Abstract

The invention relates to terminal equipment and a display control method and device, and belongs to the technical field of display. According to the embodiment of the invention, a control circuit controls at least one of the display parameters of an OLED display panel and the light emitting frequency of a proximity sensor when the proximity sensor emits infrared light so that the first brightnessdifference between an irradiation area irradiated by infrared light of the OLED display panel and a non-irradiation area located around the irradiation area is smaller than or equal to a preset value,wherein the preset value is smaller than a second brightness difference, the second brightness difference is the brightness difference between the irradiation area irradiated by the infrared light and the non-irradiation area when the irradiation area and the non-irradiation area are driven by the same data voltage, and the data voltage of the non-irradiation area corresponding to the first brightness difference is the same as the data voltage of the non-irradiation area corresponding to the second brightness difference. Therefore, the display difference between the irradiation area and the non-irradiation area is reduced, and the display effect is improved.

Description

technical field [0001] The present disclosure relates to the field of display technologies, and in particular, to a terminal device, a method and device for display control, and a computer-readable storage medium. Background technique [0002] The full screen has become a mainstream trend in the development of mobile terminal devices. In order to increase the screen-to-body ratio, optical sensing devices such as distance sensors are usually arranged under the organic light emitting diode (Organic Light Emitting Diode, OLED) display panel. The distance sensor judges the distance by emitting infrared light and receiving infrared light reflected by an illuminated object, such as a user's hand and / or face. Due to the large energy of the infrared light, in the process of passing through the OLED display panel, it will excite the illuminated pixels of the OLED display panel to emit light, thereby generating bright spots on the OLED display panel and affecting the display effect of...
