Abstract: A method for testing photosensitivity of an electronic display module, such as a liquid crystal display module, is provided. In one embodiment, a method includes exposing a display module to light at a first intensity and measuring an amount of light transmitted through the display module. The method may also include exposing the display module to light at a second intensity and measuring an amount of that light transmitted through the display module. The measured amounts may then be compared to determine an optical property, such as photosensitivity, of the display panel. Various other methods, systems, and manufactures are also disclosed.

Abstract: Processes for fabricating compact touch sensors for touch sensitive devices are disclosed. A process can include providing a touch sensor structure having a substrate, a first layer disposed on the substrate, and a second layer disposed on the first layer. The second layer can have an ablation fluence value that is lower than an ablation fluence value of the first layer. The process can include patterning the second layer with a laser emitting energy having a fluence value greater than or equal to the ablation fluence value of the second layer and less than the ablation fluence value of the first layer. The process can further include etching at least a portion of the first layer that was exposed during the patterning of the second layer.

Abstract: Embodiments of the present invention provide for a FFS TFT LCD with a high refresh rate without limiting the aperture of individual pixels. More specifically, embodiments of the invention provide for the use of common bus lines to reduce the effective resistance of the common electrode and to therefore allow for higher refresh rates of the display. Furthermore, the common bus lines can be positioned in such a manner so that they do not further reduce the aperture of the display. More specifically, the common bus lines can be positioned above or below existing elements of the display that are already opaque. Thus, adding the common bus lines need not reduce the aperture. The above can be achieved by, for example, placing the common bus lines above or below existing non-transparent lines, such as gate lines or data lines.
Abstract translation: 本发明的实施例提供了一种具有高刷新率的FFS TFT LCD，而不限制各个像素的孔径。 更具体地，本发明的实施例提供了使用公共总线线路来降低公共电极的有效电阻并因此允许显示器的更高刷新率。 此外，公共总线线路可以以这样的方式定位，使得它们不会进一步减小显示器的孔径。 更具体地，公共总线可以位于显示器的已经不透明的现有元件的上方或下方。 因此，添加公共总线不需要减小孔径。 上述可以通过例如将公共总线放置在现有的不透明线路之上或之下，例如栅极线或数据线来实现。

Abstract: Display layers and touch sensor layers may be overlapped by enclosure walls in an electronic device. The electronic device may have a front wall and opposing rear wall and curved sidewalls. The front wall and the curved sidewalls may be formed from a glass layer or other transparent member. A touch sensor layer and display layer may extend under the glass layer with curved sidewalls. A touch sensor layer may also extend under the opposing rear wall. A foldable electronic device may have a flexible transparent wall portion that joins planar transparent walls. Components may be interposed between the transparent planar walls and opaque walls. Display and touch layers may be overlapped by the transparent walls and the transparent flexible wall portion. Touch sensor structures may also be overlapped by the opaque walls.

Abstract: A display may have an array of pixels. Display driver circuitry may supply data and control signals to the pixels. Each pixel may have seven transistors, a capacitor, and a light-emitting diode such as an organic light-emitting diode. The seven transistors may receive control signals using horizontal control lines. Each pixel may have first and second emission enable transistors that are coupled in series with a drive transistor and the light-emitting diode of that pixel. The first and second emission enable transistors may be coupled to a common control line or may be separately controlled so that on-bias stress can be effectively applied to the drive transistor. The display driver circuitry may have gate driver circuits that provide different gate line signals to different rows of pixels within the display. Different rows may also have different gate driver strengths and different supplemental gate line loading structures.

Abstract: Electrical shield line systems are provided for openings in common electrodes near data lines of display and touch screens. Some displays, including touch screens, can include multiple common electrodes (Vcom) that can have openings between individual Vcoms. Some display screens can have an open slit between two adjacent edges of Vcom. Openings in Vcom can allow an electric field to extend from a data line through the Vcom layer. A shield can be disposed over the Vcom opening to help reduce or eliminate an electric field from affecting a pixel material, such as liquid crystal. The shield can be connected to a potential such that electric field is generated substantially between the shield and the data line to reduce or eliminate electric fields reaching the liquid crystal.

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: An electronic device with a force sensing device is disclosed. The electronic device comprises a user input surface defining an exterior surface of the electronic device, a first capacitive sensing element, and a second capacitive sensing element capacitively coupled to the first capacitive sensing element. The electronic device also comprises a first spacing layer between the first and second capacitive sensing elements, and a second spacing layer between the first and second capacitive sensing elements. The first and second spacing layers have different compositions. The electronic device also comprises sensing circuitry coupled to the first and second capacitive sensing elements configured to determine an amount of applied force on the user input surface. The first spacing layer is configured to collapse if the applied force is below a force threshold, and the second spacing layer is configured to collapse if the applied force is above the force threshold.
