Abstract
A display securely decrypts an encrypted image signal. Pixels are disposed between the display substrate and cover in a display area, and provide light to a user in response to a drive signal. Control chiplets disposed between the display substrate and cover in the display area are each connected to one or more of the plurality of pixels. Each receives a respective control signal and produce respective drive signal(s) for the connected pixel(s). A decryption chiplet is disposed between the display substrate and cover. It includes means for receiving the encrypted image signal and a decryptor for decrypting the encrypted image signal to produce a respective control signal for each of the control chiplets.
Claims11
A display for securely decrypting an encrypted image signal, comprising:
- a) a display substrate having a display area, and an encapsulating cover affixed to the display substrate;
- b) a plurality of pixels disposed between the display substrate and the encapsulating cover in the display area for providing light to a user in response to a drive signal;
- c) a plurality of control chiplets, each of which is disposed between the display substrate and the encapsulating cover and is disposed in the display area, each including a respective chiplet substrate separate and distinct from the display substrate, connected to one or more of the plurality of pixels, for receiving a respective control signal and producing respective drive signal(s) for the connected pixel(s);
- and
- d) exactly one decryption chiplet, which is disposed between the display substrate and the encapsulating cover and is disposed in the display area, that includes:
- i) a chiplet substrate separate and distinct from the display substrate;
- ii) means for receiving the encrypted image signal;
- and
- iii) a decryptor for decrypting the encrypted image signal to produce a respective control signal for each of the control chiplets and transmitting each control signal to the corresponding control chiplet;
- wherein there are no other decryption chiplets present in the display.
