Light emitting module and display apparatus
The present disclosure provides a light emitting module and a display apparatus. Alight emitting module according to an embodiment includes a bar-shaped circuit board; a plurality of light emitting devices disposed on the circuit board; and a reflection wall surrounding the light emitting devices, in which the plurality of light emitting devices is divided into at least two strings, and each of the strings includes light emitting devices connected in series.
1 . A display apparatus, comprising:
a display panel; and
a backlight source providing light to the display panel,
wherein the backlight source includes first and second light emitting modules disposed near one side surface of the display panel,
each of the first and second light emitting modules, comprising:
a circuit board;
a plurality of light emitting devices disposed on the circuit board; and
a reflector disposed on the circuit board,
wherein the plurality of light emitting devices forms one or more strings,
wherein light emitting devices in one string are connected in series,
wherein a maximum forward voltage difference between the first light emitting module and the second light emitting module is 1.5V or less, and
wherein a thickness of a first portion of the reflector disposed between two adjacent grooves in a string is greater than that of a second portion of the reflector disposed at an edge of the string.
2 . The display apparatus of claim 1 ,
wherein the one or more strings are connected to each other in parallel.
3 . The display apparatus of claim 2 ,
wherein a maximum forward voltage difference between two of the one or more strings in the first and second light emitting modules is 1.5V or less.
4 . The display apparatus of claim 1 ,
wherein the reflector include reflection walls, and one of the reflection walls surrounding light emitting devices in one string is spaced apart from another one of the reflection walls surrounding light emitting devices in another string.
5 . The display apparatus of claim 4 ,
wherein each of the reflection walls includes a plurality of grooves, and at least two light emitting devices are disposed in each of the plurality of grooves.
6 . The display apparatus of claim 4 ,
wherein a height of one of the reflection walls is greater than a height of the plurality of light emitting devices.
7 . The display apparatus of claim 1 ,
wherein a distance between the second portion of the reflector and a first light emitting device in a groove closest to the second portion of the reflector is smaller than a distance between the first portion of the reflector and a second light emitting device in the groove.
