The invention provides a light-emitting displayer with the light sensing function. The light-emitting displayer with the light sensing function comprises at least one light-emitting diode, at least one thin film transistor, at least one light sensing module and a connecting layer, wherein the light-emitting diode is formed on a first substrate, the thin film transistor and the light sensing module are electrically connected to and are formed on a second substrate, the connecting layer is connected with the first substrate and the second substrate, so that the light-emitting diode is electrically connected with the thin film transistor, light is emitted by the light-emitting diode, the light sensing module is located on the light-emitting path of the light-emitting diode, and the thin film transistor and the light-emitting diode are relatively staggered in position. According to the light-emitting displayer with the light sensing function, by means of the use characteristics of the light-emitting diode, the light intensity of the light-emitting diode is detected and controlled, and the problems of short service life of an organic light-emitting diode and color cast of a displayed image can be effectively solved.

Description

technical field [0001] The invention relates to a light-emitting display with light-sensing function, in particular to a light-emitting display with light-sensing function in which an oxide semiconductor is used as a light sensor in a circuit formed by direct bonding of a light-emitting diode and a thin film transistor. Background technique [0002] In recent years, flat panel displays have been widely used in TVs, product information display screens, smart phones, tablet computers, notebook computers, and AIO (All-in one) computers. Currently used flat-panel displays are mainly based on a backlight module and a backplane formed by thin-film transistors, which control the deflection of liquid crystals to form a thin-film transistor-liquid crystal display (TFT-LCD). For the next generation of power-saving, high-quality, and high-resolution flat-panel displays, in addition to shortening the pixel unit area, increasing the aperture ratio, and using low temperature polysilicon (...

AI Technical Summary

Problems solved by technology

However, the lifespan of organic light-emitting materials in organic light-emitting diodes, the complexity of manufacturing, and the yield rate make the application of active organic light-emitting diodes limited to small and medium-sized display applications.

Moreover, because the lifespan and luminous efficiency of the organic light-emitting materials of each color of the organic light-emitting diode display are different, there will be a problem of color shift in the image screen.
