Calculator projection display |
摘要 |
A projection display (10) for an electronic data processing device (14) for use in conjunction with an overhead projector (12) is provided. The projection display (10) includes a display with a light transmitting screen (30), and the screen (30) is framed by a uniquely constructed housing (32). The housing (32) defines a free convection air channel below the screen (30) to conduct a cooling air flow. The air flow in the free convection air channel substantially eliminates the problem of image deterioration due to screen overheating.
