Patent ID: 8723777

Claim:
A panel control device for outputting video data and a control signal to a liquid crystal display device, the panel control device comprising: a programmable array configured to receive source video data, a synchronization signal, and to operate in accordance with a configuration code including information on specifications of the video data and the control signal of the liquid crystal display device; and a first memory configured to input/output data to/from the programmable array, wherein: the programmable array includes a plurality of first-type elements arranged in a matrix, at least one second-type element and at least one bus line, at least one of the plurality of first-type elements includes: a second memory configured to store a first designated configuration code for the at least one of the plurality of first-type elements as first control information; a calculator configured to operate based on the first control information output from the second memory, and to receive data from the bus line; a first register configured to hold output data of the calculator; and an output circuit configured to output, to the bus line, output data from the first register, and the second-type element includes: a third memory configured to store a second designated configuration code for the second-type element as second control information, a counter configured to receive the synchronization signal from the bus line, and to operate based on the second control information output from the third memory, a second register and a third register; a first comparator configured to compare outputs from the counter and the second register, and to output a compared result to the bus line; and a second comparator configured to compare outputs from the counter and the third register, and to output a compared result to the bus line.
