In order to solve above-mentioned the deficiencies in the prior art, the utility model provides a kind of cover board and touch display screen.
Technical problem to be solved in the utility model is achieved by the following technical programs:
A kind of cover board, including glass substrate, the glass substrate include display area and non-display area, the glass base
Covering ink layer is provided on the non-display area of plate；It is provided on the covering ink layer through the IR for covering ink layer
Hole, is additionally provided with miscella layer of ink on the covering ink layer, and the miscella layer of ink includes sequentially connected IR from bottom to up
Clear ink layer and gloss oil ink layer, the IR clear ink layer cover the non-display area of the glass substrate, and the IR
Clear ink layer is filled up completely in the hole IR, and the IR clear ink layer is completely covered in the gloss oil ink layer；The light
Glue layer and protective film are also pasted on oily ink layer.
Further, the covering ink layer is black ink layer.
Further, the protective film is polyethylene terephthalate protective film.
The utility model also provides a kind of touch display screen comprising above-mentioned cover board, while further including functional sheet, display
Screen, the cover board, functional sheet, display screen are successively bonded.
The utility model has the following beneficial effects:
Different from directly protective film is covered on the hole IR in the prior art, in the utility model, by protective film and
Increase gloss oil ink layer between IR clear ink layer to separate them, gloss oil ink layer plays the work of protection IR clear ink
With guarantee IR clear ink is complete, solves the problems, such as that the hole IR is whitened.
In the utility model, IR clear ink layer and covering ink layer boundary profile having the same, and the profile is located at
Side edge thereof, farther out, while IR clear ink layer is filled up completely in the hole IR for the hole site distance IR, it is therefore prevented that in strong backlight illumination
The generation of boundary halation when lower, to effectively prevent the appearance of halation when cover board IR Kong Qiang backlight illumination.
