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.

Abstract: A display may have upper and lower display layers. A layer of liquid crystal material may be interposed between the upper and lower display layers. The display layers may have substrates. The display layers may include a color filter layer having an array of color filter elements on a glass substrate and a thin-film transistor layer having a layer of thin-film transistor circuitry on a glass substrate. Dielectric layers within the display layers such as dielectric layers within the thin-film transistor layer may have differing indices of refraction. Reflections and color shifts due to index of refraction discontinuities may be minimized by interposing graded index dielectric layers between adjacent layers with different indices. The graded index layers may be formed from structures with a continuously varying index of refraction or structures with a step-wise varying index of refraction.
