Abstract: Disclosed herein are liquid-crystal display (LCD) touch screens that integrate the touch sensing elements with the display circuitry. The integration may take a variety of forms. Touch sensing elements can be completely implemented within the LCD stackup but outside the not between the color filter plate and the array plate. Alternatively, some touch sensing elements can be between the color filter and array plates with other touch sensing elements not between the plates. In another alternative, all touch sensing elements can be between the color filter and array plates. The latter alternative can include both conventional and in-plane-switching (IPS) LCDs. In some forms, one or more display structures can also have a touch sensing function. Techniques for manufacturing and operating such displays, as well as various devices embodying such displays are also disclosed.

Abstract: Un método y aparato de cortraluz de LEDs para sistemas de pantalla proporciona una pluralidad de diodos emisores de luz que tienen diferentes colores de punto blanco. Por lo menos dos de los diodos emisores de luz que tienen diferentes colores de punto blanco se seleccionan para producir una luz de un color de punto blanco predeterminado cuando las salidas de luz de los diodos emisores de luz seleccionados se mezclan. Los diodos emisores de luz seleccionados se montan en un panel de pantalla en un orden predeterminado en posiciones distribuidas espacialmente para mezclar sus salidas de luz, para producir la luz del color de punto blanco predeterminado, con el fin de iluminar el panel de pantalla con luz del color de punto blanco predeterminado.

Abstract: An integrated liquid-crystal display (LCD) touch screen 100 is provided in which touch-sensing elements can be completely implemented within the LCD stack. The LCD stack comprises a first and a second polarizer; a first and a second substrate disposed between the polarizers, display control circuitry formed on the first substrate, a liquid crystal layer disposed between the substrates and at least one touch sensing element. At least one of the touch-sensing elements is disposed between the polarizers but not between the substrates. In some embodiments all of the touch sensing elements can be disposed outside the substrates. The touch sensing elements may be formed on the second substrate. The touch sensor may comprise a first layer with a plurality of drive electrodes 105a and a second layer with a plurality of sense electrodes 105b, preferably formed of indium-tin oxide (ITO) and separated by a dielectric layer. Alternative the touch-sensing elements may comprise active circuitry, such as thin film transistors (TFTs). The touch sensing element may employ a mutual capacitance or self capacitance touch-sensing arrangement. Alternative examples are also provided in which all touch sensing elements are disposed between the substrates. In some of these examples, one or more display control circuit elements can also have a touch sensing function. The substrates typically comprise a color filter plate and an array plate. Techniques for manufacturing and operating such displays, as well as various devices embodying such displays are also disclosed.

Abstract: Abstract of the Disclosure An electronic device may include a display having an array of display pixels and having display control circuitry that controls the operation of the display. The display control circuitry may operate the display in 5 different modes. In a paper mode, display control circuitry may use stored spectral reflectance data to adjust display colors such that the colors appear as they would on a printed sheet of paper. In a low light mode when the ambient light level is below a threshold, the light emitted 10 from the display may be adjusted to mimic the appearance of an incandescent light source. In a bright light mode when the ambient light level exceeds a threshold, the light emitted from the display may be adjusted to maximize readability in bright light. The target white point of the 15 display may be adjusted based on which mode the display is operating in.

Abstract: Systems, methods, and devices are provided for maintaining a target white point on a light emitting diode (LED) based backlight. In one embodiment, the backlight may include two or more groups of LEDs, each driven at a respective driving strength. Each group may include LEDs of a different chromaticity, and the respective driving strengths may be adjusted, for example, by varying the duty cycles, to maintain the target white point. To ensure that the white point may be maintained over an operational temperature range of the backlight, the LEDs may be selected so that the chromaticities of each group of LEDs are separated by at least a minimum chromaticity difference. Further, the LEDs may be selected so that at the equilibrium temperature of the backlight, the LEDs may produce the target white point when driven at substantially equal driving strengths.

Abstract: Systems, methods, and devices are provided for maintaining a target white point on a light emitting diode (LED) based backlight 32. In one embodiment, the backlight 32 may include two or more groups of LEDs N3, N8, each driven independently at a respective driving strength. Each group may include LEDs N3, N8 of a different chromaticity, and the respective driving strengths 88, 90 may be adjusted, for example, by varying the duty cycles, to compensate for age effects or temperature changes to maintain the target white point. To ensure that the white point may be maintained over an operational temperature range of the backlight 32, the LEDs N3, N8 may be selected so that the chromaticities of each group of LEDs N3, N8 are separated by at least a minimum chromaticity difference. Further, the LEDs N3, N8 may be selected so that at the equilibrium temperature of the backlight 32, the LEDs N3, N8 may produce the target white point when driven at substantially equal driving strengths.
