In search of a LCD...

Hi,

does anyone know of TFT-diplay, which

    * is mounted on a PCB like LCD7/4/3 is
    * PCB is not larger than that of the Beaglebone Black
    * is compatible to the Beaglebone Black
    * is of same of higher pixel density of the LCD7/4/3

(background: I need to add an display to a Beaglebone black, which
is already in a metal case.)

Thank you very much in advance for any help!

Best regards,
mcc
