Problems solved by technology
[0004] However, flat-panel displays will continue to become thinner in the future. When the width of the light strip will continue to shrink, the above-mentioned light strip light strip fixing method using drilling holes and screws will no longer be applicable. Cause structural defects or breaks in the light strip, and because the light strip light strip has been drilled, it is necessary to avoid the hole area when laying circuits or wiring, resulting in a reduction in the usable area, so the circuit layout on the light strip is vulnerable to this The limitation of the hole; plus the screw fixing method, the heat flow distribution of the LED strip is easy to concentrate near the screw hole area, which affects its heat dissipation effect

Embodiment Construction
[0023] In order to have a further cognition and understanding of the features, purposes and functions of the present invention, the embodiments of the present invention are described in detail below with reference to the drawings. Throughout the description and drawings, the same component number will be used to designate the same or similar components.
[0024] In the description of various embodiments, when an element is described as being "on / on" or "below / under" another element, it means that it is directly or indirectly on or under the other element. , which may contain other elements set in between; the so-called "directly" means that no other intervening elements are set in between. Descriptions such as "above / up" or "below / under" are described with reference to the drawings but include other possible changes in direction. The so-called "first", "second", and "third" are used to describe different elements, and these elements are not limited by such predicates. For th...

Abstract
The present invention discloses a backlight unit and a display device including the backlight unit. The display device includes a display panel and a backlight unit. The backlight unit includes: a light guide plate; and a light source module adjacent to the light guide plate. The light source The module includes a substrate; a printed circuit board layer, including a metal wiring and arranged on the substrate; a plurality of light sources, having a first height, arranged on the printed circuit board layer, and electrically connected to the metal wiring and at least one protruding component having a second height, disposed on the printed circuit board layer and the metal trace, and the second height is greater than the first height and less than or equal to twice the first height.
Description
technical field [0001] The invention relates to the technical field of displays, in particular to a backlight unit and a display device including the backlight unit. Background technique [0002] Flat panel displays often use light guide plates to guide line light sources into surface light sources, so as to provide a backlight with uniform brightness on the display panel. The above-mentioned line light source can usually be a cold cathode fluorescent lamp (CCFL for short) or a light bar (light bar) in which light emitting diodes (LED for short) are linearly arranged. In recent years, due to the thinning of flat-panel displays, the latter light-emitting diode light strip has gradually become the mainstream of backlight, which is formed by arranging a plurality of light-emitting diodes on a strip-shaped metal substrate. [0003] In the current assembly of the LED strips on the backlight, the above-mentioned elongated metal substrate is often drilled and fixed to a heat sink ...
