Technical field

The invention relates to display, and particularly relevant for display panels.

Background technology

Traditional display panels is to be made up of colored optical filtering substrates (Color Filter Substrate), active component array base board (Activc Component Array Substrate) and the liquid crystal layer (Liquid Crystal Laycr) that is disposed between this two substrates.More proposed now (Color Filtcr on Array on the directly whole active component array base board of colored filter; C OA) or with black matrix" (Black Matrix; BM) be made on the thin-film transistor array base-plate (Black Matrix on Array, technology BOA) is with COA substrate or BOA substrate and the assembling of another subtend substrate; And between two substrates, insert liquid crystal molecule, to form display panels (cell).

Usually,, need on COA substrate or BOA substrate, to form first mark, correspondingly, need on the subtend substrate, form and COA substrate or the corresponding mark of BOA substrate in the technology of carrying out COA substrate or BOA substrate or when carrying out the assembling of display panels.

In view of this, how designing a kind of display panels, so that form corresponding mark with the corresponding subtend substrate of active component array base board, so that the assembling of display panels, is the technical matters that needs to be resolved hurrily of person skilled in the industry.

Summary of the invention

In order to solve the problems of the technologies described above, the present invention proposes a kind of display panels, comprise: an active component array base board has a colored filter and at least one first mark; One subtend substrate is configured in the top of said active component array base board, and said contraposition substrate sees through laser-induced thermal etching to form at least one second mark, and said second mark is corresponding with said first mark; And a liquid crystal layer, be configured between said active component array base board and the said subtend substrate.

In one embodiment of the present invention, said subtend substrate comprises a glass substrate, wherein, sees through the said glass substrate of laser-induced thermal etching to form said second mark.

In one embodiment of the present invention, said subtend substrate also comprises transparent conductive film, is configured in a surface of said glass substrate, wherein, sees through the said nesa coating of laser-induced thermal etching to form said second mark.

In one embodiment of the present invention, said transparent conductive film is indium tin oxide films or indium zinc oxide film.

In one embodiment of the present invention, dispose at least one first separation material between said active component array base board and said subtend substrate.

In one embodiment of the present invention, also dispose at least one second separation material between said active component array base board and said subtend substrate.

By on can know, display panels proposed by the invention, see through laser to the subtend substrate carry out etching with form with active component array base board on the corresponding coordinate of the elements of a fix, by this, can be convenient to the assembling of display panels.

Description of drawings

Embodiment

Understand technical scheme of the present invention better in order to make this area person skilled; The accompanying drawing that will combine embodiment of the present invention below; Technical scheme in the embodiment of the present invention is carried out clear, intactly description; Obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiments.

Please with reference to Fig. 1, Fig. 1 has illustrated the diagrammatic cross-section of the display panels of an embodiment of the present invention.

As shown in Figure 1, display panels 1 comprises an active component array base board 11, a subtend substrate 12 and a liquid crystal layer 13.

Active component array base board 11 comprises at least one first mark 111, and this first mark 111 is a location mark.Active component array base board 11 also comprises glass substrate 112, colored filter 113 and transparent conductive film 114, and wherein first mark 111 is configured on the glass substrate 112 with colored filter 113, and transparent conductive film 114 is configured on the colored filter 113.In this embodiment,, can think that then active component array base board 11 is the COA substrate because of colored filter 113 is configured on the active component array base board 11.

Subtend substrate 12; Be configured in the top of active component array base board 11, and contraposition substrate 12 sees through laser-induced thermal etching, can form at least one second mark 121; Wherein, This second mark 121 is corresponding with first mark 111, and more particularly, second mark 121 and first mark 111 satisfy one-one relationship.In this embodiment; Subtend substrate 12 comprises a glass substrate, and promptly it only is a glass substrate, and this moment; Formation for second mark 121; Can directly adopt this glass substrate of laser-induced thermal etching with first mark, 111 relative bit positions and reach, particularly, then be to burn welding glass to form second mark 121 through laser.

Liquid crystal layer 13 is configured between active component array base board 11 and the subtend substrate 12.Liquid crystal layer 13 the insides have a plurality of liquid crystal molecules.

As shown in Figure 1, display panels 1 also comprises at least one first separation material 14 and at least one second separation material 15, is configured between active component array base board 11 and the subtend substrate 12.In this embodiment; First separation material 14 can be light separation material (Photo Sapccr); It can be used for confirming the spacing between active component array base board 11 and the subtend substrate 12, and second separation material 15 can be first separation material 14 constitute with the black matrix" (BM) that is configured on the active component array base board 11, and the material of first separation material 14 and black matrix" is identical; In other words; Second separation material 15 is equivalent to the combination of first separation material 14 and black matrix", and promptly second separation material 15 had both had first separation material, 14 roles, also had the black matrix" role that is configured on the active cell array matrix 11; The active component array base board 11 of this moment can be thought the BOA substrate

In this embodiment, see through laser subtend substrate 12 is carried out etching, forming second mark 121, and this second mark 121 is corresponding one to one with first mark 111 on the active component array base board 11, by this, can make display panels 1 be convenient to assemble.

Again please with reference to Fig. 2, Fig. 2 has illustrated the diagrammatic cross-section of the display panels of another embodiment of the present invention below.

Display panels 1 ' shown in Figure 2 is the different of subtend substrate with the difference of display panels 1 shown in Figure 1; Other is then identical; Like active component array base board 11, liquid crystal layer 13, first separation material 14 and second separation material 15 is same structure; Concise and to the point in order to narrate, repeat no more at this.

As shown in Figure 2, subtend substrate 12 ' comprises glass substrate 122 and transparent conductive film 123, and wherein, transparent conductive film 123 is configured in the surface of leaning on active component array base board 11 these one sides of glass substrate 122.In this embodiment, can with first mark, 111 relative bit positions, see through laser transparent conductive film 123 carried out etching; After the etching; Make transparent conductive film 123 be divided into transparent

conductive film

123a, 123b, and formed mark 124, and mark 124 is corresponding with mark 111.

Preferably, at this embodiment, transparent conductive film 123 is tin indium oxide (Indium Tin Oxide, ITO) film or indium zinc oxide (Indium Zinc Oxidc, an IZO) film, but not as limit.

In the preceding text, illustrate and describe embodiment of the present invention.But those skilled in the art can understand, and under situation without departing from the spirit and scope of the present invention, can also specific embodiments of the invention do various changes and replacement.These changes and replacement all drop within protection scope of the present invention.
