
Preferably, diffuse component comprises one deck fabric at least, and more preferably, diffuse component comprises one deck non-textile fabric at least.Non-textile fabric is to be made by fleece, by the machinery winding of fiber, or utilizes resin, thermal welding and formation chemical complex to make the fleece combination.Fiber in the net can be arranged to random fashion or oriented approach.So non-textile fabric comes down to the mixture of air and fiber at random.Therefore, it contains two kinds of essential elements and is used for diffusion: air, and the randomness of fiber material.And it is very soft, and this makes it be particularly suited for having the luminous display unit of the flexibility of enhancing.
The density of non-textile fabric on can be than diffuse component in the face of the density on the one side of electrooptical switching element opposite with the electrooptical switching element one side of diffuse component is low.For example, diffuse component can comprise with the ground floor non-textile fabric of the adjacent setting of electrooptical switching element and be arranged on second layer non-textile fabric on the ground floor that the density of the wherein said second layer is higher than the density of ground floor.
Diffuse component has low-density near the part of electrooptical switching element, so more provide the gap between the tight section at electrooptical switching element and diffuse component.In this gap, may spread apart before running into the more tight section of diffuse component from the light cone of electrooptical switching element or its emission, in the tight section most light diffusion is taking place more.Even when display unit is bent etc., the low-density part also help to make the electrooptical switching element and more the space between the tight section keep acceptable steady state value.The more tight section of diffuse component is used for diffused light and therefore provides homogeneity to the surface of containing light.
As substituting of non-textile fabric diffuse component, diffuse component for example can comprise foam, textile fabric or any other suitable material.
Display unit can also comprise the elastomer layer that is arranged between substrate and the diffuse component, is used to improve the homogeneity of display unit.
Display unit can also comprise outermost layer, and this outermost layer comprises one deck whitish fabric at least.The whitish fabric coating for example can be placed on the diffuse component.Fabric can be for example weave or the braiding, to bring the sensation of fabrics in general to device.Preferably, coating for white or turn white to avoid colour filter.
Outermost layer can also comprise at least one cover layer of colored open structure fabric on the whitish fabric coating.Perhaps, outermost layer only comprises this at least one cover layer of colored open structure fabric.Cover layer of colored open structure fabric for example can be fishnet or mesh fabric type fabric.The contrast that cover layer of colored open structure fabric is being served as on the display unit improves antireflecting coating, and it allows display to have random color in off position down, and (because hatch frame) do not serve as colour filter under opening.
Flexible display apparatus can also comprise the drive electronics that is used to drive the electrooptical switching element, and wherein drive electronics is separated with flexible base, board.So drive electronics is not on flexible base, board.Compare with the display that drive electronics is positioned on the flexible base, board, this can improve the flexibility of display base plate, because bigger drive electronics parts can't be injury-freely by the big angle of bending.Preferably, drive electronics is positioned on the rigid substrates that separates with flexible base, board.
