An instrument-based gradient ring display method, medium, instrument and device

Abstract

The invention relates to a gradient circular ring display method based on an instrument, a medium, the instrument and a device. The method comprises the following steps: acquiring a to-be-processed circular ring and a preset starting pixel point of the to-be-processed circular ring, and computing a deflection angle, in relative to the preset starting pixel point, of the to-be-processed pixel point; computing target transparency of the to-be-processed pixel point according to the deflection angle; adjusting the transparency of the to-be-processed pixel point as the target transparency, therebyacquiring and displaying the target gradient circular ring. A computer program is stored on the medium to execute the above method steps; the instrument comprises the storage medium and a processor; the processor realizes the above method steps when executing the computer program on the storage medium. Through a certain targeted algorithms, the gradient circular ring is displayed in the instrument, a demand on a liquid crystal instrument display effect by a user is satisfied, and the vision experience of the user is improved; the use resource is less, the system overhead is greatly reduced, and the smooth running of the entire software can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of vehicle instruments, in particular to an instrument-based gradual circle display method, medium, instrument and device. Background technique [0002] At present, the on-board instruments in the automotive industry have entered the state of full LCD products. As a very important part of the whole system of the car, the car instrument is one of the important directions to improve the overall performance of the car, and the requirements of car manufacturers and users are getting higher and higher. The full LCD instrument uses a liquid crystal display (Liquid Crystal Display, LCD) to replace the traditional stepping motor pointer instrument panel, which has rich display phenomena, beautiful and gorgeous interface, high display sensitivity and precision. New liquid crystal instrument products have higher and higher requirements for graphical interfaces, and users have put forward more requirements for graphic...

Problems solved by technology

[0008] 1. The first technical solution: it does not meet the needs of users and reduces the realization conditions;

[0009] 2. The second technical solution: consumes a large amount of system resources of the central processing unit (Central Processing Unit, CPU) and graphics processing unit (Graphics Processing Unit, GPU), resulting in running freezes and affecting the display effect of other instruments;

[0010] 3. The third technical solution: When the ring changes with the value, the effect is not realistic enough, the intuitive feeling is poor, and it needs to cooperate with other image resources to block, which increases the consumption of system resources and will bring the overall software performance degradation
