Abstract: In an array substrate, a control electrode of a driving transistor, a second electrode of a compensation transistor and a second electrode of a first reset transistor are electrically connected to a first conductive connection portion, and a first electrode of the driving transistor and a second electrode of a data writing transistor are electrically connected to a second conductive connection portion. An orthographic projection of a first conductive portion of the first conductive connection portion overlaps with an orthographic projection of a first scan signal line, and overlaps with an orthographic projection of a second scan signal line. A first shielding layer includes a first shielding pattern; in a thickness direction of the substrate, the first shielding pattern is located between the first scan signal line and the first conductive portion, and/or the first shielding pattern is located between the second scan signal line and the first conductive portion.

Abstract: An array substrate includes a substrate and pixel circuits disposed on the first substrate. A pixel circuit includes a first light-emitting control transistor and a second light-emitting control transistor. The array substrate further includes a first light-emitting control signal line and a second light-emitting control signal line. The first light-emmitting control signal line is electrically connected to a gate of the first light-emitting control transistor. The second light-emitting control signal line is electrically connected to a gate of the second light-emitting control transistor. The array substrate further includes conductive layers. The first light-emitting control signal line and the second light-emitting control signal line are electrically insulated. The first light-emitting control signal line and the second light-emitting control signed line are located in different conductive layers.

Abstract: The present invention discloses a domain wall straightening method of a periodically poled ferroelectric crystal. In the present invention, by testing a piezoelectric coefficient of a poled sample, the poling condition of the sample can be judged nondestructively, and the region of uniform poling can be screened out. At the same time, according to the calculation result of a duty cycle, the continuation or stop of poling, and the re-poling after single domain can be judged. The flatness of the domain wall is judged through the change quantity of the piezoelectric coefficient, and the size and the duration of the poling voltage are adjusted in time, to accurate control the poling process, so as to obtain high-quality periodically poled crystals.

Abstract: The present invention belongs to the field of forest ecological culture and discloses a method for improving the survival rate of a directly-planted seedling and a transplanting seedling of a haloxylon plant in desert or semi-desert environment. In desert and semi-desert areas meeting a certain condition, the base part of the stem of the directly-planted seedling or the transplanting seedling of the haloxylon plant is protected by using a cylindrical pipe or hollow bullet-shaped pipe of a certain specification from damage or even death caused by stress factors such as a ground surface layer at high temperature. Through the present invention, the survival rate of a directly-planted seedling and a transplanting seedling of the haloxylon plant under extremely stress conditions in the desert and semi-desert areas can be obviously improved, and the average improvement rate is over 50%, the quick growth and development of individuals are promoted and the annual mass growth is increased.
