In accordance with an example embodiment of the present invention, an apparatus is disclosed. The apparatus includes a display section and a touch panel section. The touch panel section is adjacent the display section. The touch panel section includes a first layer, a second layer and a third layer. The first layer includes a conductive material. The second layer includes a bottom guard layer. The third layer includes a top guard layer. The first layer is between the second and third layers. The conductive material includes a color filter and a black matrix.

Within one gate selection time interval: first pixel information is driven from a source line to a liquid crystal LC element of a pixel; and second pixel information is driven from the source line to a memory element of the pixel; and the second pixel information is driven from the memory element of the pixel to the LC element of the pixel. Respecting a second pixel, similar occurs for third and fourth pixel information within a second gate selection time interval, such that the second pixel information is driven from the memory element of the first pixel to the LC element of the first pixel simultaneous with the third pixel information being driven from the source line to the LC element of the second pixel. Such simultaneous driving enables a faster refresh rate and/or larger displays. Various circuit-specific implementations are shown.

Overdriving with memory-in-pixel

An apparatus including at least one light source; a selective attenuation element, used for a plurality of adjacent pixels and configured to attenuate light from the at least one light source; and a group of adjacent mono-chrome light filters, used for the plurality of adjacent pixels, the group including a first mono-chrome light filter, for a first one of the plurality of adjacent pixels, configured to filter light transmitted via the selective attenuation element for the first one of the adjacent pixels; and a second mono-chrome light filter, for a second one of the plurality of adjacent pixels, configured to filter light transmitted via the selective attenuation element for the second one of the adjacent pixels.

Display apparatus

An apparatus with a first and second touch screen, where the first touch screen has a plurality of first touch sensors formed as a first grid of rows and columns and the second touch screen has a plurality of second touch sensors formed as a second grid of rows and columns. A first processor detects touch areas by scanning through the first touch sensors in a predetermined order along the rows and columns. A second processor detects touch areas by scanning through the second touch sensors in a predetermined order along the rows and columns. A controller causes that the first and second processors scan the first and second grids synchronized such that when the first and second touch screens are arranged side by side, neighboring first and second touch sensors are scanned substantially simultaneously.

Touch detection

It is disclosed to measure the impedance of a read-out line. The read-out line includes at least two cascaded electrical circuit segments, each electrical circuit segment including two longitudinal arms, wherein one of the longitudinal arms includes an electrical component, and a lateral arm including a switch configured to close in the presence of an object in the vicinity of the switch. The measured impedance of the read-out line can be compared to a preset value corresponding to an allowable value of the impedance of the read-out line.

Touch controller with read-out line

An apparatus comprises at least one component arranged to be supplied with at least one analog value. In order to enable a testing of the at least one component, the apparatus further comprises at least one comparator configured to compare at least one analog value, which corresponds to at least one analog value supplied to the at least one component, with at least one analog value read from the at least one component. The comparator is moreover configured to provide a result of the comparison.

Componet supplied with an analog value

The present invention provides methods and modules allowing for mapping of interface signals at for instance multi-line buses. A mapping of internal signal order schemes to external signal order schemes is enabled such that upon configuration any interface signals may carried on any lines of a multi-line bus. The configurability may obtained by the implementation of mapping logics and mapping algorithms, which associates external interface terminal to signal association to internal interface terminal to signal association in a configurable manner.

In a method for adjusting a refresh rate of a display, a current status of at least one lighting criterion is determined. The refresh rate is then adjusted depending on this determined status. A display module and an electronic device, respectively, comprise a display and a processing component adapted to perform such an adjustment. In a software program product, a software code is stored in a readable medium, the software code performing such an adjustment of the refresh rate of a display when being executed by a processor.

Image or other data is stored in a memory. A first validation parameter (e.g., a checksum) is determined for the data stored in the memory at a first time, and stored. A second validation parameter is determined for the data stored in the memory at a second time, and also stored. The stored first and second validation parameters are then compared. In this manner, corruption of data in the memory may be determined by the comparison. In the case where the compared first and second validation parameters are not identical (within a threshold in certain embodiments), the data stored in the memory is updated. As applied to graphical image data, this is seen as advantageous over the prior art approach of periodically updating a frame memory even when no new image data set is present. Apparatus and computer program products are also detailed.
