Title
(EN) REINFORCEMENT FRAME, COMPONENT UNIT, AND DISPLAY
(FR) CADRE DE RENFORT, UNITÉ CONSTITUTIVE ET DISPOSITIF D'AFFICHAGE
(JA) 補強フレーム、部品ユニット、および表示装置
Abstract
(EN)
Disclosed is a reinforcement frame (38) fixed to an outer package (37) of a heated component unit in a display (69), wherein a first heat dissipation fin is included in the reinforcement frame (38).  With such an arrangement, even when heat generated when a component unit (such as a backlight unit in a liquid crystal display) is driven, e.g. driving heat of various elements included in the component unit, is transmitted to the outer package (37) of the component unit, the driving heat is further transmitted to the reinforcement frame (38) which is in contact with the outer package (37) and dissipated by means of the first heat dissipation fin.  Consequently, the various elements in the component unit are not impaired by driving heat.
(FR)
L'invention porte sur un cadre de renfort (38) fixé à un boîtier externe (37) d'une unité constitutive chauffée dans un dispositif d'affichage (69), une première ailette de dissipation de chaleur étant comprise dans le cadre de renfort (38). Avec une telle configuration, même lorsque la chaleur générée quand une unité constitutive (telle qu'une unité de rétroéclairage dans un dispositif d'affichage à cristaux liquides) est entraînée, par exemple de la chaleur générée par différents éléments compris dans l'unité constitutive, est transmise au boîtier externe (37) de l'unité constitutive, ainsi qu’au cadre de renfort (38) qui est en contact avec le boîtier externe (37), et la chaleur est dissipée à l'aide de la première ailette de dissipation de chaleur. Par conséquent, les différents éléments dans l'unité constitutive ne sont pas détériorés par la chaleur générée.
(JA)
 表示装置(69)にて熱を帯びる部品ユニットの外装(37)に取り付けられる補強フレーム(38)において、補強フレーム(38)の内部には、第1放熱フィンが含まれる。このように構成することで、部品ユニット(液晶表示装置におけるバックライトユニット等)が駆動することで生じる熱、例えば、部品ユニットに含まれる種々素子の駆動熱がその部品ユニットの外装(37)に伝わったとしても、その外装(37)に接触する補強フレーム(38)に駆動熱は伝わり、さらに第1放熱フィンによって、その駆動熱は放熱される。そのため、部品ユニットにおける種々素子等は駆動熱によって劣化しない。
