Abstract:
(EN) Disclosed are an electroluminescent-photoluminescent hybrid display device and a manufacturing method thereof. The electroluminescent-photoluminescent hybrid display device comprises a light guide substrate (10), a light-emitting layer (20) disposed on the light guide substrate (10), and a filter layer (30) disposed on the light-emitting layer (20), wherein the light-emitting layer (20) comprises an electroluminescent layer (21) and photoluminescent layers (22) disposed on both sides of the electroluminescent layer (21), a cathode (213) of the electroluminescent layer (21) is a semi-reflecting and semi-transmitting electrode, and an anode (211) is a transparent electrode. The electroluminescent layer (21) can emit blue light from both the cathode (213) and the anode (211). The blue light emitted from the anode (211) is irradiated onto the photoluminescent layers (22) through directional guidance of the light guide substrate (10), and excites the photoluminescent layers (22) to emit red and green light. The red and green light emitted by the photoluminescent layers (22) is mixed with the blue light emitted by the electroluminescent layer (21) to form white light. The white light is then filtered by the filter layer (30) to achieve a color display. The method of the present invention can increase the light utilization rate and color gamut of a display device.
(FR) La présente invention concerne un dispositif d'affichage hybride électroluminescent-photoluminescent et son procédé de fabrication. Le dispositif d'affichage hybride électroluminescent-photoluminescent comprend un substrat de guidage de lumière (10), une couche électroluminescente (20) disposée sur le substrat de guidage de lumière (10), et une couche de filtre (30) disposée sur la couche électroluminescente (20), la couche électroluminescente (20) comprenant une couche électroluminescente (21) et des couches photoluminescentes (22) disposées sur les deux côtés de la couche électroluminescente (21), une cathode (213) de la couche électroluminescente (21) est une électrode semi-réfléchissante et semi-émettrice, et une anode (211) est une électrode transparente. La couche électroluminescente (21) peut émettre une lumière bleue à la fois de la cathode (213) et de l'anode (211). La lumière bleue émise par l'anode (211) est irradiée sur les couches photoluminescentes (22) par un guidage directionnel du substrat de guidage de lumière (10), et excite les couches photoluminescentes (22) pour émettre une lumière rouge et verte. La lumière rouge et verte émise par les couches photoluminescentes (22) est mélangée à la lumière bleue émise par la couche électroluminescente (21) de façon à former une lumière blanche. La lumière blanche est ensuite filtrée par la couche de filtre (30) pour obtenir un affichage de couleur. Le procédé de la présente invention peut augmenter le taux d'utilisation de la lumière et la gamme de couleurs d'un dispositif d'affichage.
(ZH) 一种电致光致混合发光显示器件及其制作方法,包括:导光基板(10)、设于导光基板(10)上的发光层(20)、设于发光层(20)上的滤光层(30),其中发光层(20)包括电致发光层(21)及设于电致发光层(21)两侧的光致发光层(22),电致发光层(21)的阴极(213)为半反半透电极,阳极(211)为透明电极,电致发光层(21)能够从阴极(213)和阳极(211)两面出射蓝光,从阳极(211)出射的蓝光经过导光基板(10)的定向导光照射到光致发光层(22)上,激发光致发光层(22)发出红光与绿光,光致发光层(22)发出的红光和绿光与电致发光层(21)发出的蓝光混合形成白光,白光再经过滤光层(30)滤光即可实现色彩显示,能够提高光线的利用率,提高显示器件的色域。
