Abstract:
(EN) Provided are: a display device which is capable of efficiently dissipating heat generated at a light source substrate by means of a simple structure; and the like. According to the present invention, a display device is provided with: a panel module that has a front surface on which an image is displayed; a light guide plate which is arranged so as to face the back surface of the panel module; a light source substrate that has one surface on which a light emitting element that supplies light to the panel module is mounted, said light source substrate being arranged such that the one surface faces the peripheral edge of the light guide plate; a heat dissipation plate which is thermally connected to the light source substrate; and a case that constitutes the framework. The heat dissipation plate is thermally connected to a back plate of the case.
(FR) L'invention concerne : un dispositif d'affichage qui est capable de dissiper efficacement la chaleur générée au niveau d'un substrat de source de lumière au moyen d'une structure simple; et similaire. Selon la présente invention, un dispositif d'affichage comporte : un module de panneau qui a une surface avant sur laquelle une image est affichée; une plaque de guidage de lumière qui est agencée de façon à faire face à la surface arrière du module de panneau; un substrat de source de lumière qui a une surface sur laquelle un élément électroluminescent qui fournit de la lumière au module de panneau est monté, ledit substrat de source de lumière étant agencé de telle sorte que la première surface fait face au bord périphérique de la plaque de guidage de lumière; une plaque de dissipation de chaleur qui est reliée thermiquement au substrat de source de lumière; et un boîtier qui constitue le cadre. La plaque de dissipation de chaleur est thermiquement reliée à une plaque arrière du boîtier.
(JA) 光源基板で発生した熱を、簡易な構造で効率的に放熱することができる表示装置等を提供する。表示装置は、正面に画像を表示するパネルモジュールと、前記パネルモジュールの背面に対向して配置された導光板と、前記パネルモジュールに光を供給する発光素子を一面に実装し、該一面を前記導光板の周縁に対向して配置された光源基板と、前記光源基板と熱的に接続された放熱板と、外郭を構成する筐体とを備え、前記放熱板は、前記筐体の背面板に、熱的に接続してある。
