INKJET HEAD DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18034782 titled 'INKJET HEAD DEVICE
Simplified Explanation
The abstract describes an inkjet head device that sprays light emitting devices onto a substrate in droplets. The device includes a body with light emitting devices, a nozzle for spraying the devices, and a guide part to align the devices in a line.
- The inkjet head device sprays light emitting devices onto a substrate in droplets.
- The device includes a body with light emitting devices and a nozzle for spraying the devices.
- A guide part is used to align the light emitting devices in a line before they are sprayed.
- This ensures that the same or similar number of light emitting devices are included in each droplet.
- The uniform distribution of light emitting elements in each sub-pixel results in uniform luminance.
Potential Applications
- Display technology: This technology can be used in the manufacturing of displays, such as OLED or LED screens, to ensure uniform luminance across sub-pixels.
- Lighting: The inkjet head device can be used to create lighting solutions with consistent brightness and color accuracy.
Problems Solved
- Uneven luminance: By aligning the light emitting devices in a line and spraying them in droplets, the patent solves the problem of uneven luminance in displays or lighting solutions.
- Inconsistent color accuracy: The uniform distribution of light emitting elements in each sub-pixel helps to maintain consistent color accuracy.
Benefits
- Uniform luminance: The patent ensures that each sub-pixel has the same or similar number of light emitting devices, resulting in uniform luminance across a display or lighting solution.
- Improved color accuracy: By aligning and distributing the light emitting elements evenly, the patent helps to maintain consistent color accuracy in displays or lighting solutions.
Original Abstract Submitted
An inkjet head device comprises a body comprising light emitting devices, a nozzle installed on a lower side of the body to spray the light emitting devices onto the substrate in units of droplets, and a first guide part disposed in the body to guide the light emitting devices to the nozzle in a line. Since the light emitting devices arranged in a line by the first guide part are dropped on the substrate in units of a predetermined amount of droplets, the number of light emitting devices included in each droplet may be the same or similar. Thus, since the same or similar number of light-emitting elements are disposed or aligned in each sub-pixel, the luminance in each sub-pixel obtained by the light-emitting elements can be uniform.
