Abstract
Cover board of the hole IR without halation provided by the utility model, by the setting of IR ink between the anti-lid ink of the second layer and first layer base oil ink, and a trough is set between the bottom edge of IR ink and vision area the top edge, the trough is covered by the anti-lid ink of the second layer, the bottom edge of IR ink is wrapped to form overlap by the anti-lid ink of the second layer, since anti-lid ink is almost lighttight, so the strong light of backlight can not penetrate the edge that anti-lid ink reaches IR ink, avoid the generation of the hole IR halation, improve the operability and visuality of equipment, and IR ink is only one piece of region setting square on the cover board, IR ink usage substantially reduces, cost of material decline, in addition, during IR ink silk screen printing, due to the setting of trough, it can permit fixture flexibly adjustment position It sets, lower for the required precision of fixture, the cost and equipment cost of production technology also reduce accordingly.
Description
Technical field
The utility model relates to cover board fields, more particularly, to a kind of cover board of the hole IR without halation.
Background technique
Touch display screen is component indispensable in modern electronic equipment, generally by cover board, functional sheet and display screen group
At with the diversification of terminal function, in order to the distance between effective awareness apparatus and user's face, present producer
The hole IR, i.e. infrared ray hole are opened up in equipment, the effect in the hole is to make infrared light and shield visible light (380-780nm
Wavelength region) and ultraviolet light (190-380nm wavelength region)；In order to realize above-mentioned effect, the technology being widely used at present is
One layer of IR ink of back side silk-screen in the hole IR, IR ink can filter out the light of 190-780nm wave-length coverage, to only allow red
Outer light penetrates.In the actual production process of cover board, usually outside cover board vision area, one layer of bottom ink of first silk-screen and one layer of anti-lid
Ink, then etching forms the hole IR respectively, finally in IR bore region one layer of IR ink of silk-screen again, thus, bottom ink, anti-lid oil
Ink and IR ink can be near the holes IR there are the region of ink overlapping, and this kind of cover board is when by the strong light direct beam back side, and one
Unconspicuous backside ink halation will be obvious under dim light a bit, and then halation occurs, which is anti-lid ink and IR
Boundary halation between ink.The generation of this halation will affect the beauty of product and the operating experience of user, meeting when serious
User is caused not see the content shown in touch display screen, so as to cause the faulty operation of touch display screen, to bring not
Good consequence.
In response to the above problems, some corrective measures are proposed in the prior art, as CN201820774599.8,
CN201820774596.4, CN201820773357.7 propose cover board of the hole IR without halation, and above-mentioned cover board effectively prevents
The case where hole IR halation, be the generation of halation is prevented by the whole region silk-screen IR ink except cover board vision area, but
It is that in the actual production process, since IR ink needs whole face silk-screen except vision area, the consumption of IR ink is excessive, leads to original
Expect cost increase, and etched again after needing accurate fixture to block in silk-screen printing process or need whole face silk-screen, leads to work
Skill is complicated, and process costs is caused to rise.
Therefore, it is necessary to research and develop a kind of cover board of the hole IR without halation, raw material and production cost are reduced.
Utility model content
The purpose of this utility model is to provide a kind of cover board of the hole IR without halation, are easy to solve the hole prior art IR
Generate halation and the relatively high technical problem of production cost and cost of material of the hole IR without halation cover board.
The utility model provides a kind of cover board of the hole IR without halation, setting first layer base oil ink on the cover board, and described the
The whole region except cover board vision area is arranged in one layer of base oil ink, and the anti-lid ink of the second layer, institute are arranged on first layer base oil ink
State the whole region that the anti-lid ink of the second layer is arranged in except cover board vision area；And in first layer base oil Mo Shangyou first through hole,
There is the second through-hole on the anti-lid ink of the second layer, first through hole, the second through-hole are arranged concentrically to form the hole IR, and the hole IR is located at cover board vision area
Top；
The setting of IR ink is above first layer base oil ink and is located between first layer base oil ink and the anti-lid ink of the second layer, IR
Ink can block whole region corresponding to the hole IR and IR ink is filled up completely in first through hole, and IR ink and second
There are an overlaps around the hole IR between the anti-lid ink of layer；
There is also a trough between the bottom edge and vision area the top edge of IR ink, the trough is by second
The anti-lid ink covering of layer.
Further, the vertical range at the IR ink bottom edge and the hole IR center is that the hole IR center and vision area are most upper
The 1/3-2/3 of method, edge vertical range；This structure design can either guarantee that the anti-lid ink of the second layer has enough spaces to pre-
It stays area cover, and can guarantee effective covering of the IR ink to the hole IR, while the orientation range for blocking fixture is also bigger,
It is lower to the required precision of positioning, be conducive to the control of equipment cost and production cost.
Further, IR ink the top edge and cover board the top coincident.This structure design, in IR oil
When black silk-screen, the top region of IR ink is blocked without fixture, and then production efficiency is higher, process costs are lower.
Further, the shape of the IR ink is round, 2-3 times of a diameter of first through hole diameter, and IR oil
Ink is arranged concentrically with first through hole.The setting of this IR ink shape, which is more advantageous to, effectively blocks the same of the hole IR in guarantee IR ink
Time saves ink, reduces cost of material.
Further, the diameter of second through-hole is 1.0-1.5 times of first through hole diameter.This structure design, energy
It is enough it is easy to produce during block the positioning of fixture, it is more convenient when making the anti-lid ink of the silk-screen second layer.
Further, the first layer base oil ink, the anti-lid ink of the second layer are black ink.Black ink can be to non-
Vision area region is effectively covered, to guarantee that equipment overall appearance is beautiful.
Further, the cover board is plane cover board or curved surface cover board.Plane cover board is at low cost, with wide with range, bent
The vision area of surface cover is wide and can guarantee the streamlined grace of the entirety of equipment.
Above-mentioned cover board of the hole IR without halation, by the setting of IR ink between the anti-lid ink of the second layer and first layer base oil ink,
And a trough is set between the bottom edge of IR ink and vision area the top edge, and the trough is anti-by the second layer
The covering of lid ink, thus, the bottom edge of IR ink is wrapped to form overlap by the anti-lid ink of the second layer, due to anti-lid ink
It is almost lighttight, so the strong light of backlight can not penetrate the edge that anti-lid ink reaches IR ink, so as to avoid IR
The generation of hole halation improves the operability and visuality of equipment, and IR ink is only one piece of square on the cover board region
Setting, IR ink usage substantially reduce, cost of material decline, in addition, during IR ink silk screen printing, due to setting for trough
It sets, can permit fixture flexibly adjustment position, the cost and equipment cost of production technology lower for the required precision of fixture
Also corresponding to reduce.
