Embodiment Construction

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0043] The inventor found in the research that the current reasons for the flickering of the LCD screen at low temperatures include: because the entire temperature axis uses a set of frame rates, the frame rate used is higher than the normal display of the LCD screen at low temperatures The required frame rate, which in turn causes the LCD screen to appear flickering at low temperatures.

Abstract

The invention provides a frame frequency control method and device of a liquid crystal screen and a liquid crystal screen display system. The method comprises the steps that whether the temperature of the liquid crystal screen changes from one temperature range to another temperature range in a plurality of preset temperature ranges or not is detected; the plurality of temperature ranges are determined by a plurality of preset temperature nodes; under the condition that the temperature of the liquid crystal screen changes from one temperature range to another temperature range in a plurality of preset temperature ranges, a frame frequency corresponding to the temperature range to which the temperature belongs is determined according to a preset relationship between the plurality of temperature ranges and the frame frequency, and obtaining a target frame frequency, wherein different temperature ranges in the corresponding relation correspond to different frame frequencies; and the frame frequency of the integrated circuit of the liquid crystal screen is controlled to be adjusted to the target frame frequency. The problem of splash screen of the liquid crystal screen at low temperature can be solved.

Description

technical field [0001] The present application relates to the field of optoelectronic display, in particular to a method and device for controlling the frame rate of a liquid crystal screen, and a display system of a liquid crystal screen. Background technique [0002] Liquid crystal screens (for example, FSTN screens) are widely used in devices such as walkie-talkies due to their low cost, low power consumption, and outdoor visible features. [0003] However, in a low temperature environment, the FSTN LCD screen will have a flickering problem, which will affect the display effect and customer experience. In serious cases, it will also affect the real-time performance of information acquisition, resulting in missing important information. Contents of the invention [0004] The present application provides a frame rate control method and device of a liquid crystal screen, and a display system of a liquid crystal screen, aiming at solving the problem of flickering of the li...
