Abstract

Claims (36)

1. A method comprising:

receiving, by a processor, a change event notification associated with a change to a new overdrive setting of a liquid crystal display;

in response to the receiving the change event notification, determining a first pin value of a first pin of a timing controller and a second pin value of a second pin of the timing controller, wherein the first pin value and the second pin value are associated with the new overdrive setting of the liquid crystal display;

subsequent to the determining the first pin value and the second pin value, determining whether a vertical blank period is starting; and

in response to determining that the vertical blank period is starting, applying the first pin value to the first pin of the timing controller and applying the second pin value to the second pin of the timing controller of the liquid crystal display.

2. The method of claim 1 , wherein the change event notification is generated when a user changes an overdrive setting at an on-screen display menu to the new overdrive setting.

3. The method of claim 1 , wherein the change to the new overdrive setting is a change in response time of the liquid crystal display.

4. The method of claim 1 , wherein the first pin and the second pin is associated with the timing controller of the liquid crystal display.

5. The method of claim 1 , wherein the determining the first pin value and the second pin value is based on a lookup table associated with overdrive settings.

6. The method of claim 5 , wherein the lookup table is stored at a memory associated with the timing controller.

7. The method of claim 1 , wherein the liquid crystal display operates using the new overdrive setting at a vertical active period after the vertical blank period.

8. A monitor of an information handling system, comprising:

a timing controller coupled to a liquid crystal display panel; and

a scaler unit coupled to timing controller, the scaler unit configured to:

receive a change event notification associated with a change to a new overdrive setting of the liquid crystal display panel;

in response to the receipt of the change event notification, determine a set of lookup table values associated with the change to the new overdrive setting of the liquid crystal display panel;

subsequent to the determination of the set of lookup table values, determine a size of data to be transmitted based on the set of lookup table values;

divide the data to be transmitted into data portions based on factors that include the size of the data to be transmitted, speed of an inter-integrated circuit bus, or length of a vertical blank period, wherein the inter-integrated circuit bus is coupled to the scaler unit and the liquid crystal display panel; and

transmit one of the data portions during the vertical blank period via the inter-integrated circuit bus.

9. The monitor of the information handling system of claim 8 , wherein the change to the new overdrive setting is a change in response time of the liquid crystal display panel.

10. The monitor of the information handling system of claim 8 , further comprising stopping the transmission of the one data portion at end of the vertical blank period.

11. The monitor of the information handling system of claim 8 , wherein the scaler unit is further configured to detect the change to the new overdrive setting.

12. The monitor of the information handling system of claim 8 , wherein the liquid crystal display panel is configured to use the new overdrive setting at a start of a vertical active period after transmission of a last data portion of the data portions.

13. The monitor of the information handling system of claim 8 , wherein the scaler unit is further configured to transmit another data portion of the data portions at a start of another vertical blank period.

14. A method comprising:

receiving, by a processor, a change event notification associated with a new overdrive setting of a liquid crystal display;

in response to receiving the change event notification, determining a set of lookup table values associated with the new overdrive setting of the liquid crystal display;

subsequent to the determining the set of lookup table values associated, determining a size of data to be transmitted based on the set of lookup table values;

dividing the data to be transmitted into data portions based on factor that include size of the data to be transmitted, speed of an inter-integrated circuit bus, and length of a vertical blank period; and

transmitting a data portion of the data portions during the vertical blank period via the inter-integrated circuit bus.

15. The method of claim 14 , wherein the change to the new overdrive setting is a change in response time of the liquid crystal display.

16. The method of claim 14 , further comprising stopping the transmitting of the data portion at end of the vertical blank period.

17. The method of claim 14 , further comprising transmitting another portion of the data portions during another vertical blank period.

18. The method of claim 14 , further comprising determining whether the vertical blank period is starting prior to transmitting the data portion.

19. The method of claim 14 , further comprising stopping the transmitting of the data portion when the vertical blank period is ending.

20. The method of claim 14 , wherein the liquid crystal display starts operating at the new overdrive setting at a beginning of a vertical active frame after transmission of the data portions.
