ABSTRACT:
A method for installing a screen to a projection television receiver that uses a transmission-type screen such that the screen can be easily installed to and removed from the projection television receiver when multiple projection television receivers are combined to form a single large-scale multiple display system in which the receivers are stacked vertically and horizontally in an M.times.N rectangular configuration. Screen holding brackets installed in the cabinet body and screen clamping frames are used to secure the screen in place by inserting the screen clamping frames into the slight gap formed between the cabinet body and the screen holding brackets. Even when the screen clamping frames are inserted to the gap and slid to secure the screen, all movement of the clamping frames occurs within the dimensions of the cabinet body, thus making it easy to remove and install the screen even when multiple projection television receivers are combined in a single large-scale display system.
