METHOD OF TRANSFERRING DATA IN A DISPLAY DEVICE
First Claim
1. A method of transferring data between a timing controller and a plurality of source drivers in a display device, the method including:
- (a) setting a first source driver of the plurality of source drivers to convert first signals received from outside of the first source driver and having first voltage levels to second signals having second voltage levels;
(b) receiving, by the first source driver, a first test pattern from the timing controller;
(c) performing a test by the first source driver, based on the first test pattern, to determine whether an error has occurred in the first test pattern received at the first source driver; and
(d) when an error has occurred in the first test pattern received at the first source driver, adjusting, by the first source driver, an output level of a receiver of the first source driver, so that the first source driver converts the first signals to third signals having third voltage levels different from the second voltage levels.

Abstract
A method of transferring data between a timing controller and a plurality of source drivers in a display device is disclosed. The method includes: (a) setting a first source driver of the plurality of source drivers to convert first signals having first voltage levels to second signals having second voltage levels; (b) receiving, by the first source driver, a first test pattern from the timing controller; (c) performing a test by the first source driver, based on the first test pattern, to determine whether an error has occurred in the first test pattern; and (d) when an error has occurred in the first test pattern, adjusting, by the first source driver, an output level of a receiver of the first source driver, so that the first source driver converts the first signals to third signals having third voltage levels different from the second voltage levels.

11. A method of transferring data between a timing controller and a plurality of source drivers in a display device, the method including:
-
(a) receiving, by a first source driver of the plurality of source drivers, a first test signal; (b) converting, by the first source driver, the first test signal to a first TTL level signal; (c) performing, by the first source driver, error checking for the first TTL level signal; (d) if it is determined that an error has occurred, adjusting settings of the first source driver; and (e) repeating steps (a) through (d) until it is determined that no error has occurred. - View Dependent Claims (12, 13, 14)

15. A display device comprising:
-
a timing controller; and a plurality of source drivers, wherein a first source driver of the plurality of source drivers includes; a first receiver configured to receive a first test pattern from the timing controller; and a first error check unit configured to perform a test, based on the first test pattern, to determine whether an error has occurred in the first test pattern, wherein the first source driver is configured to adjust an output level of the first receiver when it is determined that an error has occurred in the first test pattern, so that signals output from the first receiver have different voltage levels after the adjustment than prior to the adjustment. - View Dependent Claims (16, 17, 18, 19, 20)
