Problems solved by technology

[0003] Judging from the current development of displays, the demand for displays today tends to be large in size to meet the needs of consumers. If the arrangement of the U-shaped light tubes in the existing backlight module 10 is only applied to a large-size backlight module, it is usually not possible. To make the display have sufficient brightness, an additional brightness enhancement sheet (not shown) must be added. The brightness enhancement sheet will not only increase the production cost, but also be used in the high-heat backlight module 10, and often cause the brightness enhancement sheet to wrinkle due to high heat factors. As a result of poor display images, how to provide sufficient brightness and better display effects for large-size displays in the limited space of the backlight module is the problem to be solved by the present invention

Embodiment Construction

[0021] see image 3 , Figure 4 , Figure 4A , the backlight module 20 includes a backplane (frame) 21, a lamp tube support seat 24 and a plurality of U-shaped lamp tubes 23, and a lamp tube support seat (not shown) is provided at the lamp tube support seat 24 for supporting U-shaped lamp tube 23, the back plate (frame body) 21 includes a bottom surface 22, and the U-shaped lamp tube 23 has two ends 231, 232 and a curved portion 233, such as Figure 4 As shown, the two ends 231, 232 have electrodes (not shown) that provide power for the U-shaped lamp tube 23, and the two ends 231, 232 and the curved portion 233 define a lamp tube plane S, wherein the lamp tube plane S and The bottom surface 22 forms an inclination angle θ. Please refer to Figure 8 , Figure 8 The opening direction of the U-shaped lamp tube 23 is defined as the right side, so in this embodiment, it can be seen that the opening direction of the U-shaped lamp tube 23 is the same (or called isotropic arrange...

Abstract

The present invention provides a display and its backlight module. The backlight module includes a lamp tube supporting seat, a backplate and at least a 'U'-shaped lamp tube. Said backplate includes an undersurface, and the 'U'-shaped lamp tube is fixed on said backplate, and includes two end portions and a curved portion, said two end portions and said curved portion are limited into a lamp tube plane, and an inclined angle is included between said lamp tube plane and said undersurface. The display includes the above-mentioned backlight module.

Description

technical field [0001] The invention relates to a display and its backlight module, in particular to the arrangement of lamp tubes in the backlight module. Background technique [0002] see figure 1 , figure 2 , Figure 2A , the backlight module 10 of its existing display includes a backplane 11, a bottom surface 12, a U-shaped lamp tube 13 and a lamp tube support seat setting place 14, such as Figure 2A As shown, the lamp tube support base (not shown) is set at the lamp tube support base 14 to support the U-shaped lamp tube 13. It can be clearly seen in the figure that the U-shaped lamp tube 13 in the existing backlight module 10 The arrangement is parallel to the bottom surface 12 and erected on the backboard 11 in a flat manner. [0003] Judging from the current development of displays, the demand for displays today tends to be large in size to meet the needs of consumers. If the arrangement of the U-shaped light tubes in the existing backlight module 10 is only app...
