Description

Large-size ultrahigh-resolution black-and-white liquid crystal spliced screen for 3D printing

Technical Field

The utility model relates to a 3D prints the field, in particular to liquid crystal concatenation screen for 3D prints.

Background

At present, common liquid crystal splicing screen mainly used is outdoor or indoor, and this liquid crystal splicing screen includes the vertical sub-screen of arranging of polylith, in order to alleviate mutual atress between the sub-screen, avoids the sub-screen of lower part to be fractured, and each sub-screen can remain respectively original frame usually. For example, chinese utility model patent publication No. CN201616252U describes a tiled flat panel display, which includes a plurality of display units, each of which has a display module and a frame surrounding the display module.

Furthermore, in order to further enhance the connection strength and signal transmission between the sub-screens, a connection structure is generally disposed between the sub-screens. For example, in chinese utility model publication No. CN203259745U, a spliced screen is described, in which at least one connector is provided between sub-screens to omit a multi-screen controller and a signal adapter board.

However, in the field of photocuring 3D printing, the liquid crystal display screen used is a monochrome liquid crystal display screen, not a color liquid crystal display screen. In recent years, as the size of printed products increases, the size of monochrome liquid crystal displays is also required to increase.

However, the current monochrome lcds have only high resolution and small size, and do not exceed 13.3 inches in size and have ultrahigh resolution greater than 5760 × 3240 (aspect ratio 16: 9). Most 3D printing manufacturers can only adopt a large-size and low-resolution color liquid crystal display screen as a substitute, but the large-size and low-resolution color liquid crystal display screen meets the 3D printing size, but cannot meet the 3D printing precision, the printed product has poor appearance effect, and the color liquid crystal display screen has high energy consumption and low efficiency. The reason is that the 3D printing industry is in a development stage, and the demand of the liquid crystal display screen is not large for the black-and-white monochromatic liquid crystal display screen with large size and ultrahigh resolution, so manufacturers of the liquid crystal display screen or the driving circuit are limited by research and development costs, are reluctant to develop the black-and-white monochromatic liquid crystal display screen or the driving board card with large size and ultrahigh resolution independently, and cause a state of unequal actual requirements and production conditions.

Subsequently, the above-mentioned idea of mainly using the liquid crystal splicing screen outdoors or indoors is also applied to the field of photocuring 3D printing. For example, chinese patent application publication No. CN109968662A describes a light source device and a 3D printing system. In the 3D printing system, the angle between two adjacent sub-screens is adjusted, so that the frames of the sub-screens are prevented from blocking light to form blind areas. However, this approach has the disadvantage that fine adjustment of the angle between the multiple sub-screens is very time consuming, detrimental to the production of the 3D printing system, and the error is still in the millimeter level.

Based on the above, it is an urgent need to solve the problem of providing a large-size ultra-high resolution black and white liquid crystal splicing screen for 3D printing.
