Problems solved by technology

However, when used in LED displays, the transparent encapsulants and transparent reflective cups in traditional LED packages may reflect too much background light
When viewing a display that includes a traditional LED package, it can be difficult for the user to see what is displayed if the display reflects too much background light
For example, users may find it difficult to read displayed text in the sun if the display reflects most of the sunlight

Abstract

The invention provides an LED device with an LED package comprising an LED and an optical element in an optical receiving relationship with the LED. The optical element has a higher light absorbing property at an exit surface away from the LED than at a bottom surface proximal to the LED. The optical element may include different epoxies, dye, and opaque particles. A display including the LED device and a method for producing the LED device are also provided.

Description

technical field [0001] The present disclosure relates generally to light emitting diodes (LEDs), and more particularly, to an LED device with reduced reflection and an LED display including the LED device. Background technique [0002] In recent years, LED technology has greatly improved, leading to the introduction of LEDs with enhanced brightness and color fidelity. Thanks to these improved LEDs and improved image processing techniques, large-format, full-color LED video screens have become available, and they are now widely used. LED displays typically comprise a combination of individual LED panels that provide an image resolution determined by the distance between adjacent pixels, or "pixel pitch." [0003] Outdoor displays intended for viewing from greater distances have larger pixel pitches and typically include discrete arrays of LEDs. In a discrete LED array, clusters of individually mounted red, green and blue LEDs are driven to form pixels that present full colo...
