双屏显示装置、双屏显示方法和电子设备
Abstract:
(EN)
A dual screen display device (10), a dual screen display method, and electronic equipment. The dual screen display device (10) comprises: a first display unit (101) and a second display unit (102), a light receiving surface of the first display unit (101) being arranged opposite to a light receiving surface of the second display unit (102); a backlight module unit (107), arranged between the light receiving surface of the first display unit (101) and the light receiving surface of the second display unit (102); a light source unit, used for emitting illumination light to the backlight module unit (107); and a first polarization filtering unit (108) and a second polarization filtering unit (109), arranged on the light receiving surface of the first display unit (101) and the light receiving surface of the second display unit (102) respectively. The polarization direction of the first polarization filtering unit (108) is orthogonal to the polarization direction of the second polarization filtering unit (109). The illumination light is deflected to the first display unit (101) and the second display unit (102) through the backlight module unit (107), and illuminates the first display unit (101) and the second display unit (102) after passing through the first polarization filtering unit (108) and the second polarization filtering unit (109).
(FR)
La présente invention concerne un dispositif (10) d'affichage à double écran, un procédé d'affichage à double écran et un équipement électronique. Le dispositif (10) d'affichage à double écran comprend : une première unité d'affichage (101) et une seconde unité d'affichage (102), une surface réceptrice de lumière de la première unité d'affichage (101) étant agencée face à une surface réceptrice de lumière de la seconde unité d'affichage (102); une unité (107) de module de rétro-éclairage, agencée entre la surface réceptrice de lumière de la première unité d'affichage (101) et la surface réceptrice de lumière de la seconde unité d'affichage (102); une unité de source lumineuse, utilisée pour émettre une lumière d'éclairage vers l'unité (107) de module de rétro-éclairage; et une première unité (108) de filtrage de polarisation et une seconde unité (109) de filtrage de polarisation, agencées respectivement sur la surface réceptrice de lumière de la première unité d'affichage (101) et sur la surface réceptrice de lumière de la seconde unité d'affichage (102). La direction de polarisation de la première unité (108) de filtrage de polarisation est orthogonale à la direction de polarisation de la seconde unité (109) de filtrage de polarisation. La lumière d'éclairage est défléchie vers la première unité d'affichage (101) et la seconde unité d'affichage (102) à travers l'unité (107) du module de rétro-éclairage et éclaire la première unité d'affichage (101) et la seconde unité d'affichage (102) après un passage par la première unité (108) de filtrage de polarisation et la seconde unité (109) de filtrage de polarisation.
