Abstract
(EN)
A display device (10), comprising: a backlight module (200), having a backlight area (210) and a light transmission area (220); a display panel (100), being arranged on the backlight module (200); a camera module (20), being arranged under the backlight module (200) and corresponds to the light transmission area (220). The light transmission area (220) of the backlight module (200) is provided with at least one MicroLED light-emitting unit (206). When the MicroLED light-emitting unit (206) of the backlight module (200) is turned on, the camera module (20) does not work and images are displayed normally on a display area (110) and a light-transmitting display area (120) of the display panel (100), thus entering a full-screen display state. When the camera module (20) works, the MicroLED light-emitting unit (206) is turned off, the camera module ( 20) acquires enough imaging rays, and images can be normally displayed on the display panel (100) corresponding to the backlight area (210).

L'invention concerne un dispositif d'affichage (10), comprenant : un module de rétroéclairage (200), ayant une zone de rétroéclairage (210) et une zone de transmission de lumière (220) ; un écran d'affichage (100), étant disposé sur le module de rétroéclairage (200) ; un module de caméra (20), agencé sous le module de rétroéclairage (200) et correspondant à la zone de transmission de lumière (220). La zone de transmission de lumière (220) du module de rétroéclairage (200) est pourvue d'au moins une unité électroluminescente à microdel (206). Lorsque l'unité électroluminescente à microdel (206) du module de rétroéclairage (200) est allumée, le module de caméra (20) ne fonctionne pas et des images sont affichées normalement sur une zone d'affichage (110) et une zone d'affichage transmettant la lumière (120) de l'écran d'affichage (100), entrant ainsi dans un état d'affichage plein écran. Lorsque le module de caméra (20) fonctionne, l'unité électroluminescente à microdel (206) est éteinte, le module de caméra (20) acquiert suffisamment de rayons d'imagerie, et des images peuvent être normalement affichées sur l'écran d'affichage (100) correspondant à la zone de rétroéclairage (210).

一种显示装置(10),包括:背光模块(200),具有背光区(210)以及透光区(220);显示面板(100)设于背光模块(200)上;摄像模块(20)设于背光模块(200)下且对应透光区(220)。背光模块(200)的透光区(220)设置有至少一个MicroLED发光单元(206),当开启背光模块(200)的MicroLED发光单元(206)时,摄像模块(20)不工作,而在显示面板(100)的显示区(110)和透光显示区(120)均能够正常显示画面,从而进入全屏显示状态;当摄像模块(20)工作时,关闭MicroLED发光单元(206),摄像模块(20)获取足够的成像光线,背光区(210)对应的显示面板(100)能够正常显示画面。
