The application requirements for your display will determine the brightness of the backlight. Is the display being used in high ambient lighting, or outdoor environments for example? Anders can help enhance the brightness of your display in several ways:
LED chips 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 direct light.
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.
In contrast to LED arrays, the edge lit LEDs are formed around the rim of the screen, using a special diffusion panel to spread the light evenly behind the screen. This accomplishes a uniform backlight system where the entire surface is the same luminance independent of the actual distance from the LED light source.
