Classification: CPC G | IPC G

Claim 16:
17. The contrast enhancement device of claim 16, wherein the input test data include first through fourth input channel test data for the first through fourth channels with respect to the first display region, and fifth through eighth input channel test data for the fifth through eighth channels with respect to the second display region,
wherein the reference test data include first through eighth reference channel test data respectively corresponding to the first through eighth input channel test data,
wherein, in the diagnosis mode, the first through fourth channel process circuits respectively generate first through fourth output channel test data as the output test data by performing the contrast enhancement process on the first through fourth input channel test data in the first period, and respectively generate fifth through eighth output channel test data as the output test data by performing the contrast enhancement process on the fifth through eighth input channel test data in the second period, and
wherein the diagnosis circuit generates, as the diagnosis result data, first region diagnosis result data by respectively comparing the first through fourth output channel test data with the first through fourth reference channel test data, and second region diagnosis result data by respectively comparing the fifth through eighth output channel test data with the fifth through eighth reference channel test data.
