CROSS REFERENCE TO RELATED APPLICATIONS

This application is a U.S. National Phase of International Patent Application No. PCT/JP2018/029340 filed on Aug. 6, 2018, which claims priority benefit of Japanese Patent Application No. JP 2017-178527 filed in the Japan Patent Office on Sep. 19, 2017. Each of the above-referenced applications is hereby incorporated herein by reference in its entirety.

TECHNICAL FIELD

The present disclosure relates to a display apparatus and a driving method of a display apparatus.

BACKGROUND ART

As a display apparatus that presents information in a visually recognizable manner, there is a projection-type display apparatus that presents information by projecting an image on a projection plane, like a so-called projector. For example, PTL 1 discloses an example of the projection-type display apparatus. Further, in recent years, various projection-type display apparatuses to each of which an LCOS (Liquid crystal on silicon, LCOS is a registered trademark) technology is applied have been proposed.

SUMMARY OF THE INVENTION

Problems to be Solved by the Invention

Examples of the projection-type display apparatus to which the LCOS technology is applied include a display apparatus employing a single-panel system utilizing one sheet of LCOS and a display apparatus employing a three-panel system utilizing three sheets of LCOS. In the three-panel system, for example, images of different colors (e.g., RGB) of the respective three sheets of LCOS are generated, and the images generated by the respective sheets of LCOS are combined by an optical system, such as a prism, to be presented. In contrast, in the single-panel system, images of a plurality of colors are presented by the one sheet of LCOS. For this reason, in the display apparatus employing the single-panel system, there is a case where a drive system called “color sequential drive” that sequentially displays each of images of a plurality of colors in time division is adopted.

Thus, the present disclosure proposes a technique that enables an image to be displayed in a more suitable manner, in a case where the color sequential drive is adopted.

Means for Solving the Problem

According to the present disclosure, there is provided a display apparatus including: an addition section that adds a dither signal to a digital image signal for each of a plurality of color components, the digital image signal being generated on a basis of each of the plurality of color components different from each other, and inputted in predetermined order for each sub-frame included in a frame; a conversion section that performs digital to analog conversion of converting the digital image signal to which the dither signal is added into an analog image signal; and a control section that controls a pattern of the dither signal, at each predetermined cycle including a plurality of the sub-frames, depending on the order in which the digital image signal for each of the color components is inputted, within the frame.

Further, according to the present disclosure, there is provided a display apparatus including: a signal processing section that controls a polarity of a data signal based on an image signal for each of a plurality of color components, the image signal being generated on a basis of each of the plurality of color components different from each other, and inputted in predetermined order for each sub-frame included in a frame, at predetermined cycle including a plurality of sub-frames; and a control section that controls operation of a pixel on a basis of the data signal having the controlled polarity.

Furthermore, according to the present disclosure, there is provided a driving method of a display apparatus, the driving method including: causing a computer to add a dither signal to a digital image signal for each of a plurality of color components, the digital image signal being generated on a basis of each of the plurality of color components different from each other, and inputted in predetermined order for each sub-frame included in a frame; causing the computer to perform digital to analog conversion of converting the digital image signal to which the dither signal is added into an analog image signal; and causing the computer to control a pattern of the dither signal, at each predetermined cycle including a plurality of the sub-frames, depending on the order in which the digital image signal for each of the color components is inputted, within the frame.

Still further, according to the present disclosure, there is provided a driving method of a display apparatus, the driving method including: causing a computer to control a polarity of a data signal based on an image signal for each of a plurality of color components, the image signal being generated on a basis of each of the plurality of color components different from each other, and inputted in predetermined order for each sub-frame included in a frame, at predetermined cycle including a plurality of sub-frames; and causing the computer to control operation of a pixel on a basis of the data signal having the controlled polarity.

Effects of the Invention

As described above, according to the present disclosure, there is provided a technique that enables an image to be displayed in a more suitable manner, in a case where color sequential drive is adopted.

It is to be noted that the effect described above is not necessarily limitative, and any of effects described in the present specification or other effect conceivable from the present specification may be produced together with the above-described effect or in place of the above-described effect.
