September 11, 2014



By a News Reporter-Staff News Editor at Computer Weekly News -- From Washington, D.C., VerticalNews journalists report that a patent application by the inventors Zhang, Min (Beijing, CN); Zhang, Zhenhua (Beijing, CN); Shang, Ke (Beijing, CN), filed on February 21, 2013, was made available online on August 28, 2014.

The patent's assignee is Beijing Lenovo Software Ltd.

News editors obtained the following quote from the background information supplied by the inventors: "The existing display screen causes chromatic aberration on the displayed image due to reasons such as the used material or display structure, and thus reducing the display quality.

"For example, a touch-screen displayer based on a thin-film sensor may cause to display yellowish due to the aging of the material, and therefore it may cause chromatic aberration.

"As for an interference reflective display screen, since it is an interference modulation based reflective technique, the interference reflective display screen uses the ambient light as light sources and does not need backlight. The interference reflective display screen may be adjusted in accordance with the surrounding light conditions automatically, and a user may view it under almost all the environments. The interference reflective display screen adopts a set of microscopic display structures, which is referred as a pixel unit. Currently, since the positions of pixels are set unreasonably in a display screen, the display effect of a display screen is affected."

As a supplement to the background information on this patent application, VerticalNews correspondents also obtained the inventors' summary information for this patent application: "In order to solve the above technical problems, it is provided a display adjusting method, system and electronic device in an embodiment of the disclosure, for improving the display effect of a display screen. The technical solutions are as follows.

"In an embodiment of the disclosure, it is provided a display adjusting method applied to an electronic device including a display unit which has a touch function and includes a touch sensing unit adapted to receive a touch operation of a user, where the method includes:

"judging whether chromatic aberration is generated in the touch sensing unit to obtain a first judgment result;

"judging whether the chromatic aberration meets a preset condition to obtain a second judgment result in the case where the first judgment result indicates that the chromatic aberration is generated in the touch sensing unit; and

"adjusting display parameters of the display unit based on the chromatic aberration to correct the chromatic aberration in the case where the second judgment result indicates that the chromatic aberration meets the preset condition.

"In an embodiment of the disclosure, it is provided another display adjusting method, and the method includes:

"acquiring first relative position information between a first pixel unit of an interference reflective display screen and a first area in a range illuminated by the first pixel unit; and

"adjusting an angle of the first pixel unit in accordance with the first relative position information.

"In an embodiment of the disclosure, it is provided a display adjusting system including a first acquiring unit and a first adjusting unit, where:

"the first acquiring unit is adapted to acquire first relative position information between a first pixel unit of an interference reflective display screen and a first area in a range illuminated by the first pixel unit; and

"the first adjusting unit is adapted to adjust the angle of the first pixel unit in accordance with the first relative position information.

"In an embodiment of the disclosure, it is provided an electronic device including a display unit which has touch ability and includes a touch sensing unit adapted to receive a touch operation of a user, wherein the electronic device further includes a display adjusting apparatus which includes:

"a first judging module, adapted to judge whether chromatic aberration is generated in the touch sensing unit to obtain a first judgment result;

"a second judging module, adapted to judge whether the chromatic aberration meets a preset condition to obtain a second judgment result in the case where the first judgment result indicates that the chromatic aberration is generated in the touch sensing unit; and

"an adjusting module, adapted to adjust display parameters of the display unit based on the chromatic aberration to correct the chromatic aberration in the case where the second judgment result indicates that the chromatic aberration meets the preset condition.

"According to the technical solutions provided in the embodiments of the disclosure, the problem of a chromatic aberration of the display screen caused by reasons such as the used material or display structure can be corrected, thus improving the display effect.
