Integrated black equipment based on bidirectional reflection function layer compensation

Abstract

The invention relates to the technical field of display equipment, in particular to integrated black equipment based on bidirectional reflection function layer compensation. The equipment comprises a cover plate, printing ink, OCA, an upper polaroid, liquid crystal color film glass, a glass substrate and a functional film. The functional film comprises a base material 1, a double-reflection layer, a base material 2 and a pressure-sensitive adhesive, wherein the base material 1, the double-reflection layer, the base material 2 and the pressure-sensitive adhesive are sequentially attached from top to bottom; the top of the cover plate is provided with a functional area and a non-functional area, the functional film is attached to the outer side of the cover plate, the functional film with the double-reflection characteristic is added to compensate the double-reflection characteristic of the polaroid, the integrated black effect is achieved in two directions, compensation of the double-reflection characteristic is achieved through a birefringence material, in this way, the full-angle integrated black effect can be achieved, and the black screen problem of a traditional display product can be solved.

Description

technical field [0001] The invention relates to the technical field of high display devices, in particular to an integrated black device based on bidirectional reflection function layer compensation. Background technique [0002] With the acceleration of the development of automobile intelligence, vehicle-mounted displays are developing towards large-size, multi-screen, high-definition, interactive, and multi-modal. There are also higher requirements for display performance, including high contrast, low reflectivity, wide Viewing angle, high brightness, touch control and fast response, etc. In addition, the novel design of the details and structure of the vehicle display screen can also play an unexpected role in improving product competitiveness. Therefore, the "integrated black" technology that can create novel, eye-catching, beautiful and technological vehicle display effects will become one of the trends. The boundary between the ink area and the visible area cannot be...

Problems solved by technology

[0004] However, in some cases, the products with △E<2 can still see obvious color difference, or the one-piece black effect is not good. Through analysis, we found that △E in these cases has angle dependence, that is, different angles The value of △E is different. Further analysis shows that this angle dependence comes from the polarizer of the liquid crystal module. The polarizer has absorption and transmission axes, and the reflectivity in the two directions of the absorption axis and the transmission axis is different. Therefore, The laminated product will also have different reflectivity in the two directions of the absorption axis and the transmission axis, because the L* value in the ΔE model is positively correlated with the reflectance of the product, so the laminated product will have different reflectivity in the two directions of the absorption axis and the transmission axis. Different L* values ​​on

At this time, if we adjust and match the ink in one direction to achieve ΔE<2, the ΔE in the other direction may be greater than 2. Therefore, the current structural method is not comprehensive and the effect is not good. In view of this, we propose An integrated black device based on bidirectional reflection function layer compensation
