Abstract
The present invention relates to an optical sheet and a method of assembling a liquid crystal display module that is capable of preventing an inflow of impurities on a backlight unit, thereby minimizing screen staining caused by the impurities. An optical sheet installed between a liquid crystal display panel and a light guide member according to the present invention includes a transparent peeling sheet adhered to the front surface of the optical sheet facing the liquid crystal display panel; and a semitransparent peeling sheet stuck to the rear surface of the optical sheet facing the light guide member.
Claims8
An optical sheet installed between a liquid crystal display panel and a light guide member, comprising:
- a transparent peeling sheet adhered to the front surface of the optical sheet facing the liquid crystal display panel;
- and
- a semitransparent peeling sheet adhered to the rear surface of the optical sheet facing the light guide member.
A method of assembling a liquid crystal module, comprising steps of:
- providing an optical sheet wherein a transparent peeling sheet and a semitransparent peeling sheet are adhered to the front surface and the rear surface thereof respectively;
- peeling the semitransparent peeling sheet away;
- having the rear surface of the optical sheet, from which the semitransparent peeling sheet is peeled away, face downward and the front surface of the optical sheet, to which the transparent peeling sheet is adhered, face upward;
- and
- irradiating light through a light guide member to the optical sheet to which the transparent peeling sheet is stuck, so as to detect impurities contamination on the light guide member and the optical sheet.
