Patent number: 9159291Abstract: The liquid crystal display device performs display by changing the number of gray scales depending on external light intensity, and switches the display mode in accordance with a content to be displayed on a display. By controlling a display mode-specific video signal generation circuit depending on external light intensity, an inputted video signal is outputted as an analog value, is outputted with a digital value of a binary, or is outputted with a multiple digital value. As a result, display gradation of a pixel changes timely. Accordingly, a clear image can be displayed. For example, a display device which secures visibility can be obtained in a wide range from under fluorescent light in a dark place or indoor to under outdoor sunlight.Type: GrantFiled: May 9, 2006Date of Patent: October 13, 2015Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Shunpei Yamazaki, Jun Koyama, Yoshifumi Tanada, Mitsuaki Osame, Hajime Kimura, Ryota Fukumoto, Hiromi Yanai

Patent number: 8599124Abstract: It is an object of the present invention to provide a display device in which images can be seen under a dark place to intense external light. In the display device, display is performed by changing the gray scale number depending on external light intensity, and display modes can be switched depending on contents displayed on the screen. An analog mode and a digital mode are switched depending on external light intensity. In an analog digital switching circuit, when a video signal is an analog value, a signal is outputted to a pixel array without any change and, when the video signal is a digital value, the signal is outputted to a circuit that performs a digital operation such as a latch circuit. Consequently, display gray scales of a pixel are changed appropriately. Accordingly, a clear image can be displayed. For example, it is possible to ensure visibility in a wide range of a dark place or under indoor florescent light to outdoor sun light.Type: GrantFiled: November 24, 2009Date of Patent: December 3, 2013Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Shunpei Yamazaki, Jun Koyama, Yoshifumi Tanada, Mitsuaki Osame, Hajime Kimura, Ryota Fukumoto, Hiromi Yanai

Publication number: 20120056862Abstract: To provide a display device whose display can be recognized even in dark places or under the strong outside light. The display device performs display by controlling the number of gray scales in accordance with the intensity of outside light, which means a display mode can be switched in accordance with the data to be displayed on the display screen. A video signal generation circuit is controlled in each display mode in such a manner that it directly outputs an input video signal with an analog value, outputs a signal with a binary digital value, or outputs a signal with a multivalued digital value. As a result, gray scales displayed in pixels are timely changed. Accordingly, clear images can be displayed while maintaining high visibility in various environments, in the wide range from, for example, dark places or indoors (e.g., under a fluorescent lighting) to outdoors (e.g., under the sunlight).Type: ApplicationFiled: November 14, 2011Publication date: March 8, 2012Applicant: SEMICONDUCTOR ENERGY LABORATORY CO., LTD.Inventors: Shunpei Yamazaki, Jun Koyama, Yoshifumi Tanada, Mitsuaki Osame, Hajime Kimura, Ryota Fukumoto, Hiromi Yanai

Patent number: 7724247Abstract: The object of the invention is to provide a display device of which the display is visible in a dark place or under strong external light. The present invention is a display device which performs display, changing the grayscale number corresponding to the external light strength, and a display device which can switch the display mode corresponding to contents displayed on the screen. The display contents include a text display mode displaying mainly characters and symbols, a picture display mode displaying images with a small number of colors such as a comic, a video mode displaying natural images with a large number of colors such as a photograph and a moving image, and the like. By switching the grayscale number arbitrarily according to these display modes, visibility can be ensured in a wide range from a dark place or under an indoor fluorescent light to under outdoor sunlight.Type: GrantFiled: May 1, 2006Date of Patent: May 25, 2010Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Shunpei Yamazaki, Jun Koyama, Mitsuaki Osame, Yoshifumi Tanada, Ryota Fukumoto, Hiromi Yanai

Patent number: 7324123Abstract: Outside light is received using a light sensor, and in accordance with the outside light intensity, each of a first display mode which expresses multiple gray scales and a second display-y mode which expresses a gray scale smaller in number than that in the first display mode is switched and used. The switching is controlled by a display controller based on data of the outside light intensity. Accordingly, the visibility can be ensured in a wide range of situations, from under a fluorescent lamp in a dark place or inside, to under sunlight outside. In the second display mode, frequencies of a start pulse and a clock pulse to be inputted to a source signal line driver circuit are reduced and a driving voltage is decreased by the display controller; accordingly, a frame period can be longer than that in the first display mode and power consumption can be reduced.Type: GrantFiled: May 19, 2006Date of Patent: January 29, 2008Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Shunpei Yamazaki, Jun Koyama, Yoshifumi Tanada, Mitsuaki Osame, Hajime Kimura, Ryota Fukumoto, Hiromi Yanai, Hideaki Shishido

Patent number: 7323924Abstract: A low-power consumption level shifter circuit is provided by preventing a through current which is generated when a level of a signal is changed. In order to prevent a through current which flows when a level of a signal of the input is changed, the p-channel TFTs are controlled so that the p-channel TFTs and the n-channel TFT or the p-channel TFTs and the n-channel TFT are not turned on at once. A high level signal is inputted to the gate of the n-channel TFT, and at the moment when the n-channel TFT is turned on, the p-channel TFT is turned off. Similarly, at the moment when the n-channel TFT is turned on, the p-channel TFT is turned off. The p-channel TFTs and the n-channel TFT, or the p-channel TFTs and the n-channel TFT are not turned on at once, thereby a path in which the through current flows is cut off.Type: GrantFiled: April 18, 2006Date of Patent: January 29, 2008Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Mitsuaki Osame, Hiromi Yanai
