Disclosed is a digital eyesight device, which comprises an ASIC (Application Specific Integrated Circuit) which includes a data storing part which stores a graphic data on an eyesight measurement table, an internal memory part which retrieves a graphic data from the data storing part; an embedded processor which has an internal processor part processing a graphic data, an external graphic processor which converts a 1-channel type graphic data processed by the embedded processor into a 2-channel type graphic data, a first bus which is connected between the embedded processor and the external graphic processor and is connected with the embedded processor in a signal transmission way, and a second bus which is electrically connected with the external graphic processor, said ASIC having an interface function interfacing the signal of the embedded processor to the external graphic processor and converting a 1-port 2-channel graphic data generated by the external graphic processor into a 2-port 2-channel graphic data; and a large size panel which receives a 2-port 2-channel type graphic data from the ASIC and displays it. |
