Disclosed are an APR protection method and device, and a computer storage medium. A preamplifier PA of each of two optical amplifier units at two ends of a transmission line is connected to a booster amplifier BA of the other amplifier unit by an optical fiber. The method comprises: when a reception state of PA of at least one of two amplifier units is a loss of signal state and a switch chip of said amplifier unit detects a link interruption signal, activating an APR protection state of said amplifier unit which is to turn off BA output of said amplifier unit; when the switch chip of at least one of two amplifier units detects a link conduction signal, deactivating the APR protection state of the present amplifier unit to restore a state of BA of said amplifier unit to a state before the APR protection state is activated.

A display panel and a display device are provided. The display panel having a first display region includes a base, a pixel definition layer, and first spacers. At least one of the first spacers is provided with a via hole, and a first cathode suppression layer is disposed in the via hole. The first cathode suppression layer causes no cathode layer deposited in the via holes of the first spacers. In this way, the light transmittance of each of the first spacers in the first display region is increased, thereby increasing the light transmittance of the first display region.

The present application provides a display panel and a display device. The display panel includes: a cathode inhibition layer disposed on a side of the pixel definition layer and between light-emitting units, a cathode disposed on a side of a light-emitting layer away from a substrate, and a color filter layer disposed on the cathode away from the substrate, wherein a thickness of the cathode on the cathode inhibition layer is less than a thickness of the cathode on the light-emitting unit. A light shielding portion of the color filter layer includes a light-permeable aperture configured corresponding to the cathode inhibition layer, and a light transmittance of a light-permeable material in the light-permeable aperture is greater than a light transmittance of the light shielding portion.

A display panel and a display device are disclosed. The display panel includes a substrate, a cathode suppression layer, a cathode, and a polarizer. The cathode suppression layer includes a first cathode suppression portion located in a first light-transmitting area. The cathode is located in a first light-emitting area and the first light-transmitting area, and covers at least part of the first cathode suppression portion. The polarizer includes a first light-transmitting portion located in the first light-transmitting area. A projection of the first light-transmitting portion projected on the substrate is located within a boundary of a projection of the first cathode suppression portion projected on the substrate.

The present application discloses a display panel and a display device. The display panel includes pixel areas and transmitting areas in a first display area. The display panel further includes a light-emitting unit layer including light-emitting units, an auxiliary layer, a first electrode layer covering the light-emitting unit layer and at least part of the auxiliary layer, and a transparent auxiliary electrode layer at least covering part of the auxiliary layer and electrically connected to the first electrode layer. A thickness of the first electrode layer on the auxiliary layer is less than a thickness of the first electrode layer on the light-emitting unit layer.

An OLED light emitting device includes a substrate, a thin film transistor, an anode, an organic light emitting layer, a cathode, and a smoothing layer. The smoothing layer is disposed between the organic light emitting layer and the cathode. This improves transmittance of the cathode, and further improves light-emitting performance of the OLEO light emitting device.

Disclosed is a portable downloader comprising a pen-shaped housing and a circuit board provided inside of the pen-shaped housing. Provided at one end of the circuit board is a micro-universal serial bus (MUSB) port. Connected to the circuit board are a ground wire and two data wires. Each data wire is connected to a probe at the other end. Provided at the end of the pen-shaped housing corresponding to the MUSB port is a socket. Provided at the other end are two position-fixing holes. The two probes penetrate the position-fixing holes. The MUSB port connects to a computer universal serial bus (USB) port through a USB-MUSB computer extension wire. The portable downloader uses USB power supply with no need for an external power supply, and supports hot plug. The downloader uses the two probes as the C2 port, and is convenient to transmit data to C2 slave devices. The downloader is of a pen-shaped packaging, and is therefore easy to carry.

Portable downloader

An in-application upgrade method is used for optical module firmware not breaking a service. A storage area for internal programs of an optical module is divided into two areas which are respectively used for storing upgrade and application programs, and is divided into an area for backing up an interrupt vector table of a Boot program. An upper computer is in communication with the optical module. The interrupt vector table is switched, and the jump between the Boot program and the application program is achieved. The method includes extracting the contents of firmware, entering a download mode and updating the firmware. The original firmware is erased, and new firmware is written. An application mode is entered, the upper computer sending an exit command from the download mode. The upgrade program exits and a new application program is executed. The optical module operates normally without interruption.
