摘要： A display device, in particular for a vehicle, has a viewing screen including a liquid crystal cell, the liquid crystal cell having a front cell wall and a rear cell wall and a liquid crystal substance arranged in the cell space between these cell walls, and with a heating device by means of which the display device can be heated. In order to ensure reliable operation of the display device even in the case of low temperatures, the heating device is arranged in the cell space of the liquid crystal cell directly or indirectly on the front cell wall and/or the rear cell wall.

摘要： A display device, in particular for a vehicle, having a screen which has a liquid crystal cell, with the liquid crystal cell having a front and a rear cell wall and a liquid crystal substance arranged in the cell space between these cell walls, and having a heating apparatus by which the display device can be heated. In order to ensure reliable operation of the display device even at low temperatures, the heating apparatus is arranged in the cell space of the liquid crystal cell directly or indirectly on the front and/or, on the rear cell wall, and that the heating apparatus is operated with a pure AC voltage.

摘要： In a display device having a TN liquid crystal cell which can be illuminated by transmitted light from a source of light, the nematic liquid crystal substance of which cell contains a coloring substance. The control regions of the TN liquid crystal cell can be acted on by an actuation voltage between an actuation level and a non-actuation level of the electro-optic characteristic curve, in which connection bright signs can be shown on a dark display surface by the liquid crystal cell. The liquid crystal cell can be acted on by an actuation voltage between the actuation level and a non-actuation level in the undershoot region of the characteristic having the least transmission.

摘要： In a liquid crystal display (1), a laterally arranged light coupling surface (2) permits the active illumination of the liquid crystal display (1) by a light source (3). For this purpose, the liquid crystal display (1) has a light deflecting element (7) which deflects the incident optical radiation in the direction of a liquid crystal cell (5). The light polarized by means of a rear polarization filter (9) is reflected at a rear, reflective element (10) and deflected into the liquid crystal cell (1). The segmented display is therefore produced on a front side (14) of the liquid crystal display (1), provided with a front polarization filter (13). By contrast with known liquid crystal displays having a transflector, it is thereby possible substantially to reduce a possible color deviation and the limited readability associated therewith. At the same time, the cost of production and the overall space required are substantially reduced.
摘要翻译：在液晶显示器（1）中，横向布置的光耦合表面（2）允许通过光源（3）主动照射液晶显示器（1）。为此，液晶显示器（1）具有使入射光辐射沿液晶单元（5）的方向偏转的光偏转元件（7）。通过后偏振滤光器（9）偏振的光在后反射元件（10）反射并偏转到液晶单元（1）中。因此，分段显示器在液晶显示器（1）的前侧（14）上产生，设置有前偏振滤光器（13）。与具有透射反射器的已知液晶显示器相反，由此可以基本上减少可能的颜色偏差和与之有关的可读性。同时，生产成本和总体空间大大减少。
