A button lighting module is provided including: a light guide plate which has a button through-hole formed in a thickness direction to allow a button device configured to input a command to pass therethrough and has a light refractor provided around the button through-hole to refract a light path upward; and a light source which is configured to radiate light so that the light is incident on the light guide plate through an outer peripheral side surface of the light guide plate.

Button lighting module and button apparatus having the same

Provided is a panel for a display device, a method of manufacturing the same, and a panel assembly including the panel for a display device. The panel for a display device includes a first unit panel and a second unit panel that are consecutively disposed, and a junction configured to bond and connect an edge surface of the first unit panel to an edge surface of the second unit panel facing the edge surface of the first unit panel.

Panel for display device, method of manufacturing the same, and panel assembly

Provided is a method of manufacturing a curved display device, wherein a tape automated bonding (TAB) tape, which includes a base film, a driving chip formed at an upper portion of the base film, a plurality of one-side outer leads formed to bond an output terminal of the driving chip and a terminal of a liquid crystal display (LCD) substrate by an outer lead bonding (OLB) method, and a plurality of the other-side outer leads formed to bond an input terminal of the driving chip and a terminal of a printed circuit board, is designed so that from the end of the OLB bonding part to the part at which the film begins to bend is greater than or equal to the longitudinal length (E) of the driving chip ((4F&#x2212;D/2)&#x2265;E).

Method for fabricating curved display device

The present invention relates to a display apparatus comprising front display unit () and rear display unit (), wherein the front display unit () and the rear display unit () are arranged such that an image on the rear display unit () is visible through a portion of the front display unit (). The front display unit () comprise: a display panel (); a front backlight () which is arranged behind the display panel (), and which includes a first light guide plate () having a projection window () through which an image on the rear display unit () is visible, first light sources () arranged along the circumference of the first light guide plate (), and a reflection sheet () arranged at the rear surface of the first light guide plate () to reflect light and having an image hole () formed at the region thereof that corresponds to the projection window (); a rear backlight () arranged behind the front backlight () and including a second light guide plate () corresponding to the projection window () and second light sources () arranged along the circumference of the second light guide plate (); and a rear optical shutter () arranged behind the second light guide plate (). The rear optical shutter () is made of a transparent material, such that the rear display unit and the front display unit cooperate with one another to display a combined image. The entire screen of the front display unit is capable of displaying an image, without any disconnection of the image, when the rear optical shutter is closed.

Display apparatus

The present invention relates to a display apparatus comprising front display unit (), and rear display unit () arranged behind the front display unit (). The front display unit () comprise: a display panel (); a front backlight () arranged behind the display panel () and including a first light guide plate () having a projection window () through which an image on the rear display unit () is visible, a first light source () arranged along the circumference of the first light guide plate (), and a reflection sheet () arranged at the rear surface of the first light guide plate () to reflect light and having an image hole () formed at the region thereof that corresponds to the projection window (); and a rear backlight () arranged behind the front backlight () and including a second light guide plate () and second light sources (), wherein the second light guide plate () corresponds to the projection window () and is bent into a V-shape, and has a first light guide surface () inclined upwardly as it extends toward the rear thereof, and a second light guide surface () inclined downwardly as it extends from an end of the first light guide surface () toward the rear thereof, and wherein the second light sources () are arranged at an upper end and a lower end of the second light guide plate (), respectively, to illuminate the first light guide surface () and the second light guide surface (), respectively. The rear display unit and the front display unit cooperate with one another to display a combined image. The entire screen of the front display unit is capable of displaying a clear image without any disconnection of the image.
