    • The present invention relates to a display device with a detection system for detecting an input po- sition on a screen (301) of the display. A light guide (302) is arranged adjacent to the screen (301). The light guide (302) has a light source (308) arranged to emit light (310) into the light guide (302). The optical matching between the light guide (302) and its surroundings is adapted such that the light (310) of the light source (308) is normally confined within the light guide (302) by means of total internal reflection. However, a user establishing physi- cal contact with the light guide (302) perturbs the state of total internal reflection, and light (310) will be extracted from the light guide (302). In the display device, light detecting means (303) are arranged to detect said light (310) and relate this detection to an input position where the user contact occurred. The display is preferably an LCD, O-LED or P-LED type display.
    • 本发明涉及具有检测系统的显示装置,用于检测显示器的屏幕(301)上的输入位置。 导光板(302)被布置成与屏幕(301)相邻。 光导(302)具有布置成将光(310)发射到光导(302)中的光源(308)。 光导(302)及其周围之间的光学匹配适于使得光源(308)的光(310)通过全内反射被正常地限制在光导(302)内。 然而,与光导(302)建立物理接触的用户扰乱了全内反射的状态,并且光(310)将从光导(302)中提取。 在显示装置中,光检测装置(303)被布置成检测所述光(310),并将该检测与用户接触发生的输入位置相关联。 显示器最好是LCD,O-LED或P-LED型显示器。

    • A display device for displaying a three dimensional image such that different views are displayed according to the viewing angle. The display device includes a display panel having separately addressable pixels for displaying the image, where the pixels are grouped such that different pixels in a group correspond to different views. The display device further includes a retarder in optical association with the display panel. The retarder includes retarder pixels, where at least one retarder pixel is associated with each corresponding pixel in the display panel. Optical parameters of the retarder pixels are varied as function of the viewing angle associated with the corresponding pixel in the display panel.

    • The electrophoretic display device has a plurality of pixels with an electrophoretic medium (7). Each pixel is divided into a first and a second sub-pixel (1; 2). Each pixel is provided with a common electrode (3) extending over the first and second subpixel. The first sub-pixel is provided with a first sub-pixel electrode (11) and the second sub-pixel is provided with a second sub-pixel electrode (12). Preferably, the first sub-pixel is provided with a first light absorbing layer (21) and the second sub-pixel is provided with a second light absorbing layer (22), while the first and second light absorbing layer are provided at opposite sites of the pixels. Preferably, the electrophoretic medium comprises micro-encapsulated electrophoretic ink. Preferably, the ink comprises two types of particles (31; 32) always staying in the optical path of the pixels. According to the invention a doublesided display device is provided with a single electrophoretic medium.

    • A display device comprising a light guide (12), a front plate (14), and an intermediate electromechanically operable foil (16). Two electrode layers (22, 23) are arranged on either side of the foil (16) to induce electrostatic forces on the foil (16) and to bring selected portions of the foil into contact with the light guide (12), thereby extracting light from the light guide (12). The second electrode layer (22) is arranged on the opposite side of the light guide (12) with reference to the foil (16), and separated from the light guide (12) by means of a refractive layer (28). As no electrode layer is required on the light guide itself, the light path of rays extracted from the light guide is cleaner, and the absorption of light is reduced. The light guide can have a thickness such that the light extracted from the light guide per unit length is sufficient to allow for line-at-a-time addressing.
    • 一种显示装置,包括导光体(12),前板(14)和中间机电操作箔(16)。 两个电极层(22,23)布置在箔(16)的任一侧上以在箔(16)上引起静电力,并使箔的选定部分与光导(12)接触,从而提取光 从光导(12)。 第二电极层(22)相对于箔(16)设置在导光体(12)的相反侧,并且通过折射层(28)与光导(12)分离。 由于在导光体本身不需要电极层,所以从导光体抽出的光线的光路更清洁,并且减少了光的吸收。 光导可以具有这样的厚度,使得从每个单位长度的光导中提取的光足以允许一次一次寻址。
