When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0073] In current in-vehicle displays, there is an increasing demand for active anti-peeping, which helps improve privacy and driving safety. However, current active anti-peeping technology requires new driving circuits and auxiliary devices to achieve brightness control of light-emitting units in anti-peeping areas and non-anti-peeping areas, which increases the complexity and cost of the circuit.

[0074] Based on this, the present application provides a display panel solution, as detailed in the following embodiments.

[0077] The display panel 100 further includes a first wiring 4 , which is electrically connected to the isolation structure 2 located in the privacy protection area 101 . The first wiring 4 is used to transmit a power signal.

[0078] Among them, an isolation structure 2 is set between the light-emitting units 3 to separate the functional film layers of adjacent light-emitting units 3. In this way, in the evaporation process of multiple functional film layers, it is only necessary to perform whole-surface evaporation on the display panel 100, without the need to use a mask plate to evaporate the area where the light-emitting unit 3 is located to form a functional film layer. Therefore, the process of evaporation using the isolation structure 2 does not need to consider the positioning accuracy during evaporation, so that the gap between the light-emitting units 3 can be designed to be smaller in size to increase the pixel density.

[0079] The second electrode 33 is electrically connected to the isolation structure 2 , so that the isolation structure 2 connects the second electrodes 33 of different light-emitting units 3 , thereby making the isolation structure 2 and the second electrodes 33 of the light-emitting units 3 form a common electrode for driving.
