  • Publication number: 20240118028
    Abstract: An infrared heat source module is configured to minimize problems such as wrinkles or cracks in electrodes even if the patterns of a coated part and an uncoated part of the electrodes present in a current collector vary. The module improves a drying efficiency of the coated part of the current collector. An electrode using the infrared heat source module is manufactured by a process.

  • Patent number: 8179365
    Abstract: An electrophoretic display device has a first substrate that defines a plurality of sub-pixel areas; with shaped pixel electrodes formed in the sub-pixel areas. A second substrate is attached in facing relation to the first substrate during mass production. The second substrate has color filters of different colors (e.g., R, G, B). The areas of the color filters are less than the areas of their corresponding sub-pixel electrodes so as to thereby avoid or reduce a color mixture effect that may arise from mass production misalignment between the first and second substrates. In one class of embodiments, area consumed by the color filters is less than about 75% but more than about 45% of area consumed by respective pixel areas. Each pixel area comprises a white (W) sub-pixel area in addition to the differently colored sub-pixel areas (e.g., R, G, B).
