A display device includes: pixels each connected to a corresponding scan signal among scan lines, a corresponding data line among data lines, and a corresponding emission control line among emission control lines; and an emission driver which supplies an emission control signal to the emission control lines. The emission control signal includes a first emission control signal having a first width and a second emission control signal having a second width during an active area of one frame.

Display device and method of driving the same

An optical film is provided. The optical film includes a base film and a cover film. The base film includes a base member and a plurality of lens patterns disposed on the base member. The plurality of lens patterns protrudes from the base member and extends in a first direction. The cover film is disposed on the base film to cover the base member and the plurality of lens patterns. A refractive index of at least one of the lens patterns is smaller than a refractive index of the cover film. An aspect ratio of the at least one of the lens patterns ranges from 0.8 to 1.6.

Optical film and a liquid crystal display including the same

A display device includes a display panel, an optical film arranged on an upper portion of the display panel and including first and second intaglio pattern portions having different depths from each other, a bonding member configured to contact at least a part of the display panel and a surface of the first intaglio pattern portion and an air layer configured to fill between a surface of the second intaglio pattern portion and the display panel.

Display device and optical film included therein

A backlight unit including an optical pattern sheet and a liquid crystal display are provided. The backlight unit includes a light guide plate, a light source portion arranged adjacent to a side surface of the light guide plate to emit light, a mold frame having an extension portion that covers an upper portion of the light source portion and a part of an upper portion of the light guide plate, and an optical pattern sheet arranged on a lower portion of the extension portion to shade or diffuse incident light, wherein the optical pattern sheet includes a base film and an optical pattern portion positioned on the base film.

Optical pattern sheet, backlight unit, and liquid crystal display having the same

A backlight unit which provides light to a liquid crystal display panel of a liquid crystal display. The backlight unit includes an optical lens module including an optical lens disposed above a point light source and configured to refract light output from the point light source, and a reflective polarization layer disposed directly on the optical lens and configured to separate polarization components of the light to transmit one polarization component and reflect another polarization component.

Optical lens module and backlight unit

A light source package includes a first light source configured to emit first light, an imaginary central axis of the first light extending in a first direction. The light source package may further include a second light source configured to emit second light, an imaginary central axis of the second light extending in a second direction that is different from the first direction. The light source package may further include a first optical part including a first surface that is configured to reflect at least a first portion of the first light. The light source package may further include a second optical part configured to spread the second light. The light source package may advantageously enable illuminating a desirably large display area with a minimum number of light sources and/or optical parts.
