Abstract: A display device includes an emission circuit, a first control circuit and a second control circuit. The emission circuit is coupled to a first node and is configured to emit light based on an emission signal and a voltage level of the first node. The first control circuit is configured to charge the first node based on a sweep signal and the emission signal. The second control circuit is configured to discharge the first node based on the sweep signal and the emission signal.

Abstract: Disclosed is a pixel circuit. A pulse width signal generator provides a pulse width signal to a control terminal of a light-emitting control switch on a drive current path of a drive current generator. A multiple lighting controller adjusts the pulse width signal provided by the pulse width signal generator according to a multiple emission control signal to allow a light-emitting element to perform multi-emission.

Abstract: A computer system having a firmware verification mechanism includes a plurality of non-transitory storage circuits and a processing circuit. Each of the non-transitory storage circuits stores at least one of a plurality of strings not generated by using a random number. The processing circuit is configured to perform steps for firmware verification. The firmware verification includes the following steps. A to-be verified block of the device firmware is loaded. A plurality of public key composition strings of the strings are retrieved from the non-transitory storage circuits to combine the public key composition strings into a public key. The to-be verified block is compared with the public key to determine whether the to-be verified block is generated based on a private key calculated from the public key. When the to-be verified block is generated by the private key, it continues to perform a chain of trust verification.
