Optical display structure

Abstract

An optical display structure comprises a substrate layer, a light source layer and an upper cover layer. The substrate layer comprises a substrate and at least one flat cable arrangement layer. The light source layer is arranged on the substrate layer to provide a light source and emit a plurality of light rays. The upper cover layer is arranged on the light source layer and seals the optical display structure. An upper light shielding layer is selectively arranged on the light source layer, so that cross-talk interference generated among the light rays emitted by the light source layer is shielded by using the upper light shielding layer. A lower light shielding layer is also selectively arranged below the substrate layer, and can be used for shielding reflected light on the back surface of the substrate. Preferably, the upper light shielding layer and the lower light shielding layer can also be arranged in the optical display structure at the same time so as to shield cross-talk interference and reflected light on the back surface of the substrate at the same time, and therefore, the effect of the structure is optimized.

Description

Technical field [0001] The present invention relates to a screen display device having a multilayer thin film stack structure, in particular, in which the black matrix is ​​used as a light blocking layer to boost its display resolution and perspective. Background technique [0002] In recent years, with the rapid development and extensive application of information technology, wireless communications and information appliances, many information products have been changed from traditional keyboards or mice to use the touch panel as input devices, and often with the display device Combination, as a common panel display device. In general, existing panel display devices have been applied to work and life, and can be used in accordance with the induction area provided to induce the finger of the human body or a writing tool similar to the touch pen. This is to achieve the purpose of touch. For example, the touch panel display device can be divided into resistive, capacitive, infrared...

Problems solved by technology

From the simulation analysis of these various stray light above, it can be clearly seen that due to the design of the multi-layer film stack structure in the light-emitting diode display device, and each layer of film has a different material refractive index and scattering Ability, leading to these various stray light caused by reflection, will affect the imaging effect of the final display image, and reduce its image resolution and perspective, which will seriously degrade the display effect of the display and the viewing quality of the user
