Abstract
A liquid crystal display includes a display panel, a first sensor, a light emitting unit, a second sensor and a controller. The first sensor is provided in the display panel to detect input light, which is incident from an exterior. The second sensor is provided in the display panel or the light emitting unit so as to detect output light generated from the light emitting unit. The controller analyzes the input light detected by the first sensor and controls the light emitting unit so as to generate the output unit corresponding to an analysis value.
Claims28
A liquid crystal display device comprising:
- a display panel that displays an image using a liquid crystal layer;
- a first sensor provided in the display panel to detect input light incident from outside the display panel;
- a light emitting unit having at least two different light sources and providing output light having various colors to the display panel;
- a second sensor for detecting the output light provided to the display panel;
- and
- a controller for analyzing the input light detected by the first sensor, calculating a target value for output light to be delivered to the display panel, individually controlling the light sources to generate colored lights corresponding to the target value of the output light, and inspecting whether the output light detected by the second sensor satisfies the target value.
A liquid crystal display device comprising:
- a first substrate having a display area where pixel areas are defined and a peripheral area surrounding the display area;
- a second substrate facing the first substrate;
- a liquid crystal layer interposed between the first and second substrates;
- and
- a sensor provided in the peripheral area so as to detect input light incident through the second substrate,
- wherein the sensor comprises:
- a first liquid crystal control electrode formed on the first substrate in adjacent to the liquid crystal layer;
- and
- a second liquid crystal control electrode formed on the second substrate in adjacent to the liquid crystal layer, the second liquid crystal control electrode interacting with the first liquid crystal control electrode so as to apply an electric field to the liquid crystal layer.
A method of driving a liquid crystal display device, the method comprising:
- detecting input light incident into a display panel having a liquid crystal layer;
- obtaining an analysis value for the detected input light;
- calculating a target value corrected according to the analysis value;
- generating colored light corresponding to the target value by individually controlling at least two different light sources that generate colored lights different from each other;
- and
- providing output light generated by the colored lights to the display panel.
