What is considered acceptable brightness and spatial uniformity depends upon the particular application for which the backlight will be used. Examples of polarization control layers include a quarter wave retarding layer and a polarization rotating layer such as a liquid crystal polarization rotating layer. Although depicted as having one or more light sources positioned along one side of the backlightlight sources can be positioned along two, three, four, or more sides of the backlight A schematic representation of a portion of this type of backlight is illustrated in FIG. LCD panels, because of their method of operation, utilize only one polarization state of light, and hence for LCD applications it is important to know the backlight's brightness and uniformity for light of the correct or useable polarization state, rather than simply the brightness and uniformity of light that may be unpolarized. The geometry can be tailored to achieve high efficiency and brightness and color uniformity in the backlight. The high intensity point sources cause uniformity problems with conventional direct-lit backlights as well as edge-lit systems that utilize solid light guides. These indices represent the refractive index of the subject material for light polarized along mutually orthogonal x- y- and z-axes, respectively see FIG. Referring again to FIG.

    Optical bonding technology is to inject optical glue into the space between a touch screen(or a cover glass) and the LCD panel to remove the air gap.

    Therefore, the relative amount of s-pol vs. As seen in FIG. If the number of layers in a single packet generated directly in a feedblock do not provide sufficient reflectivity, then two or more such films can be attached to increase the reflectivity. The presence of such a gap, especially when used in conjunction with the front reflectors described herein, can help hide the partition by reducing the local luminance nonuniformity that can be caused by the presence of the partition.

    With a film such as this in the LCD panel with a horizontal pass axis, more light would exit the cavity to either side than at normal incidence, i.

    In general, the use of a high index biaxially birefringent material, such as the one illustrated in FIG.

    The APF front reflector increases the brightness to the normal angle cone by a factor 1. Thus, different zones of the output area can be controlled to be brighter or darker than other zones, or the zones can emit in different colors, simply by appropriate control of the different light sources in the different recycling cavities. Stretch ratios of approximately to 1 may be preferred, although ratios as small as 1 to 1 and as large as 6 to 1 may also be appropriate for a given film. Typically rated level 3H pearlthey can be treated to achieve level 7H quartz.

    For example, for a rectangularly shaped backlight, one or more light sources can be positioned along each of the four sides of the backlight.

    Example applications include in-vehicle displays and digital signage, defibrillators, marine displays and in-flight entertainment systems.

    The first and second diffuserscan be the same or different diffusers. P-pol light is light that is polarized in the plane of incidence of the light ray and a given surface, where the plane of incidence is a plane containing both the local surface normal vector and the light ray propagation direction or vector.

    Such a configuration provides an increase in the optical gain of the display system in two dimensions.

    Light in the first angular distribution remains substantially trapped within the cavity until it is eventually absorbed, thereby diminishing the efficiency of the backlight.

    Additionally, thermal sensors can be used to monitor and control the output of LEDs.

    The backlight includes a front reflector and a back reflector that form a hollow light recycling cavity The partitions can be made of or covered with a highly reflecting material such as the ones listed as suitable for the back reflector; alternatively, one or more partitions can also be partially transmissive.

    Example applications include in-vehicle displays and digital signage, defibrillators, marine displays and in-flight entertainment systems.

    1. Winmate offer different approach to enhance the display to have better viewability near sunlight.

    2. The dark rectangle represents the actual position of a pencil sitting in a bowl of water. The backlight can also include one or more side reflectors located along at least a portion of the outer boundary of the backlight that are preferably lined or otherwise provided with high reflectivity vertical walls to reduce light loss and improve recycling efficiency.
