Embodiment Construction

[0043] Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus their detailed descriptions will be omitted.

[0044] Although relative terms such as "upper" and "lower" are used in this specification to describe the relative relationship of one component of an icon to another component, these terms are used in this specification only for convenience, for example, according to the description in the accompanying drawings directions for the example described above. It will be appreciated that if the illustrated device is turned over so...

Abstract

The invention relates to a data transmission method and device and a display device. The data transmission method comprises steps: image data are received and stored, wherein the image data comprise first data and second data, the first data are encrypted verification data and the second data are original data; the first data and the second data in the stored image data are compared; and if the second data and the first data are not consistent, the first data are used to replace the second data. Thus, the problem of partial crash of the display screen can be solved.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular, to a data transmission method and device, and a display device. Background technique [0002] With the development and progress of technology, RAM (random access memory, random access memory) is more and more widely used in various electronic products. In order to ensure the performance of RAM, RAM is usually tested, but due to the limitation of detection technology For some reasons, some faults in the RAM cannot be thoroughly detected, which will cause errors in the data transmission process. [0003] For example, the transistors in the RAM storage unit in the AMOLED (Active-matrix organic light-emitting diode) drive circuit may have failures such as instability, high or low turn-on voltage, etc., through commonly used BIST (Built-In Self-Test) or CRC (Cyclic Redundancy Check) may not be detected. However, when the RAM storage unit has the above-mentioned faults, i...
