Abstract

The present application relates to a light emitting diode packaging module and a display device having the same. Disclosed herein is an LED package module capable of reducing the price by simply reducing the number of LED packages without reducing brightness, and a display device having the LED package module. For this reason, in the LED package module and the display device having the LED package module according to an exemplary embodiment of the present disclosure, a plurality of LED packages are mounted on the LED module substrate in a matrix such that the LED packages are arranged in the longitudinal direction and the lateral direction. Each of the directions is alternately oriented in a cross direction. Therefore, price competitiveness can be improved by simply reducing the number of LED packages without degrading display quality.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2016-0053479 filed with the Korean Intellectual Property Office on April 29, 2016, the entire disclosure of which is incorporated herein by reference. technical field [0003] The present disclosure relates to an LED package module and a display device having the LED package module. Background technique [0004] An LCD device must include a display panel including an array substrate, a color filter substrate, and a liquid crystal layer disposed between the array substrate and the color filter substrate. When an electric field is applied across the display panel, the orientation of liquid crystal molecules in the liquid crystal layer changes, resulting in a difference in light transmittance. [0005] Such a display panel is not self-luminous, and thus requires an additional light source to display the difference in light transmittance as an image. ...
