Abstract
A light emitting diode (LED) module and display for hiding physical gaps between modules is provided. An LED module comprises: a board including at least one edge; and an array of LEDs at the board, the array comprising: first LEDs and second LEDs, smaller than the first LEDs, the second LEDs located along the at least one edge of the board, the first and second LEDs all being at a common pitch distance, adjacent sides of adjacent first LEDs separated by a first distance, and the second LEDs being at a second distance from the at least one edge of the board, the second distance smaller than the first distance. The modules may be incorporated into an LED display.
Claims9
A light emitting diode (LED) module comprising:
- a board including at least one edge;
- and
- an array of LEDs on the board, the array of LEDs comprising:
- first LEDs and second LEDs, smaller than the first LEDs,
- the second LEDs located along the at least one edge of the board,
- the first LEDs and the second LEDs all being at a common pitch distance,
- adjacent sides of adjacent first LEDs separated by a first distance, and
- the second LEDs being at a second distance from the at least one edge of the board, the second distance smaller than the first distance.
A light emitting diode display comprising:
- light emitting diode (LED) modules,
- the LED modules each separated by a respective physical gap between the LED modules,
- each of the LED modules comprising first LEDs and second LEDs, the second LEDs located on a respective LED module at the respective physical gap, the second LEDs being smaller than the first LEDs, the first LEDs and the second LEDs all being at a common pitch distance on the respective LED module,
- a size of the respective physical gap selected to one or more of:
- maintain the common pitch distance between the second LEDs of adjacent LED modules when the LED modules are at an operating temperature;
- and
- increase a respective pitch distance between the second LEDs of the adjacent LED modules, relative to the common pitch distance, when the LED modules are in an off-state, such that the respective pitch distance decreases towards the common pitch distance due to heat expansion of the LED modules when the LED modules are in an on-state and at the operating temperature.
