Embodiment Construction

[0026] Electronic devices may include displays. The display can be used to display images to the user. figure 1 , figure 2 , image 3 and Figure 4 An exemplary electronic device that may have a display is shown in .

[0027] figure 1 It is shown how electronic device 10 may have the shape of a laptop computer having an upper housing 12A and a lower housing 12B having components such as keyboard 16 and touchpad 18 . Device 10 may have a hinge structure 20 that allows upper housing 12A to rotate in direction 22 about an axis of rotation 24 relative to lower housing 12B. Display 14 may be mounted in upper housing 12A. Upper housing 12A, which may sometimes be referred to as a display housing or cover, can be placed in a closed position by rotating it toward lower housing 12B about axis of rotation 24 .

[0028] figure 2 It is shown how electronic device 10 may be a handheld device such as a cellular telephone, music player, gaming device, navigation unit, or other comp...

Abstract

A display may have an array of pixels arranged in rows and columns. Each pixel may have a transistor for controlling the amount of output light associated with that pixel. The transistors may be thin-film transistors having active areas, first and second source-drain terminals, and gates. Gate lines may be used to distribute gate control signals to the gates of the transistors in each row. Data lines that run perpendicular to the gate lines may be used to distribute image data along columns of pixels. The gate lines may be connected to gate line extensions that run parallel to the data lines. The data lines may each overlap a respective one of the gate line extensions. Vias may be used to connect the gate line extensions to the gate lines. The gate line extensions may all have the same length.

Description

[0001] This patent application claims priority to US Patent Application No. 14 / 504,215, filed October 1, 2015, which is incorporated herein by reference in its entirety. Background technique [0002] The present invention relates generally to electronic devices, and more particularly to electronic devices having displays. [0003] Electronic devices often include displays. For example, cellular telephones and portable computers often include displays for presenting information to users. [0004] A liquid crystal display includes a layer of liquid crystal material. A pixel in a liquid crystal display contains thin film transistors and electrodes for applying an electric field to the liquid crystal material. The strength of the electric field in the pixel controls the polarization state of the liquid crystal material and thereby adjusts the brightness of the pixel. [0005] Substrate layers such as color filter layers and thin film transistor layers are used in liquid crystal...
