Liquid crystal display and method for operating the same
First Claim
1. A liquid crystal display, comprising:
- a liquid crystal display panel having a plurality of pixels on a display line;
a set of drivers for driving a set of pixels, the set of drivers receiving display data and providing video signals to the set of pixels;
a clock for providing a clock signal to the set of drivers to latch the display data based on a frequency of the clock signal, wherein the clock receives a feedback signal from the set of drivers prior to an end of the display data received by the set of drivers; and
a delay circuit for stopping the clock signal to the set of drivers based on the feedback signal, wherein the delay circuit stops the clock signal to the set of drivers after delaying for a first time period, the first time period being no less than a predetermined time period between the feedback signal and the end of the display data received by the set of drivers.

Abstract
A liquid crystal display includes a liquid crystal display panel having a plurality of pixels on a display line. A set of drivers drives a set of pixels, the set of drivers receiving display data and providing video signals to the set of pixels. A clock provides a clock signal to the set of drivers to latch the display data based on a frequency of the clock signal, and receives a feedback signal from the set of drivers prior to an end of the display data received by the set of drivers. A delay circuit stops the clock signal to the set of drivers, based on the feedback signal, after delaying for a first time period, that is no less than a predetermined time period between the feedback signal and the end of the display data received by the set of drivers.

5. A liquid crystal display, comprising:
-
a liquid crystal display panel having a plurality of pixels; a first set of drivers for driving a first set of pixels on a display line, the first set of drivers receiving display data and providing the first set of pixels with a first set of video signals; a second set of drivers for driving a second set of pixels, the second set of pixels receiving the display data and providing the second set of pixels with a second set of video signals, the second set of pixels being consecutive to the first set of pixels on the display line; a first clock for providing a first clock signal to the first set of drivers for the first set of drivers to latch the display data based on a frequency of the first clock signal, wherein the first clock receives a first feedback signal from the first set of drivers to determine when to stop providing the first clock signal to the first set of drivers; and a second clock for providing a second clock signal to the second set of drivers no later than a first transition, the first transition being an end of the display data received by the first set of drivers, the second set of drivers latching the display data based on a frequency of the second clock signal. - View Dependent Claims (6, 7, 8, 9, 10)

11. A liquid crystal display, comprising:
-
a liquid crystal display panel having a plurality of pixels; at least two sets of drivers for driving at least two sets of consecutive pixels in a display line, wherein two of the sets of drivers have a different number of drivers; two clocks for providing two clock signals, each clock signal being provided to at least one of the sets of drivers to latch display data based on a frequency of that clock signal, wherein a first clock of the two clocks receives a feedback signal from a first set of drivers before an end of the display data received by the first set of drivers; and a first delay circuit for stopping a first one of the two clock signals to the first set of drivers based on the feedback signal, wherein the first delay circuit stops the first clock signal to the first set of drivers after delaying for a first time period, the first time period being no less than a predetermined time period between the feedback signal and the end of the display data received by the first set of drivers. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A timing system for drivers of a liquid crystal display, comprising:
-
a first clock for providing a first clock signal to a first set of drivers for driving a first set of pixels of a display line, the first set of drivers driving the first set of pixels by latching display data based on a frequency of the first clock signal and providing a first set of video signals to the first set of pixels; a first delay circuit for stopping the first clock signal to the first set of drivers based on a first feedback signal received from the first set of drivers prior to an end of the display data received by the first set of drivers, wherein the first delay circuit stops the first clock signal to the first set of drivers after delaying for a first time period, the first time period being no less than a predetermined time period between the first feedback signal and the end of the display data received by the first set of drivers. - View Dependent Claims (19, 20)
