Electrowetting display element with radiation filter

An apparatus comprising:

• an electrowetting display element comprising:
• a radiation filter;
• a first support plate;
• a second support plate
• a first fluid;
• and
• a second fluid immiscible with the first fluid, the first fluid and the second fluid located between the first support plate and the second support plate;
• at least one processor;
• and
• at least one memory comprising computer program instructions operable to, with the at least one processor:
• determine, based on an input signal indicative of a characteristic of an input to the apparatus, that a predetermined condition for reduction of an exposure of the first fluid to incident light is satisfied;
• and, in response,
• generate an output signal to control the electrowetting display element to configure the first fluid in a retracted configuration with the first fluid at least partly overlapped by the radiation filter and with both the first fluid and the second fluid in contact with a surface of the first support plate.
