Claim 5:
6. The display device according to claim 1, wherein each of the driving circuits comprises:
a serial input and output interface configured to connect the serial control lines and the sharing data line, wherein the controller addresses the driving circuit and reads data of the driving circuit through the serial control lines, and the controller sends information to the driving circuit through the sharing data line;
a timing sequence controller connected to the serial input and output interface, and configured to decode and deserialize data, store the decoded and deserialized data in a first storage unit; and control outputs of a pulse amplitude modulation unit and a pulse width modulation unit through the data stored in the first storage unit, to control the respective indicator lights connected to the driving circuit;
the first storage unit connected to the timing sequence controller, and configured to store data;
a second storage unit connected to the timing sequence controller, and configured to store an address;
the pulse amplitude modulation unit connected to the timing sequence controller, and configured to output Y PAM signals under a control of the timing sequence controller;
the pulse width modulation unit connected to the timing sequence controller, and configured to output Y PWM signals under a control of the timing sequence controller;
a current source driver with an adjustable gain, connected to the pulse amplitude modulation unit and the pulse width modulation unit, and configured to output Y current driving signals based on the Y PAM signals and the Y PWM signals to drive the display array set connected to the driving circuit, wherein a power of each of the current driving signals is controlled by one PAM signal and one PWM signal that correspond to the current driving signal; and
a channel status monitoring circuit configured to monitor circuit information of respective Y current driving signals.
