Abstract

The invention discloses a display device capable of switching viewing angles, a display method and a manufacturing method thereof, and belongs to the field of display technology. The display device includes a display module and a guest-host effect box, and the guest-host effect box includes a first substrate, a second substrate, a display medium layer; the first substrate is provided with a first transparent electrode facing the display medium layer; the second substrate is provided with a second transparent electrode facing the display medium layer; the first transparent electrode is provided with a first alignment film layer facing the display medium layer, A second alignment film layer is arranged on the second transparent electrode facing the display medium layer; when no bias voltage is applied to the first transparent electrode and the second transparent electrode, the display mode is a narrow viewing angle mode; when a bias voltage is applied, the display mode is a wide viewing angle mode. perspective mode. Display methods include wide viewing angle mode and narrow viewing angle mode. The display device of the present invention is in a narrow viewing angle mode when it is not powered on, and is in a wide viewing angle mode when it is powered on, and does not require complicated driving, and the switching between wide and narrow viewing angles is convenient and effective.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display device capable of switching viewing angles, a display method, and a manufacturing method thereof. Background technique [0002] With the development of society, people are more and more dependent on electronic devices, and the current display devices are gradually developing in the direction of wide viewing angles, whether it is mobile terminal applications, desktop monitors or notebook computer applications. What follows is that when using some electronic devices, some information is not to be seen by others, so when people deal with confidential matters, in order to avoid commercial loss or embarrassment caused by screen information leakage, they often use narrow perspective mode. Therefore, in addition to the requirement for a wide viewing angle, in many occasions, the display device is also required to have a function of switching between a wide v...
