Embodiment Construction

[0029] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0030] It should be noted that when a component is referred to as being “fixed on” or “disposed on” another component, it may be directly on the other component or indirectly on the other component. When an element is referred to as being "connected to" another element, it can be directly or indirectly connected to the other element. The orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "top", "bottom" etc. are based on the orientation or positional relationship shown in the drawings, and are only for convenience of de...

Abstract

The invention provides a lamp bar. The lamp bar comprises a printed circuit board, first lamp bead groups and second lamp bead groups, wherein the printed circuit board comprises a board body and a supporting part, and the supporting part protrudes outwards from one side surface of the board body. The first lamp bead groups comprise a plurality of first lamp beads arranged on the board body at intervals, the second lamp bead groups are arranged on the sides of the first lamp bead groups at intervals, the second lamp bead groups comprise a plurality of second lamp beads arranged on the supporting part at intervals, the projections of the second lamp beads on the board body are arranged alternately with the first lamp beads. The invention further provides a backlight module. The invention further provides a display device. According to the lamp bar, the arrangement structure of the double-layer lamp beads is adopted, the projections of the second lamp beads on the board body and the first lamp beads are arranged alternately, under the situation of ensuring the arrangement distances of the lamp beads, more lamp beads are permitted to arrange, so that the technical problem that the number of LED lamp beads arranged on the lamp bar is influenced by the distance between the two adjacent LED lamp beads, and the heat dissipation of the lamp bar is difficult due to the fact that the number of the LED lamp beads is increased is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of display equipment, and more specifically relates to a light bar, a backlight module and a display device. Background technique [0002] With the continuous development of display technology, the replacement of display devices on the market is getting faster and faster, and the resolution requirements of liquid crystal panels are getting higher and higher. However, with the improvement of resolution, the transmittance of liquid crystal panels is getting lower and lower. , resulting in insufficient brightness of the display screen. In order to ensure the brightness of the display screen, the currently commonly used method is to increase the number of LED lamp beads in the backlight module of the display device. A certain distance needs to be kept between each LED lamp bead, so the number of LED lamp beads arranged is limited, and the increase in the number of LED lamp beads will lead to a sharp increase in ...
