A display apparatus include a connector, a readable/writable EDID storage to store EDID, and a controller to control the EDID storage to be write-protected from error data transmitted from a computer through the connector. With this configuration, the display apparatus and a method of controlling the same can prevent error data from being stored in an EDID storage.

A method of controlling a display apparatus displaying a picture according to an input video signal including a horizontal synchronous signal and a vertical synchronous signal includes setting one or more exclusive display modes, setting whether to apply an auto-adjustment function to the video signal, determining a display mode of the video signal according to the horizontal and vertical synchronous signals when the auto-adjustment function is set to operate, and performing the auto-adjustment function when the determined display mode is not equal to any one of the one or more exclusive display modes. The display apparatus and the control method thereof selectively perform the auto-adjustment function according to the display mode of the input video signal.

An integrated optical filter apparatus, which can be used for a miniaturized waveguide and can reduce crosstalk between adjacent signals. The integrated optical filter apparatus includes a first optical filter reflecting a light beam of a first wavelength and transmitting a light beam of a second wavelength from an externally incident light beam, and a second optical filter facing the first optical filter and reflecting the light beam of the first wavelength reflected by the first optical filter to the first optical filter. The light beam of the first wavelength is reflected by the first optical filter at least twice to remove noise within the light beam of the first wavelength.

Provided is an optical guide bar including: a light exit portion; light incident portions, on which light is incident, formed on both sides of the light exit portion; and a reflective portion facing the light exit portion and including a prism pattern that reflects light transmitted through the light incident portions towards the light exit portion. A shape of the reflective portion is determined in consideration of an effective light emission width of the light incident portion so that the intensity of light at any portion of the reflective portion is uniform.

A method and a display device for detecting an abnormal video signal by periodically checking R,G,B signals. The method includes selecting an R,G,B signal and setting a region of the selected signals to be checked; detecting a minimum pixel level value in the region of the selected R,G,B signal; comparing the minimum pixel level value for the selected R,G,B signal with a predetermined threshold value and checking if abnormal R,G,B signal are present; and displaying on a screen a message indicating whether the selected R,G,B signal is abnormal.

A polarized light guide plate (LGP), and a method of manufacturing the polarized LGP are provided. The polarized LGP includes: a light source; a first layer that guides light emitted from the light source; a second layer disposed on the first layer and including a first emission unit having repetitive patterns extending in a first direction away from the light source; and a third layer formed of an optically anisotropic material and disposed on the second layer, having an emission surface through which light is emitted, and including a second emission unit disposed on the emission surface and having repetitive patterns arranged in a second direction perpendicular to the first direction.

A light guide panel and a back light unit having the same are provided. The light guide panel includes an isotropic layer and an anisotropic layer. The isotropic layer includes an incident light surface, a transmission surface, and a polarization recycling unit, disposed opposite the transmission surface, which changes a polarization direction of light. The isotropic layer has a first refractive index. The anisotropic layer is formed on the transmission surface and includes a selectively transmitting and reflecting surface opposite the transmission surface, which reflects a first portion of incident light and transmits a second portion of incident light. The anisotropic layer has a first refractive index, identical to the first refractive index of the isotropic layer, with respect to light having a first polarization and has a second refractive index, different from the first refractive index with respect to light having a second polarization.
