A liquid crystal panel module, a backlight module and a liquid crystal display (LCD) are provided. The liquid crystal panel module includes a liquid crystal panel and a diffraction grating layer. The liquid crystal panel has a plurality of pixels. The diffraction grating layer is disposed on the liquid crystal panel, and a maximum period of a grating of the diffraction grating layer is smaller than 1/10 of a size of the pixels. The backlight module includes a light guide plate, a light emitting element and a diffraction grating film. A light provided by the light emitting element emits from a light emitting surface of the light guide plate and is bended towards the light emitting element after passing through the diffraction grating film. The liquid crystal panel module and the backlight module can be applied to the LCD together or individually.

A pixel signal for a pixel has an initial voltage during a frame period. The pixel signal is driven from the initial voltage to an intermediate voltage larger than the initial voltage during the frame period, and the pixel signal is maintained at the intermediate voltage for a time interval. After the time interval, the pixel signal is driven from the intermediate voltage to a target voltage larger than the intermediate voltage during the frame period.

A driving unit for a display device includes a buffer to provide first frame data and second frame data and a timing controller. The timing controller includes a first overdrive data generation unit responsive to the first frame data to output first overdrive frame data to the display device and a second overdrive data generation unit in response to the second frame data to output second overdrive frame data. The timing controller also includes a delay unit to delay the second current overdrive frame data by a delay time period to output the second current overdrive frame data to the display device after the delay time period.

A method, which establishes a voice communications link through the internet community, includes the step of configuring a gateway to use a mapping table to translate input identification data of a called party to a corresponding internet protocol address of another gateway associated with the called party. The method is relatively simple as compared to existing voice over internet protocols.

A method for driving a pixel includes driving the pixel with a first gray level and a second gray level within a first sub-frame period and a second sub-frame period of a first frame period, respectively, driving the pixel with a third gray level and a fourth gray level within a first sub-frame period and a second sub-frame period of a second frame period, respectively, and adjusting the third gray level and the fourth grey level such that the luminance of the adjusted fourth grey level is similar to the luminance of the second grey level.

There is provided a portable optical touch system including a first image sensing module, a second image sensing module, a connecting device, a communication interface and a processing circuit. The two image sensing modules have partially overlapped field of views and the partially overlapped field of views is for defining a touch region. The connecting device is configured to adjust or fix a distance between the first and second image sensing modules. When an object is in the touch region, the processing circuit calculates a position of the object according to images of the object acquired by the two image sensing modules and outputs information of the position of the object through the communication interface.

A method of operating a display includes deriving first pixel data for overdriving pixel circuits of the display from initial gray levels to target gray levels based on values in the first and second lookup tables, rendering the second lookup table unavailable in memory in response to a change in a temperature of the display, and deriving second pixel data using the first lookup table for overdriving the pixel circuits when the second lookup table is unavailable in the memory.

A method of operating a display includes providing light having a luminance that varies periodically, overdriving a pixel circuit of the display, and modulating the light using the pixel circuit to generate modulated light. The amount of overdrive and the phase of the light relative to the overdriving of the pixel circuit are controlled such that the modulated light has a predetermined level of uniformity.

摘要:
A method of displaying image data, which can mitigate a double-boundary problem and improve MPRT, includes the steps of: receiving a plurality of frame data of a pixel; correcting subframe data of two of the plurality frame data; and sequentially displaying each of the subframe data of the plurality frame data.
