A display device 100 that comprises at least one display unit 108 (such as an OLED display) configured to display an image and at least one layer unit 104 that is operable to change the quantity of light rays 112 to pass through the layer unit 104, wherein the layer unit 104 comprises metal halide perovskite. The layer unit 104 may be configured to generate a current and/or voltage when light rays 112 pass through the layer unit 104 and/or change the quantity of light rays 112 to pass through the layer unit in a first direction when the wavelength and/or quantity of light rays 112 is changed. A display system for a vehicle is also disclosed that comprises one or more display devices, a control unit and a light generating unit that sends light rays (112b, fig.4) with a determined wavelength and/or intensity to at least one layer unit or each layer unit of the one or more display devices.
