Abstract
A timing controller includes an interface controller that reads out a current identification code and current address information of the current identification code. A data comparator compares a previous identification code stored in a memory provided in the timing controller with the current identification code. If the current identification code is different from the previous identification code, the interface controller reads out current parameter data corresponding to the current identification code from the memory and a data processor processes image data by using the current parameter data. The timing controller recognizes the update state of the parameter data stored in the memory and processes the image data by using the updated parameter data.
Claims24
A method of driving a timing controller for a display unit, the method comprising:
- reading from memory a currently supplied identification code and its current address information;
- comparing an identification code previously stored in memory with the currently supplied identification code;
- reading out current parameter data corresponding to the currently supplied identification code according to the comparing result;
- and
- processing a currently supplied data signal using the current parameter data.
A timing controller comprising:
- an interface controller periodically reading out a current identification code, address information of the current identification code, and current parameter data corresponding to the current identification code in response to a first control signal;
- a first storage area storing a previous identification code and a second storage area storing the current identification code;
- a data comparator comparing the previous identification code with the current identification code so as to output the first control signal according to the comparing result between the previous identification code and the current identification code;
- and
- a data processor processing a data signal by using the current parameter data provided from the interface controller.
A display device comprising:
- a display unit displaying an image in response to a gate signal and a data signal;
- a gate driver providing the gate signal to the display unit in response to a gate control signal;
- a data driver providing the data signal to the display unit in response to a data control signal;
- a memory including a first storage area storing address information therein and a second storage area storing parameter data and a identification code therein;
- a timing controller providing the gate and data control signals to the gate and data drivers in response to external control signals, respectively, and processing image data by using the parameter data stored in the memory so as to transmit the processed image data to the data driver;
- and
- a digital interface interfacing between the memory and the timing controller,
- the timing controller comprising:
- an interface controller periodically reading out a current identification code and address information of the current identification code from the memory, and reading out current parameter data corresponding to the current identification code from the memory in response to a first control signal;
- a volatile memory including a first storage area storing a previous identification code and a second storage area storing the current identification code;
- a data comparator comparing the previous identification code with the current identification code so as to output the first control signal when the previous identification code is different from the current identification code;
- and
- a data processor processing the image data by using the current parameter data provided from the interface controller.
