Abstract

The present disclosure relates to a terminal device, a method and an apparatus for display control, and belongs to the field of display technology. In the embodiment of the present disclosure, when the proximity sensor emits infrared light, at least one of the display parameters of the OLED display panel and the light-emitting frequency of the proximity sensor is controlled by the control circuit, so that the irradiation area of ​​the OLED display panel irradiated by infrared light The first luminance difference of the non-irradiated area around the area is less than or equal to a predetermined value; the predetermined value is smaller than the second luminance difference, and the second luminance difference is when the illuminated area and the non-irradiated area are driven by the same data voltage, the infrared light is irradiated The brightness difference between the illuminated area and the non-irradiated area, the data voltage of the non-irradiated area corresponding to the first brightness difference is the same as the data voltage of the non-irradiated area corresponding to the second brightness difference. That is, the brightness value of the illuminated area is reduced, so that the display difference between the illuminated area and the non-irradiated area becomes smaller, 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...
