Embodiment Construction

[0042] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0043] Such as figure 2 As shown, it is a schematic structural diagram of a composite prism sheet provided by an embodiment of the present invention. The composite prism sheet can be used as a part of the backlight module of various display terminals such as TV, computer, mobile phone, ipad, etc., and is arranged above the LED lights in the backlight module. When the LED lamp emits light, it ...

Abstract

The embodiments of the invention provide a composite prismatic lens, a backlight module and a display terminal. The composite prismatic lens comprises a first lens and a second lens. The first lens comprises a first substrate layer and a plurality of first triangle prisms symmetrically arranged on the first substrate layer; the second lens comprises a second substrate layer and a plurality of second triangle prisms symmetrically arranged on the second substrate layer. The first surface is connected with the upper surface of the first substrate layer; the second surface is vertical to the upper surface of the first substrate; the third surface presents a plane or an upwardly protruding arc face. The heights of the plurality of second surfaces are shortened along the central direction of the first substrate layer; the fourth surface is connected with the upper surface of the second substrate layer; the fifth surface is vertical to the upper surface of the second substrate layer; the sixth surface presents a plane or an upwardly protruding arc face. The heights of the plurality of the fifth surfaces are shortened along the central direction of the second substrate layer. Compared with the prior art, the composite prismatic lens of the embodiments has a better brightening effect and can reduce the power loss of the display terminal.

Description

technical field [0001] The embodiments of the present invention relate to the field of optical technology, and in particular to a composite prism sheet, a backlight module and a display terminal. Background technique [0002] With the development of society and technology, more and more people use various display terminals such as TVs, computers, mobile phones, ipads, etc. to surf the Internet and watch videos. High, especially the brightness of the center point. [0003] In the related art, in order to improve the display brightness of its display screen, various display terminals usually adopt figure 1 The prism sheets shown are combined together to form a composite prism sheet. Then the light emitted by the light emitting diode (Light Emitting Diode, referred to as LED) in the backlight module of the display terminal enters from the bottom of the composite prism sheet, and the light is gathered to the center point of the display terminal display screen through the prism...
