The invention relates to a laser induction panel, a manufacturing method thereof and a display device. The laser induction panel comprises a glass substrate, a plurality of sensing transistor units, acoating layer and a filling layer; the plurality of sensing transistor units are arranged on the upper surface of the glass substrate in an array manner; the coating layer comprises a plurality of covering units, each covering unit is arranged on the upper surface of the glass substrate and completely covers the sensing transistor unit, and a gap exists between any two adjacent covering units; the filling layer comprises a plurality of filling units, and the filling units are arranged in the gaps and alternately arranged with the covering units; and the refractive index of the coating layer is less than the refractive index of the filling layer. According to the invention, the light sensing effect on incident light of the laser pen can be improved, the technical problem of poor visual angle can be solved, and efficient laser sensing and display visual angle debugging functions are realized.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a laser sensor panel, a manufacturing method thereof, and a display device. Background technique [0002] Thin film transistor liquid crystal display (TFT-LCD) is widely used in the current flat panel display industry because of its light, thin, small and other characteristics, low power consumption, no radiation, and relatively low manufacturing cost. In order to broaden the commercial and household functions of liquid crystal displays, many functions are now integrated into the display, such as color temperature sensing, laser sensing, gas sensing, etc., which improves the applicable scenarios of liquid crystal displays. However, many integrated functions are in the new development stage, and there are still many processes and related designs that need to be improved in order to improve the performance of various integrated function LCDs. [0003] Such as figure 1 as shown, ...
