Benefits of technology

The present patent provides a display device that has a backlight module and a display module. The backlight module has multiple light emitting units that create a spray angle of up to 135 degrees and below 180 degrees. The display module is placed on top of the backlight module. This design allows for better control of the light spray angle from the backlight module, improving the display quality and efficiency of the display device.

Problems solved by technology

Accordingly, the backlight module may not provide the uniform light to the display module due to the insufficient spacing, and the performance of the display device therefore degrades.

sixth embodiment

[0044]Referring to FIG. 7, FIG. 7 is a schematic diagram illustrating various display devices according to various examples of the present disclosure. For clarity, the supporting structure 106, the controller 110 and the protecting layer 112 of the backlight module 100 are not shown, but not limited thereto. The backlight module 100 may be any one of the backlight modules described in the above embodiments. In the display modules 200 of this embodiment shown in FIG. 7, one of the polarizers 210, 212 is disposed between the first light converting layer 216 and the liquid crystal layer 208. As shown in the part (A) of FIG. 7, the difference between the part (A) of FIG. 7 and the part (A) of FIG. 6 is that the display module 200 in the part (A) of FIG. 7 further includes a third substrate 224, wherein the second substrate 204 is disposed between the first substrate 202 and the third substrate 224, the light converting layer 216 is disposed between the second substrate 204 and the third...

eighth embodiment

[0049]Referring to FIG. 9, FIG. 9 is a schematic diagram illustrating various display devices according to various examples of the present disclosure. For clarity, the supporting structure 106, the controller 110 and the protecting layer 112 of the backlight module 100 are not shown, but not limited thereto. The backlight module 100 may be any one of the backlight modules described in the above embodiments. In the display modules 200 of this embodiment shown in FIG. 9, the display device 10 further includes a transflective layer 226, wherein the light converting layer 216 is disposed between the transflective layer 226 and the light emitting units 102. The transflective layer 226 may be a Bragg layer, or a half transparent metal film. As shown in the part (A) of FIG. 9, one difference between the part (A) of FIG. 9 and the part (A) of FIG. 6 is that the display module 200 in the part (A) of FIG. 9 further includes the transflective layer 226 disposed between the second substrate 204...

Abstract

A display device includes a backlight module and a display module. The backlight module includes a plurality of light emitting units. The display module is disposed on the backlight module, wherein a spray angle of one of the light emitting units is greater than or equal to 135 degrees and less than 180 degrees.

Description

BACKGROUND OF THE DISCLOSURE1. Field of the Disclosure[0001]The present disclosure relates to a display device, and more particularly, to a display device including light emitting units having a wide spray angle.2. Description of the Prior Art[0002]Flat panel display devices, such as liquid crystal display (LCD), inorganic light-emitting diode (LED) display, organic light-emitting diode (OLED) display, and electroluminescent display (ELD), are information viewing technologies for widespread use in a variety of electronic apparatuses, as the characteristics of thinness, lightweight and low dissipation power are widely recognized. As the thickness of the display device continues to be reduced, the distance or spacing for mixing the light emitted from the light-emitting devices in the backlight module is reduced as well. Accordingly, the backlight module may not provide the uniform light to the display module due to the insufficient spacing, and the performance of the display device th...
