摘要： A method for determining whether or not a display panel is a duplicate is provided. The method includes: generating, by a code generator in an electronic module, a code, the electronic module including a plurality of electronic components; transmitting, by the code generator, the code to each of a first sequence generator in the electronic module and a second sequence generator in a display panel, the display panel being configured to be mounted to the electronic module; generating, by the first sequence generator, a first response value, and transmitting the first response value to a certification component in the electronic module; generating, by the second sequence generator, a second response value, and transmitting the second response value to the certification component; and comparing, by the certification component, the received first response value and the received second response value.

摘要： A display device includes an oscillator which generates a reference clock signal having a frequency corresponding to frequency information provided from an external device, a register which stores a signal parameter for the reference clock signal, and the signal parameter indicates the number of pulses of the reference clock signal included in one horizontal time, a data driver which applies data signals to data lines connected to pixels based on the one horizontal time, and a controller which changes the signal parameter based on a change in the frequency of the reference clock signal in a way such that the one horizontal time is maintained substantially constant.
