LED arrays are often used on the smaller low-information content displays, such as character displays and simple monochrome icon-based TN display types.They’re typically used in the yellow-green color range because this provides the maximum light output at the lowest cost.

The design of edge lit backlights for color applications is similar to mono displays with the edge concept, but they use a separate light guide insert and light box to more efficiently contain and reflect light. Additionally, these systems use a high efficiency reflector and a crossed combination of two brightness enhancement films which act to redirect the light so it is focused more perpendicular to the LCD display and increase the intensity or brightness at the user. It requires two films, one in the X direction and one in the Y direction to focus the entire cone of light.

The advantages of an LED array are the low cost and high uniformity. With the downsides of an LED array backlight system being typically limited to yellow-green spectrum due to LED chip costs and the additional thickness required to house the light array.

The days of the Electroluminescent (EL), Cold Cathode Fluorescent Lamp (CCFL) and front lights, are over for LCD displays. The large TV application was the last to employ a CCFL, but now with the lower cost and improved light quality of LEDs even TV’s have adopted the edge lit LEDs.

The advantages of the edge lit mono style are its thinner design and fewer LEDs, which require less power and can lower costs when dealing with more expensive white, blue, or red multichip LEDs. The edge lit backlight can also be a versatile mechanical component and can incorporate display mounting features directly into the backlight. The LED edge lit (mono) design is the lowest-cost and preferred solution for mono graphic LCD displays.

Unlike LED arrays, edge lit backlight designs align the LED’s to the side(s) of the backlight system. These LEDs fire light along the side into the light-guide instead of directly up like the LED Array. This light travels through the light guide and is evenly distributed light throughout the entire display surface by employing a specially designed and varying texture pattern. This texture on both the front and back surface of the light-guide create small dimples which act to scatter and evenly distribute the light out of the face of the light guide. Larger dimples, or a higher density of dimples, will scatter more light out of the display. The texture pattern will be lighter closest to the LEDs whereas the light intensity is higher and much heavier as you move farther away from the LED. This accomplishes a uniform backlight system where the entire surface is the same luminance independent of the actual distance from the LED light source.

When it comes to LCD displays, one of the most critical components of any design is the LCD backlight system. The backlight enables transflective displays to be visible in low-light situations and enables transmissive displays to be visible, period.

For color display applications, a whole new set of obstacles require a unique backlighting solution. Color filters for color displays block out two-thirds of all light, which means color displays require far brighter backlights to be effective. Additionally the range of color depth requires a much higher luminance to clearly distinguish the color grey shades to result in a vibrant color image to the end user. And when an LCD is competing with outdoor sunlit environments, this luminance requirement is even higher.

LED array backlight designs involve an array of backlight LED chips that are soldered directly to a PCB board and then epoxy encapsulated. The chip form LEDs shine directly toward the LCD display and through a diffuser on the front surface of the backlight to evenly distribute this direct light.
