Abstract: A backlight module for a liquid crystal display includes: LEDs; LED drivers; a controller that outputs data and the latch signal to the LED drivers; data lines for transmitting the data; and latch signal lines for transmitting the latch signal. The latch signal lines are wired according to each of a plurality of first groups obtained by dividing LED drivers. The data lines are wired according to each of a plurality of second groups, which are constructed with a collection of at least one LED driver selected from each of the plurality of first groups without duplication, and each data line is commonly connected to at least one LED belonging to the corresponding second group.

Abstract: A display device includes a liquid crystal display (LCD) panel, a rear frame, a light guide plate, and a light emitting diode (LED) substrate. The LED substrate includes a first substrate portion, a second substrate portion, a plurality of LEDs mounted to the first substrate portion, and a power connector mounted to the second substrate portion. The first substrate portion extends in a first direction along a first side of the light guide plate that faces the first sidewall of the rear frame. The second substrate portion extends in a second direction along a second side of the light guide plate that faces the second sidewall of the rear frame. A backlight unit for a display device includes a light guide plate and a LED substrate.

Abstract: A liquid crystal display device is provided. The liquid crystal display device includes: a liquid crystal cell including a liquid crystal layer interposed between a pair of transparent substrates; a backlight unit behind the liquid crystal cell; a polarizer on a surface of the liquid crystal cell, the surface opposing the backlight unit; a transparent reinforcement plate that is between the liquid crystal cell and the backlight unit and supports the polarizer; and an intermediate frame, which is a middle frame, including a protrusion protruding toward a space between the backlight unit and the transparent reinforcement plate. The transparent reinforcement plate rests on the protrusion of the intermediate frame.
