1. A wearable display system comprising:
a head mounted structure;
a first display module mounted at one side of the head mounted structure and providing a first content and a third content;
a second display module mounted at another side of the head mounted structure and providing a second content and the third content; and
an application processor connected to a first reception device of the first display module and a second reception device of the second display module via common transmission lanes for transmitting a differential data signal and a differential clock signal,
wherein the application processor transmits both the first content and the second content via the common transmission lanes,
wherein the common transmission lanes comprise a positive data transmission lane and a negative data transmission lane for the differential data signal,
wherein the common transmission lanes further comprise a positive clock transmission lane and a negative clock transmission lane for the differential clock signal, and
wherein each of the positive data transmission lane, the negative data transmission lane, the positive clock transmission lane, and the negative clock transmission lane is connected to both the first reception device and the second reception device,
wherein the first reception device is integrated and embedded in the first display module and the second reception device is integrated and embedded in the second display module,
wherein the first reception device is configured to buffer the first content and the third content transmitted through the common transmission lanes for the first display module,
wherein the second reception device is configured to buffer the second content and the third content for the second display module,
wherein the first display module and the second display module provide the third content simultaneously,
wherein a first image according to the third content provided to the first display module and a second image according to the third content provided to the second display module are identical to each other, and
wherein the first reception device comprises:
a second receiver having a second positive data input terminal connected to the positive data transmission lane and a second negative data input terminal connected to the negative data transmission lane;
a third termination resistor and a third termination switch connected in series between the second positive data input terminal and a second node;
a fourth termination resistor and a fourth termination switch connected in series between the second negative data input terminal and the second node; and
a second termination capacitor connected between the second node and a ground voltage.
