Publication number: 20100230610Abstract: An integrated device for detecting emissions from a sample (70) involves forming an array of photo detectors (20) for detecting the emissions and forming an array of sites for receiving the sample such that edges of the sites are defined by edges of the photo detectors. A side wall of a site using a diode can provide a side wall suitable for ink-jet printing samples such as biomolecules with no extra mask steps. This helps enable the sample and the photo detector to be mutually aligned more easily or more cost effectively than conventional devices where the site for receiving the sample is formed separately from the photo detector. The detection can be in any direction, such as lateral or vertical detection. Lateral optical detection with a shielded photodiode means only light emanating from one pixel/spot is detected. A light source (200) to stimulate emissions can be integrated.Type: ApplicationFiled: March 20, 2007Publication date: September 16, 2010Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Pieter Jan Van Der Zaag, Nigel David Young, Hendrik Roelof Stapert

Publication number: 20100187426Abstract: The monitoring of UV radiation has received increased attention recently due to the hazards of accelerated skin ageing and even cancer following excessive exposure. Personalized monitoring gives a more accurate reading than crude weather forecasts of the ‘UV index’. This invention answers both these needs in a personal UV monitor that is incorporated into an existing display. Minimal processing changes are made to an existing display in order to achieve this added functionality, which is therefore achieved at little additional cost.Type: ApplicationFiled: December 22, 2009Publication date: July 29, 2010Applicant: TPO Displays Corp.Inventors: Nigel David Young, Peter Fairley

Publication number: 20100053045Abstract: An active matrix display device comprises an array of display pixels, each pixel comprising: a current-driven light emitting display element (2); a drive transistor (22) for driving a current through the display element; a storage capacitor (24) for storing a voltage to be used for addressing the drive transistor; and an addressing transistor (16) for coupling data from a data line (6) to the pixel during pixel addressing. The addressing transistor (16) comprises a phototransistor, and the data line (6) is used for external monitoring of the phototransistor. This device design uses a pixel-addressing transistor (16) as the optical feedback element. This addressing transistor is a fundamental requirement of an active matrix-addressing scheme, and its use as a feedback element can therefore avoid any addition pixel complexity to implement an optical feedback function.Type: ApplicationFiled: November 21, 2007Publication date: March 4, 2010Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: David Andrew Fish, Nigel David Young, Hugo Johan Cornelissen, Steven Charles Deane

Publication number: 20090250630Abstract: A photodiode (200), for instance a PN or a PIN photodiode, is disclosed. The photodiode receives incident radiation having first and second spectral distributions, where the first spectral distribution is spectrally shifted from the second spectral distribution. The photodiode has a first semiconductor layer (211) capable of absorbing incident radiation (231) having a first spectral distribution without generating a photocurrent, while simultaneously transmitting incident radiation having a second spectral distribution to the intrinsic layer (212) for generating a photocurrent (213). The photodiode may be used in connection with detecting the presence of target molecules that has been labeled with labeling agents, such as fluorophores or quantum dots. The labeling agents are characterized by the Stokes shift and, therefore, they emit fluorescent radiation having the second spectral distribution that is spectrally shifted from the illumination radiation having the first spectral distribution.Type: ApplicationFiled: July 5, 2007Publication date: October 8, 2009Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Pieter Jan Van Der Zaag, Ian French, Nigel David Young

Patent number: 7208760Abstract: Physical barriers (210) are present between neighbouring pixels (200) on a circuit substrate (100) of an active-matrix electroluminescent display device, particularly with LEDs (25) of organic semi conductor materials. The invention forms these barriers (210) with metal or other electrically-conductive material (240), that is insulated (40) from the LEDs but connected to the circuitry within the substrate (100). This conductive barrier material (240) backs-up or replaces at least a part of the drive supply line (140,240) to which the LEDs are connected by a drive element T1. This transfers the problem of line resistance and associated voltage drop from within the circuit substrate (100), where it is severely constrained, to the much freer environment of the pixel barriers (210) on the substrate (100) where the conductive barrier material (240) can provide much lower resistance. Very large displays can be made with low voltage drops along this composite drive supply line (140,240).Type: GrantFiled: March 19, 2003Date of Patent: April 24, 2007Assignee: Koninklijke Philips Electronics N.V.Inventors: Jason Roderick Hector, Nigel David Young, David Andrew Fish, Mark Jonathan Childs
