[0069] Overall structure of display device with input function

[0070] figure 1 An example of the overall structure of the display device (display camera device) with an input function of the first embodiment of the present invention is shown. This display device includes an I / O display panel 20 , a backlight 15 , a display drive circuit 12 , a light reception drive circuit (light detection drive circuit) 13 , an image processing unit 14 , and an application execution unit 11 .

[0071] The I / O display panel 20 is, for example, a liquid crystal display (Liquid Crystal Display; LCD) panel. I / O display panel 20 includes such as image 3 A plurality of display pixels 31RGB arranged in a matrix are shown (to be described later), and have a function (display function) of displaying predetermined images such as graphics and characters based on image data while performing a line-sequential operation. The I / O display panel 20 also includes image 3 Shown (to be described later) a...

[0165] The overall structure of the radiation imaging device

[0166] In the second embodiment, a configuration example in which the present invention is applied to a radiation imaging device will be described. Figure 24 The system configuration of the photoelectric converter 102 included in the radiation imaging device 101 of the present embodiment is shown. Such as Figure 25 As shown, the radiation imaging device 101 is provided with a wavelength converter 140 on the photoelectric converter 102 . The radiation imaging device 101 reads information from radiation by converting the wavelength of radiation represented by α-rays, β-rays, γ-rays, and X-rays with the wavelength converter 140 .

[0167] The wavelength converter 140 converts the wavelength of the above radiation into a wavelength in the sensitive range of the photoelectric converter 102 . The wavelength converter 140 is a phosphor (such as a scintillator) for converting radiation such as X-rays into light having...

Abstract

The invention provides a sensor device, a driving method, a display device, an electronic unit and an image pickup device. The sensor device includes sensor elements two-dimensionally arranged and a sensor driving section driving the sensor elements. Each of the sensor elements includes a photoelectric conversion element generating electric charge according to an amount of received light, a charge storage section connected to one end of the photoelectric conversion element and storing electric charge generated by the photoelectric conversion element, a readout section reading either a voltage value resulted from the electric charge in the charge storage section or the stored electric charge, to output the read voltage value or the read electric charge and a reset section resetting the electric charge in the charge storage section through supplying a predetermined reset voltage to the charge storage section. The sensor driving section controls the reset section so that the predetermined reset voltage is continuously or intermittently supplied to the charge storage section over a period exceeding one horizontal scan period.
