A computer-readable medium includes a program code that, when executed by a processing circuitry, causes the processing circuitry to divide a layout of a semiconductor chip into a plurality of patches, generate a plurality of segments from a layout of each of the plurality of patches, wherein a first patch of the plurality of patches includes first segments and a second patch of the plurality of patches includes second segments, calculate hash values respectively corresponding to the first segments and the second segments by using a hash function, calculate bias values of segments having a first hash value from among the first segments, calculate a representative value based on the bias values, and apply the representative value to the segments having the first hash value from among the first segments.

Method for optical proximity correction in which consistency is maintained and method for manufacturing mask using the same

In a light guide plate and a display apparatus having the light guide plate, a light guide plate includes reflective prisms, in which at least one of the reflective prisms includes an inclined angle adjustable according to an inclined surface of a defective portion thereof and compensates for a distortion of light caused by the defective portion.

Light guide plate and display apparatus having the same

A display apparatus includes a light source and a light guide plate including a light incident surface facing the light source and which receive the light, an opposite surface opposite to the light incident surface and which reflects the light and has an arc shape, connection surfaces at opposing sides of the light incident surface and which connect the light incident surface and the opposite surface, an upper surface connected to the light incident surface, the opposite surface and the connection surfaces and which outputs the light, and a lower surface opposite to the upper surface. The light incident surface of the light guide plate includes a first surface extending in a predetermined direction, and second surfaces inclined from the first surface in an area corresponding to the light source such that an optical recess having a polygonal pyramid shape is defined by the second surfaces.

Light guide plate of display apparatus

A backlight assembly includes; a light source including a light emitting surface through which a light exits and an optical member including a first surface disposed adjacent to the light source and a second surface disposed substantially opposite to the first surface, wherein the optical member covers the light source and guides the light therethrough, wherein the optical member includes; an incident surface to which the light is incident, the incident surface being connected with the first surface corresponding to the light source, an optical pattern disposed on the second surface and corresponding to the light source, the optical pattern reflecting a first light of the light incident through the incident surface through total internal reflection and a light guide pattern disposed on the first surface, wherein the light guide pattern directs the reflected first light to an exterior of the optical member.
