Display device

A display device, comprising a signal source end, a display end and a transmission part, wherein the signal source end is separately arranged from the display end and the signal source end and the display end are connected through the transmission part;

• wherein,
• the signal source end comprises:
• a first control circuit for outputting a V BY ONE data signal;
• and
• a first photoelectric converter connected to the first control circuit, wherein the first photoelectric converter is configured to obtain the V BY ONE data signal and convert the V BY ONE data signal into an optical signal for transmission;
• wherein the transmission part comprises an optical fiber;
• and
• wherein the display end comprises:
• a second photoelectric converter connected to the first photoelectric converter through the optical fiber, wherein the second photoelectric converter is configured to convert the received optical signal into a corresponding V BY ONE data signal;
• and
• a display module connected to the second photoelectric converter, wherein the display module is configured to obtain the V BY ONE data signal for image display,
• wherein the signal source end further comprises:
• a first power source module;
