C, coordination of protective panel and display effect
The picture quality balance of the wall-hung advertising machine protected by 4mm tempered glass: the screen surface is covered with 4mm thick tempered glass panel, and after special optical treatment, the light transmittance reaches 92%, which hardly affects the presentation effect of 350 CD/m brightness and 3000:1 contrast. Toughened glass has hardness up to Mohs 7, which can resist scratching by hard objects such as keys and coins, and has anti-glare function (surface AG atomization treatment). Under strong light irradiation (such as under the skylight of a shopping mall), it can reduce the reflective area, ensure the consistency of brightness and color of the picture when viewed from different angles, and avoid the local picture being unclear due to reflection.
Display adaptation of touch/non-touch panel of wall-hung advertising machine: the non-touch model adopts pure tempered glass panel, without additional touch layer, which preserves the display clarity to the greatest extent; The touch model (10.1-23.6 inches optional) integrates an infrared touch layer (attached between tempered glass and LCD panel). The thickness of the touch layer is only 0.3mm, the light transmittance reaches 90%, and the attenuation rate of brightness and contrast is controlled within 5%, which not only meets the touch operation requirements (response speed < ＜16ms), but also does not affect the high-definition display effect, and is suitable for self-service inquiry, interactive advertising and other scenes.
D, collaborative optimization of display parameters, system and power consumption
Adaptability of dual systems of wall-mounted advertising machine to display effect: Windows/Android dual systems are supported, and Android system (1G+8G) optimizes color rendering algorithm according to the display characteristics of LCD, which can automatically match 3000:1 contrast parameters when playing local videos and pictures, and restore the true colors of content; Windows system (4G+128G) supports professional image editing software (such as Photoshop and Premiere), which can manually adjust brightness and contrast parameters to meet the requirements of making and previewing advertisement content of wall-mounted advertising machine, and ensure that the final playback effect is consistent with the design draft.
Display stability under low power consumption: the built-in power supply power is less than ＜220W W. While maintaining the brightness of 350 CD/m and the refresh rate of 60Hz, through intelligent backlight adjustment technology, when playing static pictures (such as posters), the backlight power is automatically reduced (by about 20%), but the contrast is kept unchanged, which not only saves energy consumption, but also avoids the color distortion of the pictures; According to the actual measurement, the average daily power consumption (running for 12 hours) of this model is only 1.8-3.2 degrees (depending on the size difference), which is much lower than that of ordinary advertising machines of the same size (about 4.5 degrees), taking into account the requirements of high-definition vision and energy saving.
