Texture image acquisition circuit, display panel and texture image acquisition method
A texture image acquisition circuit, a display panel and a texture image acquisition method. The texture image acquisition circuit includes a charge neutralization circuit and a first acquisition circuit, the charge neutralization circuit is electrically connected to the first acquisition circuit, the charge neutralization circuit receives a first control signal to cause a current flowing through the first acquisition circuit to be a first current, and the charge neutralization circuit is configured to receive a second control signal to cause a current flowing through the first acquisition circuit to be a second current, a direction of the second current and a direction of the first current are opposite to each other; the first acquisition circuit is configured to receive light from a texture and accumulate a first signal amount that is acquired after the light from the texture is converted, so as to acquire a first acquisition value.
