Title (EN) DIRECT-TYPE BACKLIGHT DISPLAY MODULE AND DISPLAY DEVICE
(FR) MODULE D'AFFICHAGE DE RÉTROÉCLAIRAGE DE TYPE DIRECT ET DISPOSITIF D'AFFICHAGE
(ZH) 直下式背光显示模组及显示设备
Abstract:
(EN) A direct-type backlight display module and a display device. The direct-type backlight display module comprises: a backlight module (100) and a liquid crystal display panel (300) which correspond to each other, and a main control circuit (400) connected with the backlight module (100) and the liquid crystal display panel. The backlight module (100) comprises a back plate (110), a light emitting structure provided on the back plate (110), a diffusion board (140) directly facing the light emitting structure, and an electromagnetic input module (200) provided between the light emitting structure and the liquid crystal display panel (300); the electromagnetic input module (200) comprises an electromagnetic diaphragm (210) provided between the light emitting structure and the liquid crystal display panel (300), and an electromagnetic control circuit electrically connected with the electromagnetic diaphragm (210), the light transmittance of the electromagnetic diaphragm (210) being greater than or equal to 50%; the electromagnetic diaphragm (210) is connected with the main control circuit (400) by means of the electromagnetic control circuit. According to the technical solution, electromagnetic touch input is integrally fused into the direct-type backlight display module, and moreover, it can be ensured that a liquid crystal display screen has a good display effect.
(FR) Un module d'affichage de rétro-éclairage de type direct et un dispositif d'affichage. Le module d'affichage de rétroéclairage de type direct comprend : un module de rétroéclairage (100) et un panneau d'affichage à cristaux liquides (300) qui correspondent l'un à l'autre, et un circuit de commande principal (400) connecté au module de rétroéclairage (100) et au panneau d'affichage à cristaux liquides. Le module de rétroéclairage (100) comprend une plaque arrière (110), une structure électroluminescente disposée sur la plaque arrière (110), une carte de diffusion (140) faisant face directement à la structure électroluminescente, et un module d'entrée électromagnétique (200) disposé entre la structure électroluminescente et le panneau d'affichage à cristaux liquides (300); le module d'entrée électromagnétique (200) comprend un diaphragme électromagnétique (210) disposée entre la structure électroluminescente et le panneau d'affichage à cristaux liquides (300), et un circuit de commande électromagnétique connecté électriquement au diaphragme électromagnétique (210), la transmittance de lumière du diaphragme électromagnétique (210) étant supérieur ou égal à 50 %; le diaphragme électromagnétique (210) est connecté au circuit de commande principal (400) au moyen du circuit de commande électromagnétique. Selon la solution technique, une entrée tactile électromagnétique est intégralement fusionnée dans le module d'affichage de rétroéclairage de type direct, et en outre, il peut être garanti qu'un écran d'affichage à cristaux liquides a un bon effet d'affichage.
(ZH) 一种直下式背光显示模组及显示设备。该一种直下式背光显示模组,包括相互对应的背光模组(100)和液晶面板(300),以及与背光模组(100)和液晶面板连接的主控电路(400);背光模组(100)包括背板(110),设置于背板(110)上的发光结构,与发光结构正对的扩散板(140),以及设置于发光结构与液晶面板(300)之间的电磁输入模组(200);电磁输入模组(200)包括设置于发光结构与液晶面板(300)之间的电磁膜片(210),以及与电磁膜片(210)电连接的电磁控制电路,电磁膜片(210)的透光率大于或等于50%,电磁膜片(210)通过电磁控制电路与主控电路(400)连接。本技术方案,可将电磁触控输入一体化地融合到直下式背光显示模组中,还能保证液晶屏具有良好的显示效果。
