Lighting liquid crystal TFT Display Module device

The liquid crystal display is a passive display device, itself does not light, modulated by the external light to achieve TFT Lcd Modules, so that light is a liquid crystal display applications, the key technology. Lighting is generally divided into natural lighting, external lighting settings and projection light source.
Natural lighting
The easy use of natural light, the cheapest, but also not a good way of energy, most of the time, counting, LCD portable instruments are dominated by natural light. Its natural daylighting technologies include:
(1) illumination for optimal viewing. Common perspective of different products in different directions, the direction of the liquid crystal display device optimal viewing angle can be consistent with the commonly used.
(2) try to highlight the Graphic LCD Module window. The LCD window design as much as possible up front can be.
(3) Flexible look outside light. The instrument design into a flat, handheld, easy to use when looking for outside light.
(4) to avoid light interference. For some reflection type liquid crystal display device, in addition to pay attention to find outside light, the need to avoid fluctuations in the surface of the light caused by light interference.
