Answer: True.
Answer analysis: It is correct that the viewing angle of LED digital tubes is larger than that of LCD screens.
First, from the perspective of the structure and working principle of the two:
* LED digital tubes display numbers or characters through the clever layout and combination of multiple LED light-emitting diodes sealed in fixed plastic components. Since LED light-emitting diodes have the characteristics of self-luminescence and the light scattering angle is relatively large, the viewing angle of LED digital tubes is usually wider.
* LCD screens rely on the arrangement of liquid crystal molecules and the backlight source to display images. The viewing angle of LCD displays is limited by the arrangement of liquid crystal molecules and the scattering angle of the backlight source, resulting in a decrease in the viewing effect at different angles, such as reduced brightness and color distortion.
Second, from the comparison of parameters in actual applications:
* The viewing angle of LED displays (although the discussion here is about LED digital tubes, the concept of viewing angle of LED displays is similar) is usually larger, for example, it can reach 140°/140° (horizontally and vertically) or even wider. This means that viewers can clearly see the content on the display within a larger angle range.
* The viewing angle of LCD screens is relatively small, with common viewing angles ranging from 178 degrees to 160 degrees. Although this is a relatively large viewing angle range, it is still relatively small compared to LED digital tubes.
Finally, from the perspective of user experience:
* Due to its wide viewing angle, LED digital tubes allow viewers to clearly see the displayed content at different positions and angles, thereby improving user experience.
* Although LCD screens can also provide better display effects, in some occasions where a larger viewing angle is required, the viewing experience of the audience may be affected due to viewing angle limitations.
In summary, it is correct to say that the viewing angle of LED digital tubes is larger than that of LCD screens. This is mainly due to the self-luminous characteristics of LED light-emitting diodes and the wider light scattering angle.
