Abstract

Embodiments of the present disclosure are directed to a display panel and a display device. A width of the fan-out wire positioned at the outer side is increased such that the impedance of the outer fan-out wire could be reduced. Furthermore, the second part of the second fan-out wire is bended in a direction away from the display region. This means that the second part only occupies the right/left redundant space and thus the second fan-out wire consumes less space of the lower side frame and the width of the fan-out region decreases. The present disclosure could achieve both comparatively low impedance of the fan-out wire and a narrow side frame.

Accordingly, a proportion of the area occupied by the light-transmissive portions is increased, leading to an enhancement in the light transmittance of the anti-peeping film. The presence of the light-blocking portions guarantees the light-blocking effect of the anti-peeping film. Therefore, both anti-peeping effectiveness and high light transmittance can be achieved at the same time.

Abstract

The present application provides a distributed system on panel (SOP) display panel and a display system. The distributed SOP display panel includes a plurality of display modules and a plurality of functional modules. Each display module includes a plurality of display units. The functional modules include first functional modules and a second functional module. The first functional modules are electrically connected to the display units in adjacent display modules, the second functional module is electrically connected to the plurality of display modules, in order to alleviate a technical problem of improper layout of system functions of a conventional SOP display device.

Abstract

Disclosed is a display device including a display panel, a reflective polarizing layer, a liquid crystal dimmer cell, and a first polarizing plate which are sequentially stacked, wherein a reflection surface of the reflective polarizing layer faces the liquid crystal dimmer cell, and a direction of a transmission axis of the reflective polarizing layer is same as a direction of a transmission axis of the first polarizing plate, so that not only a peep-proof function of the display device can be realized, but also ambient light with a large viewing angle can be reflected, which can further reduce the visibility of the display screen under the large viewing angle without affecting the display at the front viewing angle.
