Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.
The utility model embodiment provides a kind of display panels motherboard, comprises first substrate, second substrate that are oppositely arranged; The substrate peripheral envelope frame glue, the subunit plate that are arranged between described first substrate and described second substrate seal frame glue and primary seal frame glue outward; Be provided with liquid crystal in the zone that described first substrate, described second substrate and described primary seal frame glue enclose; Described substrate peripheral envelope frame glue, subunit plate seal frame glue outward and are provided with opening.
Wherein, substrate peripheral envelope frame glue is coated on the outer peripheral areas of whole first substrate or whole second substrate; The subunit plate seals the periphery that frame glue is coated on subunit plate zone outward, wherein, comprises the substrate regions of a plurality of single display panels in the subunit plate zone; Primary seal frame glue is coated on the periphery of the substrate regions of single display panels.
Among the utility model embodiment, by outside described substrate peripheral envelope frame glue, subunit plate, sealing frame glue opening is set, can guarantee that gas evenly is full of the whole liquid crystal display panel motherboard rapidly, the pressure difference in the outside in the balance primary seal frame glue, significantly alleviate the liquid crystal puncture phenomenon that causes owing to this pressure difference, thereby solve because the gluing relay decline of envelope frame and the liquid crystal pollution problem that the liquid crystal puncture causes.
Preferably, arrange for multiple lines and multiple rows in the subunit plate zone on the display panels motherboard, and on the described substrate peripheral envelope frame glue, the position in corresponding each gap, subunit plate zone is provided with opening on its corner location and each limit; Described subunit plate seals outward on the frame glue, is provided with opening at its corner location.
As shown in Figure 2, be the position view of envelope frame glue on the display panels motherboard.In the utility model embodiment, described first substrate can be array base palte or color membrane substrates, and second substrate can be color membrane substrates or array base palte accordingly, does not limit at this.If described first substrate is color membrane substrates, then described second substrate is array base palte; If described first substrate is array base palte, then described second substrate is color membrane substrates.
As shown in Figure 2, substrate peripheral envelope frame glue 22 is arranged on 21 places, border of close substrate on described first substrate or described second substrate.On the described substrate peripheral envelope frame glue 22, the position in corresponding each gap, subunit plate zone is provided with opening on its corner location and each limit.Described subunit plate seals outer the placing that frame glue 23 is arranged on subunit plate zone outward, and its corner location place also is provided with opening.Primary seal frame glue 24 inside arrange liquid crystal, the opening that described substrate peripheral envelope frame glue 22 and described subunit plate seal outward on the frame glue 23 can guarantee that gas enters the display panels motherboard, make when carrying out first substrate and second substrate to box, the inside and outside side pressure of primary seal frame glue 24 keeps balance by force.
Example, comprise six subunit plate zones on the display panels motherboard among Fig. 2, be 2 row, 3 column distributions, substrate peripheral envelope frame glue 22 is except corner location is provided with opening, still be provided with opening on four limits, opening on each limit is arranged on the position in corresponding each gap, subunit plate zone, the both sides up and down of substrate peripheral envelope frame glue 22 are respectively to there being two gaps between each subunit plate zone, so both sides arrange opening at correspondence position up and down, be respectively arranged with two openings, similarly, the right and left of substrate peripheral envelope frame glue 22 was last to be provided with an opening, and described subunit plate seals 23 need of frame glue outward and at corner location opening is set.
Among the utility model embodiment, by the position in each gap, subunit plate zone of correspondence of four jiaos of described substrate peripheral envelope frame glue and Ge Bian opening is set, and the corner location place that seals frame glue outside described subunit plate also arranges opening, can guarantee that gas evenly is full of the whole liquid crystal display panel motherboard rapidly, the pressure difference in the outside in the balance primary seal frame glue, significantly alleviate the liquid crystal puncture phenomenon that causes owing to this pressure difference, thereby solve because the gluing relay decline of envelope frame and the liquid crystal pollution problem that the liquid crystal puncture causes.
In addition, in display panels, envelope frame glue width is more big, the ability of its anti-liquid crystal puncture is more strong, uses the display panels motherboard that the utility model embodiment provides, and at the ad-hoc location that seals frame glue opening is set, can improve anti-liquid crystal and impact the puncture ability, and do not need wide envelope frame glue, thus can reduce to seal the width of frame glue, and then can realize the narrow frame design of display panels.
Preferably, the zone of the subunit plate on the display panels motherboard is single file or single-row arranging; On the described substrate peripheral envelope frame glue, the position in corresponding each gap, subunit plate zone is provided with opening on its corner location and each limit, also is provided with opening in the centre position on its each limit; Described subunit plate seals outward on the frame glue, is provided with opening at its corner location.
Concrete, for example when the subunit plate zone on the described display panels motherboard during less than 4, will have only a subunit plate zone in every row or the every row, and do not have gap, each subunit plate zone, at this moment, on the described substrate peripheral envelope frame glue, also be provided with opening in the centre position on its each limit.Example, when the subunit plate zone on the described display panels motherboard had 2, as shown in Figure 3, on first substrate or second substrate, the centre position on each limit of substrate peripheral envelope frame glue 22 also was provided with opening.Excessive and the number of the single area in subunit plate on described display panels motherboard zone makes gas more evenly be full of the whole liquid crystal display panel motherboard rapidly very little the time like this.
Preferably, the openings of sizes that seals outward on the frame glue of described substrate peripheral envelope frame glue and subunit plate is 1-10mm.
The envelope frame glue of the display panels motherboard that the utility model embodiment provides just directly is applied as the envelope frame glue that has opening when coating.
" display panels is example; the amount of liquid crystal of each display panels is 2.55mg (theoretical calculating can be full of 100% liquid crystal cell inner volume just); envelope frame glue uses UR-2920, and envelope frame glue design (shown in Fig. 2 or 3) and the existing envelope frame glue design (as shown in Figure 1) of adopting the utility model to provide compare test to adopt 3.97.Test findings shows: the display panels that the envelope frame glue that adopts the utility model embodiment to provide designs near the envelope frame glue neat in edge of liquid crystal side, is subjected to liquid crystal puncture degree very light; And adopt the envelope frame glue of prior art to design, and irregular near the envelope frame glue edge of liquid crystal side, be subjected to liquid crystal puncture degree very heavy.
The above; it only is embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of described claim.
