The schematic diagram of a scenario of colloid is coated on substrate.Please refer to Fig. 3 and Fig. 4, the colloid coating method may include step S31~
S35。
S31：The baffle vertical with substrate is set, and baffle is higher than the upper surface of substrate, and determines area to be coated in ceiling substrate
Domain.
In different types of electronic device, the concrete meaning of the substrate 41 is different, and the application does not limit this
System.For example, in LCD (Liquid Crystal Display, liquid crystal display), the substrate 41 can be PCB
(Printed Circuit Board, printed circuit board), array substrate (Thin Film Transistor Substrate,
TFT substrate or Array substrates) or color membrane substrates (Color Filter Substrate, CF substrates or colorized optical filtering chip base
Plate).In another example in OLED (Organic Light-Emitting Diode, Organic Light Emitting Diode) display, the base
Plate 41 can be the transparent substrates for encapsulating OLED device.
Reserve the region in need for carrying out colloid encapsulation, such as area to be coated shown in Fig. 5 dotted lines in the upper surface of substrate 41
Domain 411.Region 411 to be coated can cover the edge of substrate 41.
The side of baffle 42 is abutted with the side of substrate 41, and baffle 42 and the upper surface of substrate 41 are perpendicular, baffle
42 are higher than the upper surface of substrate 41, and in this, the baffle 42 and the matching of substrate 41 merge one open-topped groove 43 of formation,
The bottom surface of the groove 43 is the upper surface of substrate 41, and the side of the groove 43 is the medial surface of baffle 42.
In other embodiments, if certain sides in region to be coated 411 have been provided with higher than 41 upper surface of substrate
Block piece, then baffle 42 is only arranged at the side that these block pieces are not arranged, as shown in figure 5, baffle 42 is provided only on substrate 41
Left and right side.
S32：Glue is injected in the region to be coated.
The present embodiment can inject glue 44 into groove 43 by nozzle or drip nozzle.Glue 44 is dome in groove 43
The thickness of shape structure, middle section is larger, and the thickness of two side portions is smaller, and the medial surface at the edge and baffle 42 of the glue 44 connects
It touches.
S33：Substrate to injecting the glue shakes.
After injecting glue 44, the application applies shock pulse to substrate 41 in time, so that substrate 41, baffle 42 and glue
44 synchronous vibratings, at this point, using the mobility of glue 44, the glue 44 of middle section is flowed towards marginal portion, and glue 44 exists
The thickness of middle section becomes smaller, and the thickness of edge region increases, finally so that glue 44 is uniform in region 411 to be coated
Distribution, glue 44 become layer structure in homogeneous thickness from dome-like structure.
S34：The glue is cured.
The present embodiment may be used light radiation and cure the glue 44, be carried out to glue 44 for example, by using UV light (ultraviolet light)
Irradiation, so that glue 44 is cured as colloid 45.After hardening, colloid 45 is identical as the shape of glue 44, is still in homogeneous thickness
Layer structure.
S35：Remove the baffle.
It is detached with colloid 45 for ease of baffle 42, in one embodiment, it is low that viscosity may be used in the baffle 42
Material is made, such as the high-molecular organic materials such as polyethylene, polyvinyl chloride are not easy be bonded in this between baffle 42 and colloid 45.
Certainly, the medial surface of the baffle 42 can also be previously provided with film, and the viscosity between the film and colloid 45 is relatively low.
Remove the baffle 42, you can obtain the colloid being formed on substrate 41 45.
It is compared to Fig. 1 and colloid shown in Fig. 2,45 thickness of the colloid is uniform, and edge can cover substrate 41
Edge, and the thickness of colloid 45 be greatly reduced (in practical application scene the thickness of colloid 45 can reduce by 20%~
50%), colloid 45 is thinning, is not easy, by injured, to want the coating of colloid to be conducive to meet flexible display apparatus in bending
It asks.Certainly, the colloid 45 equally can play the role of water proof vapour, etch-proof to bending region.
Fig. 6 is the flow diagram of the colloid coating method of another embodiment of the application.As shown in fig. 6, the colloid applies
Cloth method may include step S61~S67.
S61：The baffle vertical with substrate is set, and baffle is higher than the upper surface of substrate, and determines area to be coated in ceiling substrate
Domain.
S62：Baffle is heated so that baffle keeps predetermined temperature.
S63：Glue is injected in the region to be coated.
S64：Substrate to injecting the glue shakes.
S65：The glue is cured.
S66：Cold wind is blowed to cool down to the baffle.
S67：Remove the baffle.
