DISPLAY DRIVING CIRCUIT, DISPLAY DEVICE INCLUDING THE SAME, AND METHOD OF OPERATING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 17985599 titled 'DISPLAY DRIVING CIRCUIT, DISPLAY DEVICE INCLUDING THE SAME, AND METHOD OF OPERATING THE SAME
Simplified Explanation
The patent application describes a display driving circuit that includes several components to improve the performance of the circuit.
- The circuit includes a clock data recovery circuit that receives a data signal and generates a clock signal and a first output data signal.
- An eye margin test circuit is included, which samples the data signal using the clock signal and generates a second output data signal based on a vertical measurement voltage.
- A bit error check circuit is also included, which measures the bit error rate of the data signal based on the first and second output data signals.
- The clock data recovery circuit includes a jitter generator that generates jitter in the clock signal, with the amplitude of the jitter varying according to a horizontal control signal.
Potential applications of this technology:
- This display driving circuit can be used in various display devices such as televisions, computer monitors, and mobile devices.
- It can also be used in video walls, digital signage, and other large-scale display installations.
Problems solved by this technology:
- The circuit improves the accuracy and reliability of the data signal by using the clock data recovery circuit to generate a clock signal and output data signals.
- The eye margin test circuit helps to ensure that the data signal is sampled correctly, improving the overall quality of the display.
- The bit error check circuit allows for the measurement of the bit error rate, helping to identify and address any issues with the data signal.
Benefits of this technology:
- The use of the clock data recovery circuit and the jitter generator improves the performance of the display driving circuit, resulting in a more accurate and reliable display.
- The eye margin test circuit helps to optimize the sampling of the data signal, leading to improved visual quality.
- The bit error check circuit allows for the monitoring and measurement of the data signal, enabling quick identification and resolution of any issues.
