Problems solved by technology

[0004] However, when the optical plate has an irregular structure, if the light-emitting elements are still arranged in a matrix, this will cause irregular shadows at the edge of the optical plate, thereby resulting in uneven brightness across the board

Embodiment Construction

[0018] The relevant protection scope and technical content of the present invention will be clearly presented in the following detailed description of the preferred embodiments with reference to the accompanying drawings. Before proceeding to the detailed description, it should be noted that similar components are designated by the same numerals.

[0019] figure 1 with figure 2 A preferred embodiment of the backlight module of the present invention is shown. Such as figure 1 with figure 2 As shown, the backlight module includes an optical board 2 and a plurality of light emitting diodes 3 . The light emitting diodes 3 are disposed under the optical plate 2 . The backlight module is provided with a panel at its light emitting position, thereby forming a display device.

[0020] refer to figure 1 , the optical plate 2 has an upper side 21, and a lower side 22 spaced apart from the upper side 21, wherein the upper side 21 is an upwardly curved arc, and the lower side 22 ...

Abstract

The invention provides a backlight module. The backlight module comprises an optical plate with at least one arc-shaped edge and a plurality of light-emitting diodes, wherein the plurality of light-emitting diodes are arranged below the optical plate in a plurality of rows; the light-emitting diodes closest to the arc-shaped edge are arranged along the arc-shaped edge in an arc line mode; each rowof light-emitting diodes are arranged along the axial direction; the other adjacent row of light-emitting diodes are arranged at intervals in parallel to the axial direction; and at least one row oflight-emitting diodes and the other adjacent row of light-emitting diodes are arranged in a staggered mode by taking the axial direction as a reference direction. Therefore, the probability of generating shadows on the edge of the optical plate with an irregular shape can be reduced. The invention also provides a display device comprising the backlight module.

Description

technical field [0001] The invention relates to a light source module, in particular to a backlight module and its application on a display device. Background technique [0002] The backlight module can be divided into two types: edge lighting and bottom lighting according to the different incident positions of the light source. Backlight modules are generally used in various information, communication, and consumer products to provide a surface light source for a liquid crystal display (LCD) of the above products. [0003] Conventional optical plates are generally rectangular, and the light source of the direct-light incident light source is a plurality of light emitting elements arranged in a matrix under the optical plate, so that the brightness of each position of the optical plate on the light incident surface is uniform. [0004] However, when the optical plate has an irregular structure, if the light-emitting elements are still arranged in a matrix, this will cause i...
