Abstract
A liquid crystal display includes a display unit displaying an image in response to a driving signal, a driving unit outputting the driving signal to the display unit in response to a plurality of control signal, and a controller outputting the plurality of control signals and image data. The controller includes a plurality of timing controllers providing the image data and the plurality of control signals and a storage device. The plurality of timing controllers share the storage device and may be either connected in series or parallel.
Claims20
A liquid crystal display comprising:
- a display unit displaying an image in response to a driving signal;
- a driving unit outputting the driving signal to the display unit in response to a plurality of control signals;
- and
- a controller outputting the plurality of control signals and image data, wherein the controller comprises:
- a plurality of timing controllers providing the image data and the plurality of control signals;
- and
- a shared storage device, wherein the plurality of timing controllers are connected in series to one another and are each electrically connected to the shared storage device,
- wherein a current one of the timing controllers outputs a reset signal to a next one of the timing controllers after reading, from the shared storage device, a first driving setting value corresponding to the current timing controller and a second driving setting value corresponding to all the timing controllers,
- wherein the reset signal maintains a first logic level when the current timing controller has an error while communicating with the shared storage device, and otherwise transitions from the first logic level to a second other logic level.
A liquid crystal display comprising:
- a display unit displaying an image in response to a driving signal;
- a driver outputting the driving signal to the display unit in response to a plurality of control signals;
- and
- a controller outputting the plurality of control signal and image data, wherein the controller comprises:
- a plurality of timing controllers providing image data and the plurality of control signals;
- and
- a shared storage device, wherein the plurality of timing controllers are connected in parallel to one another and are each electrically connected to the shared storage device,
- wherein all the plurality of timing controllers output a reset signal to a same output node.
The liquid crystal display 17, wherein at least one of the timing controllers communicate with the storage device using an inter-integrated circuit (I2C) protocol.
A liquid crystal display comprising:
- a display unit displaying an image in response to a driving signal;
- a driving unit outputting the driving signal to the display unit in response to a plurality of control signals;
- a controller outputting the plurality of control signals, image data, wherein the controller comprises:
- a first timing controller receiving an externally provided reset signal and outputting a first ready completion signal;
- a second timing controller receiving the first ready completion signal for placing the second timing controller in one of an active and non-active state and outputting the first ready completion signal as a second ready completion signal to the first timing controller and as one of the control signals;
- a shared storage device storing driving setting values for each of the timing controllers, wherein the timing controllers are both connected to the shared storage device for retrieving their respective setting values;
- and
- a panel driving power unit outputting power to a panel of the display unit in response to receipt of the second ready completion signal.
