Abstract
An electronic display includes a housing and a display panel having a display surface that is visible through the housing. An inlet is provided to allow external air into the housing and an outlet is provided to allow external air out of the housing. There is a closable vent at the inlet or outlet and a temperature sensor. A controller is arranged to control opening and closing of the vent in response to the output of the temperature sensor.
Claims6
An electronic display comprising:
- a housing;
- a display panel within the housing and having a display surface that is visible through the housing;
- a heat exchanger that provides:
- (a) a first path through which internal air is circulated to cool the display panel;
- (b) a second path through which external air passes without mixing with said internal air;
- and (c) heat exchange between said internal air and external air;
- an inlet to allow external air into the heat exchanger;
- an outlet to allow external air out of the heat exchanger;
- a closable vent at said inlet or outlet;
- a temperature sensor;
- and
- a controller arranged to control opening and closing of said closable vent in response to an output of said temperature sensor, thereby to conserve heat generated within the display in cooler ambient conditions.
