An object of the present invention is to provide a character display system that allows a verification operator to adjust a work screen for verification to a display method with ease of work for oneself. The problem is solved by providing a display format determining device. In the presence of adjusted display information obtained by adjustment such that the characters of character image data and the characters of recognized character data with the characters being displayed to be aligned with each other are arranged to facilitate comparison between the characters by a verification operator, the display format determining device decides that the recognized character data information is displayed based on the adjusted display information, and in the absence of the adjusted display information, the display format determining device decides that the recognized character data information is displayed based on initial display information determined in advance according to a verification target.

When a plurality of amplification devices each including a display unit are used in combination, deterioration in visibility of displayed information is prevented. An amplifier unit includes a connection mode specifying unit that detects another amplifier unit including another display unit which is disposed to form one display area along with the display unit and a display control unit that displays information in the display area formed by a plurality of display units.

A display device includes: a display that displays an image based on image data; a backlight device that irradiates the display with light; an image determiner that determines, based on the image data, whether the image includes a target image having a contrast higher than a reference contrast; and a luminance value setter that sets each luminance value of the image based on the image data, wherein when the image determiner determines that the image includes the target image, the luminance value setter changes the luminance value set for at least one of two or more areas in the target image to reduce a difference between the luminance values of the two or more areas in the target image set based on the image data.

A Charlieplexing IO-driven OLED segment, comprising a plurality of OLED segments and an MCU chip for supplying power to each of the OLED segments. The MCU chip has a plurality of I/O pins that can change the output electrodes at a preset time interval. Each I/O pin is electrically connected to the positive electrodes of the plurality of OLED segments and the negative electrodes of the plurality of OLED segments. The positive electrode and the negative electrode of each OLED segment are electrically connected to two of the I/O pins of the MCU chip, respectively. The MCU chip, by controlling the change of output electrodes of the I/O pins, enables the preset OLED segments to match each other with fast flashing to produce a visual effect of coherent illumination. The preset OLED segment does not need to remain lit, reducing overall energy consumption.

A display device includes: a display that displays an image based on image data; a backlight device that irradiates the display with light; an image determiner that determines, based on the image data, whether the image includes a target image having a contrast higher than a reference contrast; and a luminance value setter that sets each luminance value of the image based on the image data, wherein when the image determiner determines that the image includes the target image, the luminance value setter changes the luminance value set for at least one of two or more areas in the target image to reduce a difference between the luminance values of the two or more areas in the target image set based on the image data.
