Problems solved by technology
[0007] However, the technique described in Unexamined Japanese Patent Application Laid-Open Publication No. 2005-173193 has a problem in that manufacturing cost increases to ensure reliability because of complicated control and Luminescence cycle control, etc., using different feedback control, that is, using multiple algorithms
Moreover, complex algorithm control causes an increase in power consumption of the driver IC, resulting in a decrease in power performance
[0008] With the technology disclosed in Unexamined Japanese Patent Application Publication No. 2007-240617, when there is light reflected by external light or by relatively strong external light from another light source such as sunlight or a fluorescent lamp in a room, etc. It is difficult to detect small changes in refractive index based on deformation when the noise caused by scattering

A display device includes a flexible substrate, a display unit including a plurality of light-emitting elements arranged at the substrate and configured to display an image according to an image signal, a displacement sensor provided to a front surface or a back surface of the substrate and configured to detect a curved state of the substrate, and a pixel shift control unit configured to control pixel shifting of the image displayed in the display unit when a curve of the substrate is detected by the displacement sensor. According to the invention, the device can reliably prevent the display performance of flexible display device from deteriorating.
Description
[0001] Cross References to Related Applications [0002] The present application contains subject matter related to the disclosure of Japanese Priority Patent Application JP2009-247517 filed in the Japan Patent Office on Oct. 28, 2009, the entire content of which is hereby incorporated by reference. technical field [0003] The present invention relates to a display device and a method of controlling the display device. Background technique [0004] In recent years, ensuring the reliability of display elements in display devices has become a very important challenge. In particular, ensuring structural and mechanical reliability or reliability related to display performance remains an important issue as in the past. [0005] For example, Unexamined Japanese Patent Application Laid-Open Publication No. 2005-173193 discloses a technique for preventing shortening of the lifetime of elements caused by a temperature rise depending on the flow of current, based on images such as i...
