Abstract: The present invention relates to a virtual ray tracing method and dynamic light field refocusing display system, ray information collection, or random retrieval for pixels on a full focus image, so as to reduce ray collection total; and/or simplifying cross point retrieval where an object surface is regarded smooth. The system includes a virtual reality content processor, a virtual reality monitor, an eyeball tracker, an eyeball tracing processor, and a ray refocusing processor. The present invention reduces computational complexity, enables automatic replacement of erroneous sampling, causes to achieve real and accurate refocusing. The present invention may enable dynamic refocusing along a gazing direction of the human eye, and enable focusing by a user to objects of variable distance, to be consistent with viewing characteristics of the human eye.

Abstract: A direct-bonding liquid crystal display module, comprising a liquid crystal panel protection layer (1), a liquid crystal panel (2), and a backlight module (3). The liquid crystal panel protection layer (1) is bonded to the front side of the liquid crystal panel (2). The backlight module (3) is mounted on the back side of the liquid crystal panel (2). A housing support (5) is provided at the side surface of the backlight module (3) at an interval. The front side of the housing support (5) is provided with a positioning groove (51). The liquid crystal panel protection layer (1) is embedded in the positioning groove (51) and is fixedly connected thereto. The housing support (5) is fastened and connected to the back side (34) of the backlight module (3) by means of a fastener (6).

Abstract: An interactive high-clarity glass electronic whiteboard having a writing board body; the writing board body includes a base board and an ultra-thin tempered glass. The front of the base board attaches with the ultra-thin tempered glass. The attaching surface of the ultra-thin tempered glass attaching the base board is adhered with a non-transparent interlayer. A non-transparent coating is adhered to an attaching surface of the ultra-thin tempered glass attaching the base board A writing surface of the ultra-thin tempered glass is a matte surface with anti-glare treatment.

Abstract: A hard-screen polarizing plate for a liquid crystal screen includes a polyvinyl alcohol film (1) and a protective film (2). The protective film (2) is adhered to a surface of the polyvinyl alcohol film (1) facing a light emitting surface (41) of a liquid crystal cell (4). The hard-screen polarizing plate further includes a glass substrate (3). The glass substrate (3) is adhered to a light emitting surface (12) of the polyvinyl alcohol film (1) for serving as a protective layer of the second light emitting surface (12) of the polyvinyl alcohol film (1). The hard-screen polarizing plate is adhered to a light emitting surface (41) of the liquid crystal cell (4).
