Problems solved by technology

[0004] However, when displaying a 3D image, the light emitted by a part of the 3D light-emitting module does not directly pass through the image display panel, but first shoots to the 2D light-emitting module, and after being reflected by the 2D light-emitting module, enters the user's eyes, resulting in Unexpected bright and dark staggered moire (Moire) and crosstalk with the image on the display panel, reducing the display quality of the autostereoscopic image display device

Embodiment Construction

[0054]The invention provides a backlight module with two light-emitting modules and a display device using the backlight module, which can improve the image crosstalk problem caused by light reflection between the two light-emitting modules, and achieve the effect of improving the quality of the display device. In order to make the above-mentioned embodiments and other objects, features and advantages of the present invention more comprehensible, several preferred embodiments are specifically cited below and described in detail with accompanying drawings.

[0055] However, it must be noted that these specific implementation cases and methods are not intended to limit the present invention. The invention can still be implemented with other features, elements, methods and parameters. The proposal of the preferred embodiment is only used to illustrate the technical characteristics of the present invention, and is not used to limit the patent scope of the present invention. Those...

Abstract

A back light module includes a first light emitting module, a second light emitting module and a light attenuator. The first light emitting module has a light-exiting surface, and the second light emitting module is disposed on one side of the first light emitting module opposite to the light-exiting surface. The light attenuator disposed between the first light emitting module and the second light emitting module and includes a first polarizer having a first absorption axis.

Description

technical field [0001] The present invention relates to a display device and its back light module, and in particular to a switchable 2D / 3D image display device and its back light module. Background technique [0002] Generally speaking, three dimensional displays can be divided into stereoscopic type and autostereoscopic type. Among them, the naked-eye display is equipped with special optical elements inside, such as a parallax barrier or a lenticular lens, so that the left and right eyes of the user can respectively observe the image with parallax on the display device, forming a sense of perception. Stereoscopic image. In order to meet the needs of users to watch two-dimensional (2D) images at the same time, a switchable 2D / 3D display device is proposed, allowing users to switch between two display modes of 3D images and 2D images. [0003] A typical switchable 2D / 3D display device includes a 3D light emitting module and a 2D light emitting module. When displaying a 3D...
