    • A light-emitting diode (1) has a first electrode (3), a second electrode (4), a light-emitting layer (5) which comprises a matrix, and ions. A layer (6) of a cation receptor (CR) is positioned adjacent to the first electrode (3), has captured cations, and has generated immobilized cations (+). A layer (7) of an anion receptor (AR) is positioned adjacent to the second electrode (4), has captured anions, and has generated immobilized anions (−). The ion gradients provide for quick response in emission of light (L) when the diode (1) is exposed to a forward bias. A diode (1) is manufactured by first forming a laminate (2) of the above structure. The laminate (2) is exposed to a forward bias to make the ions become immobilized at respective sites (S1, S2) of the respective receptors (CR, AR).
    • 发光二极管(1)具有第一电极(3),第二电极(4),包含基体的发光层(5)和离子。 阳离子受体(CR)的层(6)位于第一电极(3)附近,具有捕获的阳离子,并且已经产生固定的阳离子(+)。 阴离子受体(AR)的层(7)定位成与第二电极(4)相邻,具有捕获的阴离子,并且已经产生固定的阴离子( - )。 当二极管(1)暴露于正向偏压时,离子梯度提供对发光(L)的快速响应。 通过首先形成上述结构的层叠体(2)来制造二极管(1)。 将层压体(2)暴露于正向偏压,使得离子在各受体(CR,AR)的相应位置(S1,S2)处固定。

    • A display device comprises a light emitting picture element (120) and a contrast enhancing element (110). The contrast enhancing element comprises a plurality of wave guides (216) separated by interstitial regions (212) being formed as narrowing recesses. An interface between a wave guide (216) and an interstitial region (212) is provided with a reflective layer. The narrowing recesses form a dead end for incident ambient light which is efficiently absorbed by the contrast enhancing element. On the other hand, light emitted by the picture element (120) of the display device is transmitted through the wave guides (216). As a result, the display device has a relatively high contrast ratio, particularly under bright ambient light conditions.
    • 显示装置包括发光图像元件(120)和对比度增强元件(110)。 对比度增强元件包括由间隙区域(212)分离的多个波导(216),其形成为狭窄的凹部。 波导(216)和间隙区(212)之间的界面设置有反射层。 变窄的凹槽形成入射环境光的死角,该光源被对比度增强元件有效地吸收。 另一方面,由显示装置的像素(120)发射的光通过波导(216)传输。 结果,显示装置具有相对高的对比度,特别是在明亮的环境光条件下。
