A collimator for a dental X-ray imaging apparatus, including: a housing () having a first end and a second end, which oppose each other, the first end provided thereat with a light exit aperture, the second end secured to the dental X-ray imaging apparatus so as to define a light passage so that X-rays are able to travel through the light passage and exit from the light exit aperture; a securing means disposed at the second end, with which the housing () is detachably secured to a beam-limiting cone (); a visible light source () placed within the housing () and configured to be able to emit visible light; a window member disposed at the first end of the housing and configured to allow visible light and X-rays to transmit therethrough and be projected and irradiated onto an object to be imaged; a light-reflecting plate () placed in the housing () obliquely with respect to a longitudinal axis of the light passage and configured to be able to reflect visible light emitted from the visible light source () so that it is able to pass through the window member and be projected on the object to be imaged; a beam-limiting member disposed between the light-reflecting plate () and the window member and configured to disallow transmission of visible light and X-rays therethrough and hence define the light exit aperture.

Collimator for dental X-ray imaging apparatus

A visible light projection indicator for a dental x-ray imaging apparatus, including a casing (), one end of the casing () detachably affixed to a beam-limiting cone () in the dental x-ray imaging apparatus, the other end thereof provided with a light exit aperture; a visible light source () positioned in the casing () and configured to be able to emit visible light; the casing () affixed to the beam-limiting cone () so as to form a light passage so that visible light emitted from the visible light source () is able to travel along the light passage and exits from the light exit aperture. A method of using a visible light projection indicator for a dental x-ray imaging apparatus, including the steps of: affixing the visible light projection indicator to a beam-limiting cone (); activating at least one visible light source () to cause visible light to be emitted from a light exit aperture of the visible light projection indicator; according to a light field () of the visible light, adjusting a distance and an orientation of the beam-limiting cone () from and with respect to an object to be imaged so that the visible light is aligned with a center of an area () to be imaged; and performing an X-ray imaging operation.

Visible light projection indicator for dental X-ray imaging apparatus and method of using same

A disclosed example includes a plurality of display pixels; timing controller circuitry; driver circuitry on a same integrated circuit as the timing controller circuitry, the driver circuitry to drive the display pixels; and de-multiplexer circuitry to de-multiplex pixel data to send to the plurality of display pixels.

Display circuits

A display controller for a display may include a frame rate circuit to change a frame rate of the display from a first frame rate to a second frame rate, and a reference voltage circuit to adjust a reference voltage of the display from a first reference voltage corresponding to the first frame rate to a second reference voltage corresponding to the second frame rate. The display may be a thin film transistor liquid crystal display. The reference voltage may correspond to a common voltage (Vcom) for the display.

Display controller with multiple common voltages corresponding to multiple refresh rates

In some examples, a display includes a plurality of display pixels, an integrated timing controller and driver circuit to drive the display pixels, and a de-multiplexer circuit including one or more transistors coupled to the integrated timing controller and driver circuit and coupled to one or more of the plurality of display pixels.

Disclosed herein are techniques related to privacy at display devices. The techniques include an apparatus having an electroactive privacy layer of a display device. The electroactive privacy layer is configured to restrict a propagation direction of light emission associated with a display layer of the display device. The restriction of propagation is generated by micro louvers formed in the electroactive privacy layer.

Bridged micro louvers for active privacy screen

A touch sensitive active privacy screen, includes an apparatus having an electroactive privacy layer () of a display device. The electroactive privacy layer () is configured to restrict a propagation direction of light emission associated with a display layer () of the display device. The restriction of propagation is generated by micro louvers () formed in the electroactive privacy layer ().
