A display apparatus including a frame, a cover, a display panel, a light source and a reflective layer is provided. The cover is connected to the frame to form an accommodating space. The display panel is disposed in the accommodating space. The light source is disposed on the frame and adjacent to the cover. The reflective layer is disposed on a first surface of the cover facing the frame, and is located between the light source and the cover. The reflective layer extends between the light source and the display panel, and does not overlap a display area of the display apparatus.

Display apparatus

The backlight module includes multiple backlight units. Each backlight unit includes a first light emitting unit and multiple second light emitting units. The first light emitting unit has a first beam angle, and each second light emitting unit has a second beam angle which is narrower than the first beam angle. In a first mode, a light intensity of the first light emitting unit is equal to a first intensity, and a light intensity of the second light emitting units is equal to a second intensity. In a second mode, the light intensity of the first light emitting unit is equal to a third intensity, and the light intensity of the second light emitting units is equal to a fourth intensity. The first intensity is greater than the third intensity, and the second intensity is less than the fourth intensity.

Backlight module and display device for privacy protection

The backlight module includes the following units. Multiple first light emitting units are disposed on a top surface of a transparent substrate. A beam angle of the first light emitting units is greater than or equal to 30 degrees and less than or equal to 45 degrees. Multiple second light emitting units and a light guide plate are disposed on a bottom surface of the transparent substrate. Each second light emitting unit is disposed in a respective hole of the light guide plate. A light intensity of the first light emitting units in a first mode is smaller than that in a second mode. A light intensity of the second light emitting units in the first mode is greater than that in the second mode. In this way, the purpose of privacy protection can be achieved.

Backlight module for protecting privacy

A trace structure for a touch panel having a transparent substrate with a touch sensing region and a border region surrounding the touch sensing region, the trace structure including: a plurality of traces disposed on the transparent substrate and within the border region; a plurality of bonding pads disposed in the border region of the transparent substrate, wherein each bonding pad has a first side and a second side, and the first side of each bonding pad is connected to a corresponding trace of the plurality of traces; and at least two trace extending portions extended toward an outer edge of the border region from the second side of two of the plurality of bonding pads.

Trace structure for the touch panel and electrical testing method

The present invention discloses a display device comprising a bezel, a cell, at least one film, a light bar and a composite backlight module. The composite backlight module comprises a plurality of connecting structures coupled with the bezel for fixing and protecting the cell, a containing space for containing the cell and the film, and a light guide portion for guiding light emitted by the light bar to a light exit surface of the composite backlight module. The composite backlight module is made of a same material by injection molding.
