Provided are an electronic apparatus for determining validity of touch key input and a method and apparatus for determining validity of touch key input for the electronic apparatus. The method includes determining whether a touch key is input to perform a preset function, determining whether a dummy key used to determine validity of input of the touch key is input, if determining that the touch key is input, and determining validity of input of the touch key based on whether the dummy key is input. According to the present invention, by determining whether touch key input is intended by a user, it is possible to prevent a function undesired by the user from being performed.

A backlight assembly includes a lamp unit, a covering member, a panel guiding member and a lamp supporting member. The lamp unit has a first electrode and a second electrode disposed at a first side of the lamp unit and a curved portion disposed at a second side of the lamp unit that is opposite to the first side. The covering member covers at least one of a first region corresponding to the first and second electrodes and a second region corresponding to the curved portion. The panel guiding member is configured to support a display panel that displays images using light generated by the lamp unit. The lamp supporting member is configured to retain the lamp unit. Therefore, a number of inverters may be reduced, thereby lowering cost and time of manufacturing the backlight assembly. Furthermore, reliability of the backlight assembly may be enhanced.

The light diffusion member includes a light diffusing body and a light diffusing layer. The light diffusing body includes a polymer mixture obtained by uniformly blending a first polymer having a first glass transition temperature and a second polymer having a second transition temperature higher than the first transition temperature. Alternatively, the light diffusing body includes a copolymer prepared from the first and the second polymer. The light diffusing body diffuses an incident light through a light exiting surface. The light diffusing layer is formed on the light exiting surface of the light diffusing body and includes a binder resin having beads. A back light assembly including the light diffusion member and a liquid crystal display device including the light diffusion member exhibit an improved luminance and an improved light diffusing efficiency.

To prevent particles from infiltrating into a display apparatus, a liquid crystal display panel supporting member includes a first particle interceptor and a second interceptor. The first particle interceptor is formed along the top face of the first supporting member frame portion facing a bottom plate of a liquid crystal display panel that is to be mounted on the liquid crystal display panel supporting member. The first particle interceptor has at least two cut portions. The second particle interceptor is disposed between the cut portions to prevent particles from infiltrating into the first particle interceptor. Thus, the liquid crystal display apparatus may prevent deterioration of its display quality.

The present invention is broadly directed towards a receiving container for an LCD apparatus for securing a lamp and lamp wiring connected to a lamp. The receiving container has features for substantially preventing the lamp wiring from being disconnected from the lamp. For example, a first through-hole for receiving the lamp wiring, a first trench, securing members, and securing projections are utilized to substantially prevent lamp wiring from being disconnected from a lamp. Additionally, the LCD apparatus is easily handled, dissipates heat effectively, and has a light weight.

Liquid crystal display and assembly thereof

Disclosed are a back light assembly for preventing discoloration and deformation caused by heat generated from a lamp, and a liquid crystal display device for displaying an enhanced image. The back light assembly includes a receiving container, a lamp, a glass substrate and a diffuser. The receiving container has a receiving space. The lamp for generating the light is disposed in the receiving space. The glass substrate is interposed between the liquid crystal display panel and the lamp. The diffuser diffuses the light generated by the lamp so as to unify a luminance distribution of the liquid crystal display panel. The liquid crystal display device includes the back light assembly.
