QUANTUM DOT LIGHT-EMITTING DEVICE AND BACKLIGHT MODULE
(FR)
DISPOSITIF ÉLECTROLUMINESCENT À POINTS QUANTIQUES ET MODULE DE RÉTROÉCLAIRAGE
(ZH)
一种量子点发光器件及背光模组
Abstract:
(EN)
Provided are a quantum dot light-emitting device (12) and a backlight module. The backlight module comprises a backplane (11) and a diffusion plate (9) which are sequentially stacked. One surface of the backplane (11) facing the diffusion plate (9) is provided with multiple quantum dot light-emitting devices (12). The quantum dot light-emitting device (12) comprises an LED light-emitting chip (10), a support structure (1) and a lens integration structure (18). The lens integration structure (18) comprises a lens body (2), a quantum dot layer (3) and a first water and oxygen barrier layer (4). The lens body (2) has a recess. The quantum dot layer (3) and the first water and oxygen barrier layer (4) are sequentially arranged at the recess in a direction from a bottom end to an opening of the recess. The first water and oxygen barrier layer (4) covers the opening of the recess of the lens body (2). The lens integration structure (18) is adhered and fixed to the support structure (1). The invention can significantly reduce a failure rate of quantum dot excitation and manufacturing costs.
(FR)
L'invention concerne un dispositif électroluminescent à points quantiques (12) et un module de rétroéclairage. Le module de rétroéclairage comprend un fond de panier (11) et une plaque de diffusion (9) qui sont empilés de manière séquentielle. Une surface du fond de panier (11) faisant face à la plaque de diffusion (9) est pourvue de multiples dispositifs électroluminescents à points quantiques (12). Le dispositif électroluminescent à points quantiques (12) comprend une puce électroluminescente à DEL (10), une structure de support (1) et une structure d'intégration de lentille (18). La structure d'intégration de lentille (18) comprend un corps de lentille (2), une couche de points quantiques (3) et une première couche barrière à l'eau et à l'oxygène (4). Le corps de lentille (2) présente un évidement. La couche de points quantiques (3) et la première couche barrière à l'eau et à l'oxygène (4) sont disposées de manière séquentielle au niveau de l'évidement dans une direction allant d'une extrémité inférieure à une ouverture de l'évidement. La première couche barrière à l'eau et à l'oxygène (4) recouvre l'ouverture de l'évidement du corps de lentille (2). La structure d'intégration de lentille (18) est collée et fixée à la structure de support (1). L'invention peut réduire de manière significative un taux de défaillance d'excitation de points quantiques et les coûts de fabrication.
(ZH)
一种量子点发光器件(12)及背光模组,背光模组包括依次层叠的背板(11)和扩散板(9),背板(11)朝向扩散板(9)的表面设有多个量子点发光器件(12)。量子点发光器件(12)包括LED发光芯片(10)、支架结构(1)和透镜集成结构(18),透镜集成结构(18)包括透镜本体(2)、量子点层(3)和第一水氧阻隔层(4),其中,透镜本体(2)设有凹部,凹部由底端向开口的方向依次设有量子点层(3)和第一水氧阻隔层(4),第一水氧阻隔层(4)覆盖于透镜本体(2)的凹部开口处,透镜集成结构(18)与的支架结构(1)胶粘固定,极大程度的降低了量子点激发的失效率和制造成本。
